Abstract:

Fuel consumption per hectare of tilled land for the conventional or maximum tillage, reduced tillage using a multi-task machine, and no-tillage using a direct drill planter has been studied and compared. Time taken and number of tractor trips needed for performing tillage operations were used for comparison. Yield of crop per hectare was also used for the study. Duncan’s multiple range test was used to compare and analyse the data. Results of fuel consumption were 59.33, 29.67 and 14.33 l/ha for the max. tillage, reduced tillage, and no-tillage cases, respectively. The corresponding yield of crop for these methods were 8.07, 7.90, and 6.33 t/ha, respectively. Therefore, the reduced and no-tillage methods provide enough energy saving per ton of yield to justify their use as good replacements for the max. tillage method in Iran. Also, considering land conditions in Iran, use of direct drill planters is recommended for dry cultivated or traditionally irrigated farms, and multi-task machinery for all types of irrigation systems and land conditions.

Abstract:

The effect of three kinds of fuels used to supply a diesel engine on its characteristics, fuel consumption, and emissions was studied. The fuels comprised pure diesel, a blend of diesel with 6% of methyl ester of yellow grease in the form of rapeseed oil, and a blend of diesel with methyl ester of brown grease in the form of goose fat. The chromatographic analysis was conducted for these fuels, and the results are presented. Two tests, comprising measurement of fuel consumption and engine emissions, were conducted on a vehicle with a diesel engine operating under zero load and under full load. The engine’s characteristics, including both power and torque versus speed, were determined under full engine load. The results of these tests are presented in this paper. The results indicated that the use of different methyl ester-based biodiesel blends with the same content of diesel to supply the diesel engine resulted in different fuel consumption and emissions of the engine not only in comparison to the supply of pure diesel but between biodiesels analyzed.

Abstract:

In this study, effect of anisole additive into the diesel fuel on performance and emission parameters of diesel engines was investigated. Instead of structural changes which are more difficult and expensive, development of fuel technologies is preferred to provide reduction on exhaust gas emissions which are harmful to environment and human health. Therefore, in this experimental study, anisole was used as additive into diesel fuel with the volumetric ratio of 1,5%, 3% and 5%. The performance characteristics and exhaust emissions of a four cylinder, four stroke, naturally aspirated, water cooled, direct injection compression ignition engine fueled with modified fuels were analyzed. Engine was subjected constant speed, full load conditions during tests. Engine power, torque, specific fuel consumption, carbon monoxide, nitrogen oxide and carbon dioxide emissions were measured and results were evaluated. Changes in performance parameters were negligible for all ratios of modified fuels except specific fuel consumption. Finally, while carbon monoxide gas emissions were increased with anisole additive, carbon dioxide and nitrogen oxide gas emissions were decreased.

Abstract:

It remains unclear whether the decision to cook with both polluting and cleaner-burning fuels (‘fuel stacking’) serves as a transition phase towards the full adoption of clean-cooking practices, or whether stacking allows households to enhance fuel security and choose from a variety of cooking technologies and processes. This paper offers a unique contribution to the debate by positioning fuel stacking as the central research question in the exploration of existing household survey data. This research analyses the World Bank’s Multi-Tier Framework survey data concerning energy access and cooking practices in Cambodia, Myanmar, and Zambia. Its novel approach uses fuel expenditure data to group urban households according to the intensity of biomass consumption (wood, charcoal) relative to modern fuel consumption (electricity, gas). The research explores how different fuel-stacking contexts are associated with factors related to household finances, composition, experiences of electricity, and attitudes towards modern fuels. This study shows the diversity of characteristics and behaviours associated with fuel stacking in urban contexts, thus demonstrating the need for fuel stacking to feature prominently in future data collection activities. The paper ends with five key recommendations for further research into fuel stacking and its role in clean-cooking transitions.

Abstract:

The increase in greenhouse gas emissions and our dependence on fossil fuels have motivated researchers to seek the use of renewable fuels in internal combustion engines, which can be produced locally and have clean combustion. The blending method in diesel engines has been recognized as an effective alternative to partially or totally replace the use of diesel fuel. In this regard, this paper studied the operation of a small engine-generator set in mono-fuel mode (diesel fuel - DO) and in dual-fuel mode using hydrous ethanol (HET) and castor oil (OM) blends, indicating a total replacement of diesel fuel. Efficiency, power, specific fuel consumption and gaseous emissions were assessed in a single cylinder diesel cycle engine. The percentages in volume of the HET-OM samples were: 75% - 25%, 70% - 30%, 60% - 40%, and 50% - 50%. The exhaust gas temperature decreased with the mixtures. Carbon monoxide emission decreased 57%, carbon dioxide decreased 9.8%, and nitrogen oxides reduced 19%. It was also observed that the percentage of smoke opacity tends to decrease close to zero with addition of ethanol. Hydrocarbon emissions increased with rising of the OM concentration and the same for the specific fuel consumptions, which was 25.4% higher than diesel fuel. The best fuel conversion efficiency was achieved with the blend HET75-OM25, being 9% higher compared to diesel fuel operation. Power on diesel fuel operation showed a better result keeping stable, with the increase of the compression ratio and the delay of the start of injection. In general, the results confirmed that the performance is comparable to that of diesel fuel, indicating that renewable fuels appear as an alternative for the reduction of the environmental impacts and the reduction of fossil fuels consumption.

Abstract:

The use of internal combustion motors has various positive and negative impacts. A large number of motorized vehicles affect the high demand for fuel. Fuel oil is a vital economic object because it dramatically influences the financial entity, namely the increase in goods and services. What can do several things to reduce the high demand for this fuel, namely by looking for alternative fuels or finding fuel economy. The purpose of this study was to determine the impact of adding additives to fuel on fuel consumption. The research method applies an experimental procedure in which the percentage of mixing premium fuel with additives between camphor and eco racing with a content of 1 - 4 grams of additive for each sample tested on a vehicle. The results obtained are adding additives the properties of premium fuels change in terms of fuel consumption where the addition of several types of additives can reduce the rate of fuel consumption. The results obtained are that with the addition of these additives, the fuel consumption becomes more efficient by a difference of approximately 6 ml/minute.

Abstract:

This paper describes the effect of a mixture of rapeseed methyl ester and diesel oil on fuel consumption and power parameters of tractor engine. The hydraulic dynamometer was used to load the engine of Zetor Forterra 8641 tractor over rear power take-off. The measured tractor is almost new with less than 100 h worked. The measurements were realized for several ratios of diesel oil and rapeseed methyl ester (from pure diesel to pure rapeseed methyl ester). The engine was loaded by the dynamometer in several working points which were predefined by engine speed and its torque. The fuel consumption was measured by the flow meter in each of these points. The reduction of engine’s power parameters and the increase of specific fuel consumption are expected due to the nature of rapeseed methyl ester such as e.g. lower calorific value.

Abstract. The rising cost of fossil fuels, global warming from greenhouse gas (GHG) emissions, unreliable grid supply electricity, and overdependence on hydropower electricity have resulted in low electricity per capita in Nigeria. This study was undertaken to produce, purify, and use biogas as a fuel to generate electricity with a 3.5 kW spark-ignition engine generator and determine its effect on GHG emissions, power output, and fuel consumption. Unpurified and purified biogas were used as fuels. The biogas was purified in water and in a calcium chloride solution. The fuels used to power the generator were gasoline, unpurified biogas, water-purified biogas, and calcium chloride-purified biogas. The GHGs measured were carbon monoxide, carbon dioxide, nitrogen oxide, and sulfur dioxide. The biogas was produced with a 3 m3 capacity floating-drum biogas plant. The total solids concentration and carbon/nitrogen ratio of the influent and effluent slurries were determined. The effects of fuel type on GHG emissions were determined in a 4 × 4 factorial experiment with three replicates in a completely randomized design. The effects of fuel type on power output and fuel consumption of the generator were determined in a 4 × 2 factorial experiment with three replicates in a completely randomized design. The results were analyzed using analysis of variance at p = 0.05. Duncan’s new multiple range test was used to separate means when there was significant difference. The results obtained showed that carbon dioxide emission was not affected by purification of the biogas because the carbon dioxide emissions from the fuel types were not significantly different. The carbon monoxide emission was much higher from the unpurified biogas than from the purified biogas fuels, although gasoline had the highest carbon monoxide emission. The water-purified biogas had the least carbon monoxide and sulfur dioxide emissions. The unpurified biogas had the least nitrogen oxide emission compared to the purified biogas fuels and gasoline. The power output from the unpurified biogas was not significantly different from that of gasoline and was higher than the purified biogas fuels. The fuel consumptions of the purified biogas fuels were not significantly different. The water-purified biogas is recommended for use as fuel for the production of electricity from a spark-ignition engine generator. Keywords: Biogas, Effects, Electricity, Fuel consumption, Greenhouse gas emissions, Power output.

Abstract:

In this study, we tested a natural draft gasifier, currently implemented in Senegal and the traditional three stones fire (TSF) in the laboratory, using the protocol of water boiling test (WBT). Pollutants emissions from three types of biomass full were investigated in this work. Our results show that, burning the same wood (Cordyla Pinnata, dimb), the gasifier had a fuel consumption 37% lower than the traditional three stones, and decrease emissions factors of fine particulate matter (PM) by 74%, organic carbon (OC) by 59 % and elemental carbon (EC) by 55%. The gasifier has also shown to reduce fuel used and emissions compared with the three stones using Casuarina Equisetifolia (Filao) though to a minor extent: 24 % in fuel consumption and emissions reduction of 53% of PM, 55% of OC and 18% EC. The micro-gasifier using typha pellets is the cooking system the most efficient with a reduction 70% of fuel and more than 85% of emissions comparing to the 3-stones-dimb combination. Our results agree with other studies and confirm that gasifier have a very low fuel consumption and low emissions of climate forcing particles. Further field studies are needed to evaluate the adoption of these new stoves and fuels and to analyze fuel consumption and emissions under real-world cooking practice

Abstract:

The increasing of vehicle uses will make the increasing in fuels consumption. In the other hand, the reserves of fossil fuels as a fuel in vehicles are always decreasing. In order to anticipate the lack of fossil fuels, there is some alternatives energy that has to substitute the fossil fuels. One of the alternative energy is HHO Gas. HHO gas is a gas that was produced by the electrolysis of water. Water as an abundant material in earth can be an alternative energy that replace or substitute fossil fuel. In this research, HHO gas will be used as a supplement in fuels. So the vehicles use two fuels (bi-fuel. )The aim of this research is to analyze the performance of uses HHO gas in vehicles. The HHO gas will be produced by different water, such as aquadest, land water, sea water. The performance analysis was focused in the fuel consumption and the efficiency of thermal engine oil. The analysis result shows that the addicted HHO gas can make the efficiency of fuel consumption better. The highest efficiency fuel consumption is in the fuel with HHO gas from aquadest (19.95%). But the best efficiency in thermal engine oil is in HHO gas from sea water (0.84 oC). Keywords: HHO, performance, engine, bifuel

Abstract:

Purpose. To identify environmental climatic impacts resulting from the biodiesel fuel use for vehicles (Vs). Methodology. The methods are based on computation of natural resource consumption and toxic emission with the help of environmental footprint calculator being a software program. Findings. The results of integral assessment of the environmental impact (namely, consumption of water, power, natural resources, and emission of greenhouse gases 2, and NOx in terms of such base traction trucks as VOLVO FM, FH, FE, and FL) were computed for biodiesel fuel types 0, 7, 30, 100 depending upon different standards of EURO propellants. Both positive and negative environmental impact factors have been determined for consuming biofuels during full lifecycle of Vs. It has been defined that minor decrease in 2 emission owing to the use of standard modern biodiesel fuel is followed by significant increase in NOx emission as well as power and water consumption in terms of first-generation biodiesel fuel utilization. VOLVO F Vs were applied for comparative analysis of environmental impact by first-generation biodiesel fuel (i.e. 7, 30, 100) and second-generation fuel being hydrotreated vegetable oil (HVO). Similar tendencies were recognized. Moreover, opportunity to apply biodiesel fuels along with other measures decreasing 2 emission was analyzed. Originality. Originality is stipulated by the use of the integrated assessment of impact of vehicles on climate change as well as use of natural resources while applying biodiesel fuel for vehicles. Practical value. It is possible to forecast environmental consequences resulting from the use of various biodiesel fuels for Vs.

Abstract:

Hunger for energy consumption is booming due to industrialization and globalization causes the consumption of fossil fuel resources and searching for unconventional fuels. Among all other available unconventional fuels, biodiesel has achieved significant considerations globally. The present research is catering production of biodiesel from eucalyptus species as forest waste using fast pyrolysis. The derived biodiesel was tested for its various physical and chemical properties using standard test methods (IS 1448, ASTM D 4868). The major properties of the derived biodiesel are similar to the existing diesel fuel. The obtained biodiesel is having a cetane number of 54, the kinematic viscosity of 5.83 cSt, and a calorific value of 7,850 kcal/kg. The derived biodiesel was tested in a fixed compression ratio diesel engine. The variable parameters were blending ratio and engine load. The engine gave the best performance at B100 with full load gave the highest 33.57% BTE, 0.31 kg/KWhr of lowest SFC, and minimum ignition delay. Its emission characteristics also follow current exhaust gas emission norms as per BS6 in India. NO<sub>x</sub> emission was a minimum of 235 ppm at B100, hydrocarbon emission was a minimum of 0.038 g/KWhr at full load with B100 and the least CO emission of 2.85 g/KWhr was observed at full load with pure biodiesel (B100). Thus, obtained biodiesel can be used as a fuel in the CI engine as an alternative source of energy.

Abstract:

Currently, the disposal and recycling of the alcohol industry products creates a number of difficulties due to the lack of well-established recycling lines in Ukraine. Since 1998, eight enterprises of the state-owned concern Ukrspirt have been converted to produce high-octane oxygen-containing additives (CFCs) for ethanol-based fuels to organize the processing of waste from the alcohol industry. During this time, they produced 28.2 thousand tonnes of CALs, but CALA enterprises face great difficulties in selling their products, as they are new and expensive. The influence of fusel oil additives on commodity fuels on the main physical and technical indicators of the obtained alternative fuels is considered in the paper. According to the results of studies of octane number, we have established the optimal compositions of fuel mixtures of fusel oils with gasoline A-80 can contain up to 10% of the latter. For mixtures of fusel oils with diesel fuel by cetane number, their optimum content in diesel fuel is from 4 to 10% by volume. But, according to the trends of the development of diesel engines, the compression ratio increases, which allows the use of diesel fuel with higher cetane number, and therefore it is possible to raise the content of fusel oils in diesel fuel to 12%. According to the results of studies of the environmental performance of the ZIL-130 engine when fusel oils are added to commercial gasoline in an amount of 2 to 10% vol. the CO content in ICE exhaust gases decreases by 9.3%, fuel consumption increases by 6.5%, hydrocarbons by 10.2% and nitrogen oxide by 16.9%. As a result of increasing the content of fusel oils in diesel from 0 to 6%, there is an increase in mass flow rate of fuel to 6.1%, an increase in the concentration of hydrocarbons to 10% and nitrogen oxides by 1.9% in the exhaust gases of the engine D21A1. Thus, as we see today, along with traditional fuels for internal combustion engines, it is possible to use their alternative substitutes quite efficiently both in their pure form and in mixtures with them. There are all prerequisites for this in Ukraine and the region, the only question is the financing of these projects.

Abstract:

A flowing, single-pass heat exchanger test rig, with a fuel capacity of 189 liters, has been developed to evaluate jet fuel thermal stability. This “Phoenix Rig” is capable of supplying jet fuel to a 2.15 mm i.d. tube at a pressure up to 3.45 MPa, fuel temperature up to 900 K, and a fuel-tube Reynolds number in the range 300–11,000. Using this test rig, fuel thermal stability (carbon deposition rate), dissolved oxygen consumption, and methane production were measured for three baseline jet fuels and three fuels blended with additives. Such measurement were performed under oxygen-saturation or oxygen-starved conditions. Tests with all of the blended fuel samples showed a noticeable improvement in fuel thermal stability. Both block temperature and test duration increased the total carbon deposits in a nonlinear fashion. Interestingly, those fuels that need a higher threshold temperature to force the consumption of oxygen exhibited greater carbon deposits than those that consume oxygen at a lower temperature. These observations suggested a complicated relationship between the formation of carbon deposits and the temperature-driven consumption of oxygen. A simple analysis, based on a bimolecular reaction rate, correctly accounted for the shape of the oxygen consumption curve for various fuels. This analysis yielded estimates of global bulk parameters of oxygen consumption. The test rig yielded quantitative results, which will be very useful in evaluating fuels additives, understanding the chemistry of deposit formation, and eventually developing a global chemistry model.

Abstract:

Environmental degradation has come about for a number of factors including the use of fossil fuels in vehicles for everyday use. This paper attempts to understand the relationship between fuel consumption and various engine performance parameters under laboratory conditions in order to see how various factors contribute to the overall fuel consumption. The framework for testing has been decided as the New European Drive Cycle (NEDC) given its various testing advantages against other driving cycles. A test rig was applied to simulate the NEDC under laboratory conditions. The findings from this study provide information how vehicular fuel consumption varies with such driving parameters as vehicle speed, acceleration, and throttle position. They can be used to predict fuel consumption under any real life driving conditions, which will contribute to reducing fuel consumption in future vehicle design..

Abstract:

ABSTRACT Diesel cycle engines are widely used in a wide range of agricultural activities. Recently, with the increasing use of biodiesel mixed with petroleum diesel and the introduction of pollutant emission regulations for agricultural and road machinery, there has been a growing migration from mechanical to electronic fuel injection systems. In this experiment, the primary aim was to verify the behavior of a diesel engine, electronically managed, with controlled variation of the fuel feeding system parameters (injection time and volume injected). A four-cylinder agricultural tractor with a turbocharged engine and a common rail electronic fuel injection system was used. Tests with diesel B10 and blends of 20 and 30% biodiesel were carried out, all with 10 ppm of sulfur and the injection system electronically reprogrammed. The tests were performed under full engine load from 1,300 to 2,000 rpm. The torque, power and fuel consumption were evaluated. Advancing the injection point increased the power and decreased the specific fuel consumption for all fuels. The greater amount of injected fuel provided average power gain of up to 14.96% and average torque gain of 15.50%.

Abstract:

Jatropha biodiesel was produced from neat jatropha oil using both esterification and transesterification processes. The free fatty acid value content of neat jatropha oil was reduced to approximately 2% from 12% through esterification. Aluminium oxide (Al2O3) and cerium oxide (CeO2) nanoparticles were added separately to jatropha biodiesel in doses of 100 ppm and 50 ppm. The heating value, acid number, density, flash point temperature and kinematic viscosity of the nanoadditive fuel samples were measured and compared with the corresponding properties of neat fossil diesel and neat jatropha biodiesel. Jatropha biodiesel with 100 ppm Al2O3 nanoparticle (J100A100) was selected for engine testing due to its higher heating value and successful amalgamation of the Al2O3 nanoparticles used. The brake thermal efficiency of J100A100 fuel was about 3% higher than for neat fossil diesel, and was quite similar to that of neat jatropha biodiesel. At full load, the brake specific energy consumption of J100A100 fuel was found to be 4% higher and 6% lower than the corresponding values obtained for neat jatropha biodiesel and neat fossil diesel fuels respectively. The NOx emission was found to be 4% lower with J100A100 fuel when compared to jatropha biodiesel. The unburnt hydrocarbon and smoke emissions were decreased significantly when J100A100 fuel was used instead of neat jatropha biodiesel or neat fossil diesel fuels. Combustion characteristics showed that in almost all loads, J100A100 fuel had a higher total heat release than the reference fuels. At full load, the J100A100 fuel produced similar peak in-cylinder pressures when compared to neat fossil diesel and neat jatropha biodiesel fuels. The study concluded that J100A100 fuel produced better combustion and emission characteristics than neat jatropha biodiesel.

Abstract:

Thorium-plutonium mixed oxide (Th-MOX) fuel has become one of the most promising solutions to reduce a large and increasing plutonium stockpile. Compared with traditional uranium-plutonium mixed oxide (U-MOX) fuels, Th-MOX fuel has higher consumption rate of plutonium in LWRs. Besides, thorium based fuels have improved thermomechanical material properties compared with traditional U-MOX fuels. Previous studies on a full Th-MOX core have shown reduced efficiency in reactivity control mechanisms, stronger reactivity feedback, and a significantly lower fraction of delayed neutrons compared with a traditional uranium oxide (UOX) core. These problems complicate the implementation of a full Th-MOX core in a similar way as for a traditional U-MOX core. In order to reduce and avoid some of these issues, the introduction of a lower fraction of Th-MOX fuel in the core is proposed. In this study, one-third of the assemblies are Th-MOX fuel, and the rest are traditional UOX fuel. The feasibility study is based on the Swedish Ringhals-3 PWR. The results show that the core characteristics are more similar to a traditional UOX core, and the fraction of delayed neutrons is within acceptable limits. Moreover, the damping of axial xenon oscillations induced by control rod insertions is almost 5 times more effective for the 1/3 Th-MOX core compared with the standard core.

Abstract:

Water electrolyzed hydroxyl gas (HHO or Brown gas) and Compressed Natural Gas (CNG) are the important and promising alternatives to the pure fossil fuels. The global concern is about greenhouse gas emission in the environment and ambient air pollution steered by mass consumption of fossil fuels in automobile industries and power sectors. In this study, the combustion, performance and emission characteristics of HHO gas and CNG mixtures supplied to intake manifold of CI (compression ignition) engine using diesel as a pilot fuel are studied. The same investigations are repeated with various EGR (Exhaust Gas Recirculation) proportions to study the impact of EGR on multi fuel mode (diesel+HHO gas+CNG) in a diesel engine. The multi fueled engine performance, combustion and emission parameters are presented and compared with graph and analytical discussion. The results indicated that at full load, the NOx emission decreased by 4% (without EGR), 18% (with 10% EGR) and smoke density decreased by 78% with multi fuel mode comparing to the pure diesel operation at constant speed of 1500rpm. Also more enhanced performance by improving the brake thermal efficiency (BTE) by 17%, reducing the brake specific energy consumption (BSEC) by 19%, resulted better fuel economy, and power due to better combustion.

Abstract:

Stochastic simulation was conducted to analyse the fuel consumption of a shovel-truck system. An example shovel-truck system, comprising a single shovel and four trucks was considered. At 95% confidence interval, the monthly simulated fuel consumption by the shovel-truck system was found to be about 198 127 litres against the actual fuel consumption of 203 772 litres, registering a variance of -2.70%. About 22 000 litres of fuel was consumed per month due to truck waiting. Optimising the fuel consumption and truck waiting time can result in significant fuel savings. The paper demonstrates that stochastic simulation is an effective tool for optimising the utilisation of fossil-based fuels in mining and related industries.

The climate and fuel supply have been problematic emphasis on alternative fuels for combustion engines. Different research studies tested various alternative fuels. In this connection, biodiesel is the most promising diesel fuel based on a literature survey. In this paper, the prospects and potential for the use of biodiesel and increasing biodieseldiesel blending are studied by a fixed compression ratio, Optimum blending and enhanced performance engine parameter and pollution control should be proposed based on experiments. Experiments for a set compression ratio (17:1) undertaken utilising biodiesel cotton seed oil (CSME) diesel blends, i.e. B0, B10, B20, B30, without full loading rates, compared to the base cases (e.g. diesel engine fuel). The parameters may evaluate the fuel consumption and thermal efficiency of the brakes, Unburned hydrocarbons, and nitrogen oxides in emission of carbon monoxide. The results concluded that, B20 (20% biodiesel and 80% diesel) is the most efficient compared to other mixtures.

Biodiesel as a renewable and environmentally friendly alternative fuel derived from natural fats or vegetable oils has better lubricating properties and much higher cetane ratings than today's lower sulfur diesel fuels. It is considered as an attractive alternative to replace diesel fuels. In order to investigate application of biodiesel on vehicle diesel engines, the power and fuel economies performances of a diesel fueled soybean biodiesel with different blending ratios were tested under different engine loads and speeds. Experimental results show that, compared with diesel fuel, with increase in the biodiesel in the blends, the brake power and torque, and the brake specific energy consumption increase but the fuel consumption per hour and brake specific fuel consumption decrease.

Abstract:

A fuel stratification concept is being researched and developed in a three-valve twin-spark ignition engine. This concept requires that two different fuels or fuel components be introduced into the cylinder separately through two independent inlet ports. The fuels will be stratified laterally by means of strong tumble in the cylinder. Similar to the traditional air/fuel stratification engine, this fuel stratification engine can operate in very lean mixture or high exhaust gas dilution at part loads to reduce fuel consumption and NOx emissions. While at high-load operation, a higher compression ratio may be allowed owing to a potential increase in antiknock features if the lower research octane number (RON) fuel or component is ignited first, leaving the higher RON fuel in the end gas region. As a result, the fuel economy can be improved not only at part loads but possibly at full loads as well. This paper reports the development of such a fuel stratification engine. Firstly, the intake system of the engine was modified to produce a strong tumble flow which was measured by a digital particle image velocimetry (PIV) system. Then, a two-tracer planar laser induced fluorescence (PLIF) system was developed to visualize the fuel stratification in the cylinder. The engine combustion at part and full loads was also tested and analysed from cylinder pressure history. These research results show that the present strong tumble flow was characterized by a symmetrically distributed mean velocity in the intake stroke and a very small velocity component along the direction of the tumble rotational axis in the compression stroke. This flowfield created good fuel stratification laterally. The lean burn limit was considerably extended at part loads, and the knock limit at high loads also had a noticeable difference when higher and lower RON fuels respectively were ignited first.

Abstract:

Biodiesel is an alternative fuel for diesel engines which doesn?t contain pollutants and sulfur; on the contrary it contains oxygen. In addition, both physical and chemical properties of sunflower oil methyl ester (SME) are identical to diesel fuel. Conversely, diesel and biodiesel fuels are widely used with some additives to reduce viscosity, increase the amount of cetane, and improve combustion efficiency. This study uses diesel fuel, SME and its mixture with aviation fuel JetA-1 which are widely used in the aviation industry. . Fuel mixtures were used in 1-cylinder, 4-stroke diesel engine under full load and variable engine speeds. In this experiment, engine performance and emission level are investigated. As a conclusion, as the JetA-1 ratio increases in the mixture, lower nitrogen oxide (NOx) emission is measured. Also, specific fuel consumption is lowered.

Potential possibility of the butyl ether (BE, oxygenates of di-ether group) was analyzed as an additives for a naturally aspirated direct injection diesel engine fuel. Engine performance and exhaust emission characteristics were analyzed by applying the commercial diesel fuel and oxygenates additives blended diesel fuels. Smoke emission decreased approximately 26% by applying the blended fuel (diesel fuel 80 vol-% + BE 20vol-%) at the engine speed of 25,000 rpm and with full engine load compared to the diesel fuel. There was none significant difference between the blended fuel and the diesel fuel on the power, torque, and brake specific energy consumption rate of the diesel engine. But, NOx emission from the blended fuel was higher than the commercial diesel fuel. As a counter plan, the EGR method was employed to reduce the NOx . Simultaneous reduction of the smoke and the NOx emission from the diesel engine was achieved by applying the BE blended fuel and the cooled EGR method.

Abstract:

An empirical model is presented which relates fractional reduction in loading to fuel element diameter and moisture content for surface and aerial fuels consumed near the fire front in a spreading crown fire. The model is based upon data from a series of experimental crown fires in immature jack pine. Its intended use is to permit calculation of fuel consumption per unit area (kg/m2) needed to estimate edge intensity (kW/m) from the spread rate of a crown fire. Model predictions of small fuel component fractional loading reduction had a root-mean-square error of almost 0.2 for our calibration data set. Most of the error arises from the model prediction of complete consumption of crown foliage, some of which was not exposed to flame in the fires of our data set. The model does not address the longer term burning of duff and large woody fuels.

Abstract:

The rise of energy demand and ecological contaminations encourage the utilization of alcohol bases on substitutes fuels in spark ignition (SI) engine. The fusel oil is a byproduct acquired from fermentation process with higher alcohol content. It has high-octane and less exhaust emissions; therefore, it takes significant place between the substitutes fuels. During this study, the impact of utilizing mixtures of pure gasoline & fusel oil on engine exhaust emissions & performance has been evaluated after water extraction from fusel oil. A single-cylinder, four-stroke SI engine has been utilized in these tests. The examinations execute at different speeds. The experiment fuels mixed with fusel oil at proportions of 5%, 10%, 20%, and 30%. At each speed, the engine’s performance & emissions measurement have been conducted. During the experimentations, it has been noticed that the torque (T) and specified fuel consumption (SFC) rises as the quantity of fusel oil risen in the mixture. Carbon monoxide (CO) and carbon dioxide (CO2) emissions are decreased as the quantity of fusel oil is raised in mixtures.

Abstract:

In the next decade, due to the desire for significant reduction in the carbon footprint left by the aviation sector and the development of a sustainable alternatives to petroleum, fuel from renewable sources will play an increasing role as a propellant for turbine aircraft engines. Currently, apart from five types of jet fuel containing synthesized hydrocarbons that are certified by the ASTM D7566 standard, there is yet another synthetic blending component that is at the stage of testing and certification. Hydroprocessed esters and fatty acids enable the production of a synthetic component for jet fuel from any form of native fat or oil. Used feedstock affects the final synthetic blending component composition and consequently the properties of the blend for jet fuel and, as a result, the operation of turbine engines. A specialized laboratory test rig with a miniature turbojet engine was used for research, which is an interesting alternative to complex and expensive tests with full scale turbine engines. The results of this study revealed the differences in the parameters of engine performance and emission characteristics between tested fuels with synthetic blending components and neat jet fuel. The synthetic blending component was obtained from two different feedstock. Noticeable changes were obtained for fuel consumption, CO and NOx emissions. With the addition of the hydroprocessed esters and fatty acids (HEFA) component, the fuel consumption and CO emissions decrease. The opposite trend was observed for NOx emission. The tests presented in this article are a continuation of the authors’ research area related to alternative fuels for aviation.

Abstract:

In this paper, fuel consumption for a TOYOTA ECHO PLUS-2ZZ-GE-02 model light vehicle has been analyzed by changing the front right toe-out angles. Acomputerized wheel alignment machine (Best-5800) has been used to measure the misalignment of the wheels. Fuel consumptions were measured for different front right toe-out angles adjusted by the machine while the car travel is 6 km. It was found that due to misalignment of front right toe-out angle (from 0.00° to -2.53°), the fuel consumption rate is increased upto 41.21%. The pearson’s correlation coefficient was found as r(αF)abs.=0.99, which proves a very strong correlation between fuel consumption and front right toe-out angle. It has been also analyzed the retation between front right toe-out angle and fuel consumption of vehicle using by experimental method to predict the fuel consumption. The mathematical model proposed in this study can also used to predict the amount of fuel consumption by the different model of vehicles.

Abstract:

Most of the fuels used in internal combustion engines are liquid fuels. The magnetic behavior of fuel leads to a change in the interaction of hydrocarbon and oxygen molecules. This study aimed to evaluate the fuel consumption and engine vibration (time domain) of the Perkins A63544 diesel engine using magnetized fuel. The vibration of an internal combustion engine can cause failure in engine components and discomfort and injury to users. Engine vibration behavior changes due to changes in fuel types and engine combustion. Therefore, in this study, the vibration behavior of the tractor engine (Perkins model, four-stroke, direct injection diesel) was evaluated in stationary mode at different engine speeds due to changes in fuel types. Three accelerometers (CTC AC102 model) were used to measure the vibration acceleration. The fuels used included diesel as a normal control and fuels that had been subjected to magnetic field intensities of 1000, 2000, 3000, and 4000 gauss. The longitudinal, vertical, and lateral vibration signals with 5 levels of engine speed were measured. The results illustrated that the vibration root mean square (RMS) values were essentially (p < 0.01) affected by the engine speed, fuel type, and their interactions. It was found that for the 4000-gauss magnetized fuel, the average vibration acceleration using the five velocity settings reduced by 15%, 15.30%, 12.40%, 12.35%, and 15.38% compared to the respective control fuels. The results showed that engine fuel consumption and specific fuel consumption decreased by 2.3% using the 4000-gauss magnetized fuel compared with the normal control fuel.

Abstract:

Over the decades, more attention has been paid to emissions from the means of transport and the use of different fuels and combustion fuels for the operation of internal combustion engines than on fuel consumption. This, in turn, enables research into products that are said to reduce fuel consumption. The report summarizes four studies of fuel-related innovation products. The studies covered by this report are conducted with diesel fuel and usually contain diesel fuel and three additives for it. Manufacturers of additives are based on already existing studies showing a 10-30% reduction in fuel consumption. Comparative experimental studies related to the use of commercially available diesel fuel with and without the use of additives have been performed in laboratory conditions. The studies were carried out on a stationary diesel engine СМД-17КН equipped with brake КИ1368В. Repeated results were recorded, but they did not confirm the significant positive effect of additives on specific fuel consumption. In some cases, the factors affecting errors in this type of research on the effectiveness of fuel additives for commercial purposes are considered. The reasons for the positive effects of such use of additives in certain engine operating modes are also clarified.

Abstract:

Hybrid propulsion and using liquefied natural gas (LNG) as the alternative fuel have been applied on automobiles and some small ships, but research investigating the fuel consumption and emissions over the total voyage of ocean-going cargo ships with a hybrid propulsion and different fuels is limited. This paper tries to fill the knowledge gap by investigating the influence of the ship mission profile, propulsion modes and effects of different fuels on the fuel consumption and emissions of the ship over the whole voyage, including transit in open sea and manoeuvring in close-to-port areas. Results show that propulsion control and electric power generation modes have a notable influence on the ship’s fuel consumption and emissions during the voyage. During close-to-port manoeuvres, propelling the ship in power-take-in (PTI) mode and generating the electric power by auxiliary engines rather than the main engine will reduce the local NOx and HC (hydrocarbons) emissions significantly. Sailing the ship on LNG will reduce the fuel consumption, CO2 and NOx emissions notably while producing higher HC emissions than traditional fuels. The hybridisation of the ship propulsion and using LNG together with ship voyage optimisation, considering the ship mission, ship operations and sea conditions, will improve the ship’s fuel consumption and emissions over the whole voyage significantly.
