Abstract:

Background: Vegetable oil of Fatty Acid Methyl Esters (FAME) that is obtained by triglycerides of transesterification in the presence of methanol, recently, has been highly regarded by scholars for use in diesel engines. These oils can be used as biodiesels in diesel engines and have various benefits (these fuels are renewable, biodegradable, and nontoxic). Objective: In this work, many studies are reviewed in the field of using vegetable oils as biodiesel in diesel engines. Moreover, a simulation study is conducted to compare oxygen and peak pressure of a diesel engine fueled by three different biodiesels in comparison to diesel fuel. We have examined the chemical ignition delay time and kinetic viscosity of biodiesel in the combustion process of diesel engine and the effects of these factors are evaluated on air–fuel mixing and subsequent combustion.

Abstract:

Abstract Biodiesels produced from various feedstocks have been considered as alternative fuels used in internal combustion engines without major modifications. This research focuses on producing biodiesel from waste cooking oil (WCOSD) by the catalytic cracking method using MgO as the catalyst and comparing the engine operating characteristics of the test engine when using WCOSD and traditional diesel (CD) as test fuels. As a result, the brake power of the test engine fueled WCOSD, and traditional diesel is similar. However, the engine fuel consumption in the case of using WCOSD is slight increases in some operating conditions. Also, the nitrogen oxides emissions of the test engine fueled WCOSD are higher than those of CD at all tested conditions. The trend is opposite for hydrocarbon emission as the HC emission of the engine fueled by WCOSD reduces 26.3% on average. The smoke emission of the test engine in case of using WCOSD is lower 17% on average than that of CD. However, the carbon monoxide emissions are lower at the low and medium loads and higher at the full loads. These results show that the new biodiesel has the same characteristics as those of commercial biodiesel and can be used as fuel for diesel engines.

Abstract:

In this paper, the exergy analysis and environmental assessment are performed to the biodiesel and diesel-fueled engine at full 294 Nm and 1800 r/min. The exergy loss rates of fuels are found as 15.523 and 18.884 kW for the 100% biodiesel (BDF100) (obtained from cooking oil) and Japanese Industrial Standard Diesel No. 2 (JIS#2) fuels, respectively. In addition, the exergy destruction rate of the JIS#2 fuel is found as 80.670 kW, while the corresponding rate of the BDF100 is determined as 62.389 kW. According to environmental assessments of emissions and nanoparticles of the fuels, the biodiesel (BDF100) fuel is more environmentally benign than the diesel (JIS#2) fuel in terms of particle concentration and carbon monoxide and hydrocarbon emissions. So, it is better to use this kind of the 100% biodiesels in the diesel engines for better environment and efficiency in terms of the availability and environmental perspectives.

Abstract:

This study examined the use of waste plastic oil (WPO) combined with biodiesel as an alternative fuel for diesel engines, also commonly known as compression ignition engines, and focused on comparison of the basic physical and chemical properties of fuels, engine performance, combustion characteristics, and exhaust emissions. A preliminary study was conducted to determine the suitable ratio for the fuel blends in consideration of fuel lubricity and viscosity, and these results indicated that 10% biodiesel—derived from either palm oil or castor oil—in waste plastic oil was optimal. In addition, characterization of the basic properties of these fuel blends revealed that they had higher density and specific gravity and a lower flash point than diesel fuel, while the fuel heating value, viscosity, and cetane index were similar. The fuel blends, comprised of waste plastic oil with either 10% palm oil biodiesel (WPOP10) or 10% castor oil biodiesel (WPOC10), were selected for further investigation in engine tests in which diesel fuel and waste plastic oil were also included as baseline fuels. The experimental results of the performance of the engine showed that the combustion of WPO was similar to diesel fuel for all the tested engine loads and the addition of castor oil as compared to palm oil biodiesel caused a delay in the start of the combustion. Both biodiesel blends slightly improved brake thermal efficiency and smoke emissions with respect to diesel fuel. The addition of biodiesel to WPO tended to reduce the levels of hydrocarbon- and oxide-containing nitrogen emissions. One drawback of adding biodiesel to WPO was increased carbon monoxide and smoke. Comparing the two biodiesels used in the study, the presence of castor oil in waste plastic oil showed lower carbon monoxide and smoke emissions without penalty in terms of increased levels of hydrocarbon- and oxide-containing nitrogen emissions when the engine was operated at high load.

Abstract:

Purpose Energy is the prime mover of economic growth and is vital to the sustenance of a modern economy. Future economic growth depends heavily on the long-term availability of energy from sources that are affordable, accessible and environmentally friendly. Regulating the sulfur content in diesel fuel is expected to reduce the lubricity of these fuels, which may result in increased wear and damage of fuel injection systems in diesel engines. Design/methodology/approach The tribological properties of the biodiesels as additive in pure petro-diesel are studied by ball-on-ring wear tester to find optimal concentration, and the mechanism of the reduction of wear and friction will be investigated by optical microscopy. Findings Studies have shown that low concentrations of biodiesel blends are more effective as lubricants because of their superior polarity. Using biodiesel as a fuel additive in a pure petroleum diesel fuel improves engine performance and exhaust emissions. The high biodegradability and superior lubricating property of biodiesel when used in compression ignition engines renders it an excellent fuel. Originality/value This detailed experimental investigation confirms that biodiesel can substitute mineral diesel without any modification in the engine. The use of biofuels as diesel engine fuels can play a vital role in helping the developed and developing countries to reduce the environmental impact of fossil fuels.

Abstract:

For economic and social development of any country energy is one of the most essential requirements. Continuously increasing price of crude petroleum fuels in the present days coupled with alarming emissions and stringent emission regulations has led to growing attention towards use of alternative fuels like vegetable oils, alcoholic and gaseous fuels for diesel engine applications. Use of such fuels can ease the burden on the economy by curtailing the fuel imports. Diesel engines are highly efficient and the main problems associated with them is their high smoke and NOx emissions. Hence there is an urgent need to promote the use of alternative fuels in place of high speed diesel (HSD) as substitute. India has a large agriculture base that can be used as a feed stock to obtain newer fuel which is renewable and sustainable. Accordingly Uppage oil methyl ester (UOME) biodiesel was selected as an alternative fuel. Use of biodiesels in diesel engines fitted with mechanical fuel injection systems has limitation on the injector opening pressure (300 bar). CRDI system can overcome this drawback by injecting fuel at very high pressures (1500-2500 bar) and is most suitable for biodiesel fuels which are high viscous. This paper presents the performance and emission characteristics of a CRDI diesel engine fuelled with UOME biodiesel at different injection timings and injection pressures. From the experimental evidence it was revealed that UOME biodiesel yielded overall better performance with reduced emissions at retarded injection timing of -10° BTDC in CRDI mode of engine operation.

Abstract:

Abstract Biodiesels from vegetable oils are also gaining momentum as a encouraging fuels which acts as alternative for agricultural diesel engines. Even though there is a slight penalty in the performance parameters by the usage of vegetable biodiesel fuels in diesel engines because of their high viscosity, there is considerable reduction in emissions which is dominant factor from the environmental perspective. In the present experimental work four fuels Canola (20% Canola oil plus 80% Diesel) biodiesel (B20C),Sesame (20% Sesame oil plus 80% Diesel) biodiesel (B20S), B20C blended with 5% n-butanol(B20C5B) and B20S is blended with 5% nbutanol(B20S5B) have tried as an alternative fuels to the Diesel. In the primitive stage tests were supervised on diesel engine with diesel. Thereafter in the second stage, tests were directed at identical operating conditions by using B20C, B20S and their blends as biodiesels. The engine important performance parameters brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) and also the emission characteristics hydrocarbons (HC), carbon monoxide (CO), smoke opacity and nitrogen oxides (NOx) are evaluated. The results are contrasted with respect on base line data (diesel). From the experimental readings it was observed that the BTE of B20C, B20S, B20C5B and B20S5B at 100% load decreased by 2.64%,1.9 %,1.41% and 0.94% respectively, relative to diesel (D). At maximum loading condition BSFC for diesel,B20C,B20S,B20C5B and B20S5B are 0.254, 0.284,0.273,0.270 and 0.260kg/kWh. Overall, it is concluded that the emission characteristics of HC, CO and Smoke opacity are dropped for all tested biodiesels when compared to diesel fuel.

Abstract:

After the oil crisis in 1973, renewable sources of energy are gianing more interest due to multiplicity feedstocks and lower pollution compared with fossil fuels. Wide agricultural lands through the world are not fully benefited. Therefore, farming should include the production of non-food products which are suitable to weather conditions of these lands. This leads to the production of biodiesels as renewable fuel for the domestic energy market, to reduce the dependence on fossil fuels. Biodiesel have gained a large interest of researches during the last few decades, the major reason to find an alternative fuel, is the increasing worry about the greenhouse gas effects and environmental regulations. Blended palm biodiesel with ordinary diesel fuel have been approved as a fuel for compression ignition engines without any modification. Palm biodiesel application is relatively limited to its poor cold flow properties characteristics. Many experimental studies are conducted to evaluate the influence of using different additives with Palm Oil Methyl Ester (POME) biodiesel/diesel blends on fuel properties (viscosity, cold properties, anticorrosiveness, cetane number, heat content, volatility) and engine performance. This article provides a literature survey on the effect of different additives to improve the fuel properties of palm biodiesel and engine performance. The review shows that the additive usage in palm biodiesel is accompanying for improving the cold flow properties and better engine performance as well emission regulation.

Abstract:

Biodiesel plays a major role as one of the alternative fuel options in direct injection diesel engines for more than a decade. Though many feed stocks are employed for making biodiesel worldwide, biodiesel derived from domestically available non-edible feed stocks such as Jatropha curcas L. is the most promising alternative engine fuel option especially in developing countries. Since experimental analysis of the engine is pricey as well as more time consuming and laborious, a theoretical thermodynamic model is necessary to analyze the performance characteristics of jatropha biodiesel fueled diesel engine. There were many experimental studies of jatropha biodiesel fueled diesel engine reported in the literature, yet theoretical study of this biodiesel run diesel engine is scarce. This work presents a theoretical thermodynamic study of single cylinder four stroke direct injection diesel engine fueled with biodiesel derived from jatropha oil. The two zone thermodynamic model developed in the present study computes the in-cylinder pressure and temperature histories in addition to various performance parameters. The results of the model are validated with experimental values for a reasonable agreement. The variation of cylinder pressure with crank angle for various models are also compared and presented. The effects of injection timing, relative air fuel ratio and compression ratio on the engine performance characteristics for diesel and jatropha biodiesel fuels are then investigated and presented in the paper.

Abstract:

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:

Recent trends to downsize diesel engines have increased the stress on lubricants. Oils naturally degrade during operation, undergoing continual reactions, changing chemically and physically, detracting in performance from initial specifications. This thesis investigates the role of fuel in the ageing of diesel engine oils, specifically Ultra Low Sulphur Diesel (ULSD) and Rapeseed Methyl Ester (RME – a common European biodiesel). Oil ageing is assessed distinctly with fuel dilution, the entrainment of exhaust gases; and the effects of soot loading. Results show fuel dilution has the greatest influence on oil performance. Effects are seen with an instant ‘dilution’ of properties, with the resultant blend performing as an amalgam of the fluids. This can be both positive and negative, depending on the property being measured, with the entrainment of biodiesel generally beneficial. The entrainment of exhaust gases in the oil leads to increased unburnt hydrocarbons and fuel content, with similar dilution effects. Soot loaded oil performance is heavily dependent on the respective fuel content. RME contamination has a positive influence which far outweighs its negligible soot production, whereas ULSD detracts from oil performance, also producing more soot. During an equivalent timeframe, the influence of RME is less detrimental than ULSD on overall performance.

Abstract:

An experimental investigation of the effects of fuel composition on the ignition delay and heat release characteristics of a light duty, automotive compression ignition engine has been carried out. The ignition delay is defined as the period between the start of the main fuel injection event and the start of combustion (SOC). The research has covered a range of fuel types and blends to maximise the effects of composition on the ignition delay and heat release. The fuels used were diesel, gasoline and FAME (Fatty Acid Methyl Esters) produced from rapeseed oil, coconut oil and waste cooking oil. All the engine test studies were carried out using a 2.4 litre displacement, direct injection Ford Puma engine, at test conditions representing low load, mid load and high load at 2000rpm, with EGR rates of up to 35%. Single equation, semi-empirical ignition delay models based upon the Arrhenius equation were studied and developed to fit the experimental ignition delay data, and thus incorporate fuel composition effects. Fuel composition is shown to affect the duration of the ignition delay, but after the start of combustion the heat release characteristics, for a given energy supplied in fuel, proved to be relatively insensitive to fuel composition effects. The premixed fraction is shown to be directly proportional to the ignition delay. The ignition delay of biodiesel fuel is up to 15% shorter than diesel while a gasoline blend of 50% gasoline/50% diesel lengthens the ignition delay by up to 30% with respect to diesel. These differences in the ignition delay affect the engine thermal efficiency by up to 2% due to combustion phasing effects. Gasoline fuel blended up to 80% (by volume) with diesel was combusted successfully, resembling PCCI (Premixed Charged Compression Ignition) combustion regimes, while biodiesel fuel types RME (Rapeseed Methyl Esters), CME (Coconut Methyl Esters) and WCO (Waste Cooking Oil Methyl Esters) all showed differences in heat release characteristics due to ignition delay differences. Calibration changes are necessary to compensate for the fuel composition effects on the ignition delay and subsequent combustion characteristics. An engine specific, single equation ignition delay model was developed that successfully described the experimental ignition delay data over the fuel range of fuel composition: rID = 4.32p-l.02/'P-O.2exp (:;) where EA = A.Kevric University of Nottingham , ' )t8186 . Based upon the analysis of combustion characteristics of the experimental CN+ZS) data, the initial form of a universal ignition delay model was developed, composing of a physical delay portion and a chemical delay portion.

Abstract:

Biodiesels have been proved to reduce the smoke and THC emissions by many researchers. The demands of biodiesel are increasing all over the world. Various feedstocks of biodiesel have been used in different countries and regions. The blend ratio of biodiesel in petrol station is also varies. Therefore, more calibration works have been done for the car manufacturers. In first part this research, the combustion characteristics and emissions of using biodiesels from different feedstocks with different blend ratio was studied by experimental works. Statistical analysis indicated the correlation between emissions and fuel properties. Then, a smoke index, containing Reynolds Number of fuel spray, cetane number and gross heat value of combustion, was created and showed a significant linear relationship with the smoke emissions. The effects of engine loads and EGR rates on the relationship were also discussed. The second part of this research was focused on the cold start with using biodiesel blends. The tests were conducted in a wide range of the temperatures (from -20°C to 90°C). Results showed that the methyl ester biodiesel reduced the PM during the acceleration period of the start at 20°C conditions. As ambient temperature decreased, using of biodiesel shows an increased emissions of PM and THC. The chemical compositions of particle emissions with using biodiesel blends at cold start were identified by a 20-GC/MS and the results also confirmed this trend.

Abstract:

There has been considerable interest in recent years in using blends of petroleum diesel and biodiesels in diesel engines. Some of the interests arise in making use of renewable fuels, or in reducing dependency on imported fossil fuels and, in some cases, to provide economic boost to agricultural industry. It is believed that substitution of a small amount of biodiesel for petroleum diesel can reduce the import of fuel and help in trade balance. Biodiesels, whether derived from vegetable oils or animal fat, have many properties that align with those of petroleum diesel. This makes biodiesel a good candidate for blending it in small quantities with petroleum diesel. Studies have shown biodiesel blends to work well in diesel engines. However, experimental investigations of biodiesel blends have shown some discrepancies in engine thermal efficiency and emissions of NOx. A combustion simulation model for diesel engine may help to understand some of the differences in engine performance when different fuels are used. This paper deals with an existing simulation model that was applied to a diesel engine operating on biodiesel blends. The model was a modified version of GT-Power that was specifically modified to fit the test engine. The model was calibrated using a single cylinder, naturally aspirated, DI diesel engine operating on ultra-low sulfur (ULSD) diesel. It was used to predict engine performance when operating on different blends of soy biodiesel and ULSD. The simulation utilized detailed physical and chemical properties of the blends to predict cylinder pressures, fuel consumption, and emissions of oxides of nitrogen (NOx). Comparison between predicted and experimental values showed good correlations. The predicted trends in fuel consumption, emissions of NOx and smoke showed comparable trends. The model allows the user to change fuel properties to assess the impact of variations in blend composition on exhaust emissions. This paper discusses comparisons between the predicted and experimental results and how fuel composition can possibly impact NOx emissions.

Abstract:

A single cylinder DI (direct injection) diesel engine equipped with common-rail injection system was used to investigate the combustion and emission characteristics of biodiesel fuels. Tested fuels were conventional diesel and biodiesels obtained from unpolished rice oil and soybean oil. The volumetric blending ratios of biodiesel with diesel fuel are set at 0, 10, 20 and 40%. Experimental results show that the peak injection rate is reduced as the mixing ratio increased. The effect of the mixing ratio on the injection delay of biodiesel is not significant at the equal injection pressure. The peak combustion pressure was increased with the increase of the mixing ratio at an injection pressure of 100MPa. The ignition delay became shorter with the increase of the mixing ratio due to a higher cetane number of the biodiesel. HC and CO emissions are decreased at a high injection pressure. However, NOx emissions are increased at higher mixing ratios.

Abstract:

This paper presents emissions modeling and testing of a four-stroke single cylinder diesel engine using pure soybean, cottonseed, and algae biodiesel fuels. A system level engine simulation tool developed by Gamma Technologies, GT-Power, has been used to perform predictive engine combustion simulations using direct-injection jet modeling technique. Various physical and thermodynamic properties of the biodiesel fuels in both liquid and vapor states are required by the GT-Power combustion simulations. However, many of these fuel properties either do not exist or are not available in published literatures. The properties of the individual fatty esters, that comprise a biofuel, determine the overall fuel properties of the biofuel. In this study, fatty acid profiles of the soybean, cottonseed, and algae methylester biodiesel fuels have been identified and used for fuel property calculations. The predicted thermo-physical properties of biodiesels were then provided as fuel property inputs in the biodiesel combustion simulations. Using the calculated biodiesel fuel properties and an assumed fuel injector sac pressure profile, engine emissions of the conventional diesel and biodiesel fuels have been predicted from combustion simulations to investigate emission impacts of the biodiesel fuels. Soybean biodiesel engine emissions, which include NOx, HC, CO and CO2, measured at various engine speeds and loads in actual combustion emissions tests performed in this study were also compared to those predicted by the combustion simulations.

Abstract:

Biodiesels derived from vegetable oils present a very promising alternative fuels for diesel fuel, since they have numerous advantages compared to fossil fuels. However crude vegetable oil and biodiesel have high viscosity and low volatility causing combustion problems in CI engines, call for engine with hot combustion chamber. Investigations were carried out on single–cylinder, four–stroke, water cooled, 3.68 kW direct injection diesel engine at a speed of 1500 rpm to evaluate the performance of a engine with low heat rejection (LHR) combustion chamber. It consisted of an air gap (3 mm) insulated piston with superni (an alloy of nickel) crown and an air gap (3 mm) insulated liner with superni insert and ceramic coated cylinder head fuelled with different operating conditions (normal temperature and preheated temperature) of waste fried vegetable oil and its biodiesel with varied injection timing and injector opening pressure. Engine with LHR combustion chamber with biodiesel showed improved performance over conventional engine (CE) at 27° bTDC and at optimum injection timing. Biodiesel showed improved performance over crude vegetable oil with engine with both versions of the combustion chamber. Preheated test fuels and increase of injection pressure showed reduction of pollution levels and marginally improved performance over normal test fuels.

Abstract:

Diesel engine emissions are a source of environmental concern. The use of vegetable oil based fuels, called biodiesels, lowers particulate emissions due to the increased oxygen content of the fuel. This study aims to further increase the oxygen content of biodiesel by oxidizing the fuel, analyzing the resulting product, and determining if favorable lubricity qualities result. Oxidation is performed in a non-catalytic vapor phase reactor at temperatures between 300–400°C. The product is characterized using various analyses including sulfuric acid solubility, density, gas chromatography, bomb calorimetry, and lubricity. Optimum blend ratios of the oxidized fuels in a low sulfur diesel fuel to obtain maximum lubricity are determined.

Abstract:

This paper emphasizes on the effects of different biodiesels and diesel on; heat release, ignition delay, endothermic and exothermic reactions, NOx, fuel injection pressure due to the fuel’s modulus of elasticity and cylinder pressure. Two 100% biodiesel and its blends of 20% with of low sulfur #2 diesel, and #2 diesel are tested on a single cylinder diesel engine under full load condition. Engine performance and emissions data is obtained for 100% and 20% biodiesels blends and #2 diesel. Testes were conducted at Engine Systems Development Centre, Inc. (ESDC) to evaluate the effects of biodiesel and its blends on the performance and emissions of a single-cylinder medium-speed diesel engine. The main objective of this work was to gain initial information and experience about biodiesel for railway application based on which biodiesel and its blends could be recommended for further investigation on actual locomotives.

Abstract:

This study investigated experimentally the performance of turbojet engine fueled by biodiesel obtained from different feedstocks. The engine is equipped with measuring sensors for pressure, temperature, thrust, shaft speed in addition to flow meter, data acquisition system and a control unit. The results of the effect of biodiesel fuel type and its blends on turbojet engine performance are presented. Three biodiesel fuels which are Cotton methyl ester (CTME), Corn methyl ester (CRME) and Sunflower methyl ester (SME) and their blends of B10, B20 and B50 (10%, 20% and 50% biodiesel/Jet A1 by volume) are used and compared with the engine recommended fuel (Jet A1). Moreover, in this study, the Biodiesel fuel is produced through transesterification process in which the triglyceride (oil) reacts with alcohol (methanol) to form the mono-alkyl ester (biodiesel) and glycerol. Physical and chemical properties of all produced and tested fuels are measured. The results clearly indicate that the produced biodiesel fuels have a higher density, kinematic viscosity, than JetA-1 fuel, while, the calorific value of biodiesel fuels is very close to JetA-1 fuel. Moreover, JetA-1 fuel has higher sulfur content than other biodiesel fuels. Also, the experimental results show that Engine speed for the cases of using biodiesel fuels is lower than JetA-1 fuel at the same fuel throttle valve opening. Moreover, the Biodiesel fuels have a lower fuel volume flow rate compared to JetA-1 at the same throttle valve opening that lead to decrease the engine static thrust as well as lower value of TSFC.

Abstract:

The enhanced use of diesel fuel and the strict emission norms for the protection of environment have necessitated finding sustainable alternative and relatively green fuels for compression ignition engines. This paper presents a brief review on the current status of biodiesel production and its performance and emission characteristics as compression ignition engine fuel. This study is based on the reports on biodiesel fuels published in the current literature by different researchers. Biodiesel can be produced from crude vegetable oil, non-edible oil, waste frying oil, animal tallow and also from algae by a chemical process called transesterification. Biodiesel is also called methyl or ethyl ester of the corresponding feed stocks from which it has been produced. Biodiesel is completely miscible with diesel oil, thus allowing the use of blends of mineral diesel and biodiesel in any percentage. Presently, biodiesel is blended with mineral diesel and used commercially as fuel in many countries. Biodiesel fueled CI engines perform more or less in the same way as that fueled with the mineral diesel. Exhaust emissions are significantly improved due the use of biodiesel or blends of biodiesel and mineral diesel. The oxides of nitrogen are found to be greater in exhaust in case of biodiesel compared to mineral diesel. But the higher viscosity of biodiesel also enhances the lubricating property. Biodiesel being an oxygenated fuel improves combustion.

Abstract:

Increasing concerns over pollutant emissions from diesel engines have prompted researchers to find replacement fuels for diesel engines. The use of alternative fuels such as biodiesel in compression-ignition (CI) engines is beneficial to the environment as it reduces emissions of pollutants with slight penalty on the performance. This paper investigated the use of biodiesel fuel (rapeseed oil) in a CI engine by numerical simulations. The numerical simulations were based on the models of finite heat release, cylinder heat transfer, and friction losses. Simulations were carried out to evaluate the effects of compression ratio, equivalence ratio, and engine speed on the performance of the CI engine. The results of the simulations were compared with experimental data from the literature to validate the simulations. Good agreements between the computed and experimental results were obtained. The results showed that the current model could satisfactorily predict the performance of a biodiesel-fueled CI engine.

Abstract:

To reduce the dependency on fossil-based energy resources, the utilization of renewable fuels in unmodified diesel engines is gaining more emphasis from researchers in the recent years. The aim of the current study is to take part in the efforts being made to this regard by experimentally investigating a compression ignition engine fueled with different fuels ((diesel, diesel-biodiesel (B20), and diesel-biodiesel-butanol (BU20)) for their performance and emissions comparison. The experimental study was conducted in a water cooled single-cylinder direct injection (DI) diesel engine. It was operated at a constant engine operation speed of 1800 rpm and under varied engine load conditions. It is found that BU20 shows promising results in terms of performance and emissions characteristics as compared to using B20 and D100. Butanol addition to diesel-biodiesel blends is considered as an appropriate solution of higher density and viscosity the blend and thus for the sustainable usability of biodiesel. Maximum thermal efficiency improvement of 3.18% was observed at an engine load of 75%. The NOx emission was improved with BU20 as compared to the conventional diesel fuel (D100) at most of the engine loads. As an improvement on the engine performance and emissions is reported from the current study, the BU20 fuel blends can be used in similar engines with no further engine retrofitting. This blend can be a good environmental friendly fuel that can serve in the reduction of fossil-based diesel fuels. A further study on diesel engine tribology is required.
