Full textThe high cost of fossil fuels and the fact that the world has arguably reached its peak oil production, has driven the need to seek alternative fuel sources. The main objective of the current study is to determine the performance of a laboratory-mounted diesel engine when fuelled with varying laboratory prepared biofuel and biodiesel and whether the advancement of the injection timing parameters will improve the engine power output and improve the smoke effect of these different fuel blends. The laboratory prepared biofuels used in this project range from 100% bio-fuel (BF100) to 50%, 30% and 10% biodiesel blends (BF50, BF30 and BF10, respectively). It should be noted that these blends are not commercially available, since they were blended in the laboratory specifically for these tests. The overall results of the study show that there is a distinct opportunity for using certain bio-fuel blends in specific applications as the power outputs are no more than one quarter less than that of base diesel. Concomitantly, the smoke opacity in all of the blends is lower than that of base diesel, which is a significant benefit in terms of their overall air emissions.

Full textThe industry, over the years, has been working to improve the efficiency of diesel engines. More recently, it was observed the need to reduce pollutant emissions to conform to the stringent environmental regulations. This has attached a great interest to develop researches in order to replace the petroleum-based fuels by several types of less polluting fuels, such as blends of diesel oil with vegetable oil esters and diesel fuel with vegetable oils and alcohol, emulsions, and also microemulsions. The main objective of this work was the development of microemulsion systems using nonionic surfactants that belong to the Nonylphenols ethoxylated group and Lauric ethoxylated alcohol group, ethanol/diesel blends, and diesel/biodiesel blends for use in diesel engines. First, in order to select the microemulsion systems, ternary phase diagrams of the used blends were obtained. The systems were composed by: nonionic surfactants, water as polar phase, and diesel fuel or diesel/biodiesel blends as apolar phase. The microemulsion systems and blends, which represent the studied fuels, were characterized by density, viscosity, cetane number and flash point. It was also evaluated the effect of temperature in the stability of microemulsion systems, the performance of the engine, and the emissions of carbon monoxide, nitrogen oxides, unburned hydrocarbons, and smoke for all studied blends. Tests of specific fuel consumption as a function of engine power were accomplished in a cycle diesel engine on a dynamometer bench and the emissions were evaluated using a GreenLine 8000 analyzer. The obtained results showed a slight increase in fuel consumption when microemulsion systems and diesel/biodiesel blends were burned, but it was observed a reduction in the emission of nitrogen oxides, unburned hydrocarbons, smoke index and f sulfur oxides

Os sistemas microemulsionados e as misturas, que representam os combust?veis estudados, foram caracterizados quanto ? massa espec?fica, a viscosidade, o ?ndice de cetano e o ponto de fulgor. Tamb?m foram avaliados o efeito da temperatura nos sistemas microemulsionados, o desempenho do motor, e as emiss?es de mon?xido de carbono, ?xidos de nitrog?nio, hidrocarbonetos n?o queimados e fuma?a de todos os sistemas.

Full textThe growing demand of energy in the world, the decrease of petroleum reserves and the current problems of environmental contamination, increase the interest in renewable energy study for internal combustion engines, to replace partially or completely to petroleum based fuels. In Brazil, among the alternatives fuels, stands out the use of sugarcane ethanol, seen that it is from renewable sources and has high oxygen content, which is favorable to reduce pollutant gases emissions of engine. The blend of ethanol and diesel (ED) has received in recent years and in different countries, more attention for use in diesel engines. However, there are difficulties to partially replace diesel use. The main disadvantages are the differences in their physical-chemical properties. A percentage up to 15% of ethanol is used in diesel engines without making mechanical changes. In this way, the objective of this study was to evaluate the performance and emissions of a diesel engine in an agricultural tractor, using blends of diesel and hydrated ethanol. Were used as fuel, Diesel (B5) and mixture with 3% (ED3), 6% (ED6), 9% (ED9), 12% (ED12) and 15% (ED15) of hydrous ethanol. Performance parameters evaluated were the power, torque and specific fuel consumption. Were also evaluated emissions of CO2, NOx e O2, and the opacity of the gases through the k value. Both, engine performance and emissions experiment were analyzed in a completely randomized with bifactorial design. The results indicate that as the percentage of ethanol increased, the average values of torque and engine power decreased. Using the B5 and the ED3, these variables did not differ statistically, in addition, with the ED3 was obtained the lower specific fuel consumption. Using ED12, the engine performance has reduced power and torque in 2.97% e 2.95%, respectively, compared with B5, while their fuel consumption had no statistical difference. The greater opacity and gas emissions were archive with ED3, while the lower emission occurred when the engine operated with ED12 and ED15. With these fuels, the reduction of opacity, CO2 and NOX, in relation to B5, was 22.22 24.44%, 5.20 5.60% e 6.65 - 10.48%, respectively. It can be considerate that operating with ED12, pollutant emissions are reduced significantly without a significant loss in engine performance.
A crescente demanda mundial de energia, a diminuição das reservas do petróleo e os atuais problemas de poluição ambiental, incrementam o interesse no estudo de fontes renováveis de energia para os motores de combustão interna, visando substituir, de forma parcial ou total, os combustíveis derivados do petróleo. No Brasil, entre os combustíveis alternativos, se destaca o uso do etanol de cana-de-açúcar, visto que é de origem renovável e possui um alto conteúdo de oxigênio, o qual pode favorecer a redução das emissões de gases poluentes do motor. A mistura etanol- Diesel (ED) vem recebendo, nos últimos anos, e em diferentes países, maior atenção para ser utilizado em motores ciclo Diesel. No entanto, existem dificuldades para sua utilização visando substituir parcialmente o óleo Diesel. Os principais inconvenientes são as diferenças nas suas propriedades físico-químicas. Em porcentagens de até 15%, o etanol pode ser utilizado em motores ciclo Diesel, sem realizar modificações mecânicas. Desta forma, o objetivo deste trabalho foi avaliar o desempenho e as emissões de um motor ciclo Diesel de um trator agrícola, utilizando misturas de óleo Diesel e etanol hidratado. Foram utilizados como combustíveis o óleo Diesel (B5) e sua mistura com 3% (ED3), 6% (ED6), 9% (ED9), 12% (ED12) e 15% (ED15) de etanol. Os parâmetros avaliados de desempenho foram: a potência, o torque e consumo específico de combustível. Foram também avaliadas as emissões de CO2, NOx, O2 e a opacidade dos gases, por meio do valor k. Ambos os experimentos de desempenho e emissões do motor foram analisados em um delineamento experimental inteiramente casualizado, em um esquema bi fatorial. Os resultados indicam que conforme aumentou a porcentagem de etanol, os valores médios de torque e potência do motor diminuíram. Utilizando o B5 e o ED3, estas variáveis não diferiram estatisticamente, além disso, com o ED3 foi obtido o menor consumo de combustível. Utilizando o ED12 o desempenho do motor teve reduções de potência e torque de 2,97% e 2,95%, respectivamente, em relação ao B5, enquanto que os consumos de combustível não tiveram diferença estatística. A maior opacidade e emissões de gases foram alcançadas com ED3, enquanto que as menores emissões ocorreram quando o motor operou com o ED12 e ED15. Com estes combustíveis, a redução da opacidade, CO2 e NOx, em relação ao B5 foi de 22,22 - 24,44%, 5,20 - 5,60% e 6,65 - 10,48%, respectivamente. Pode-se considerar que operando com o ED12, as emissões de poluentes são reduzidas significativamente sem uma perda considerável no desempenho do motor.

Full textIt was developed a supplementary fueling system for turbocharged compression ignition, which uses diesel injected usually in the combustion chamber and post-vaporized ethanol, that is injected in the liquid state inside the intake manifold and vaporized by the energy in the compressed air. It was possible to replace up to 55% of the diesel mass by ethanol; regular and repetitive operation was verified, result of the alcohol induction in the vapor state. It was verified that engine\'s efficiency and pollutant gases emissions were quite influenced by the fueling system developed: improvements of up to 25,6% in the efficiency were possible, with maximum reductions of 81% in particulate matter and 80% in NOx, as a result of a more efficient diesel oxidation in presence of ethanol vapor. Notable reductions in the compressed air temperature were reached, making possible the substitution of the \"intercoolers\". The theoretical analysis to implantation of the developed system, on vehicles of public transportation in the metropolitan area of São Paulo, indicated economical and environmental viability.

Full textThe increasing levels of pollution in urban centers have induced the adoption of mitigating measures in order to reduce negative consequences. In Curitiba, Southern Brazil, the office that regulates urban passenger transport in the city has promoted the use of pure biodiesel (B100) as fuel for a fleet of 34 buses. However, as this measure was put into practice, concerns related to a possible reduction of engine service life were raised, thus forcing the vehicles-owner companies to adopt a conservative maintenance plan, which doubled the frequency of lubricant oil replacement. This was the opportunity for the present study, which aimed to define on a scientific basis the frequency of lubricant oil replacement in engines fueled with biodiesel B100. In order to characterize both the evolution of lubricant oil degradation, as well as the deterioration of lubricant performance due to the use of biodiesel B100, samples of engine lubricant were collected and analyzed along 18 months. Additionally, aiming to confer statistical representativeness to collected data, a population of 7 buses was considered, four of these being fueled with biodiesel B100, while the other 3 with conventional diesel fuel, thus the latter group served as a reference for comparisons. The following parameters of the lubricant oil were measured and analyzed: viscosity, basicity, acidity, oxidation, contamination by soot, contamination by nitrogenous substances, contamination by water, as well as contents of iron, lead, aluminum, copper, chrome, silicon and molybdenum, which are elements typically originated from the wear of metallic components. The conducted study allowed to point out the viscosity as the lubricant parameter that is most sensitive to concomitant use with biodiesel B100. Thus, this parameter was decisive to conclude that based on measured data the service life of the lubricant should be 9900 km for bi-articulated buses, and 13100 km for the articulated ones. It is worth mentioning that the completion of this study became possible by virtue of the collaboration with those companies that took part of the project named LUB-B100, together with the Federal University of Technology - Parana. These companies are Chevron Brasil Lubrificantes (a lubricant maker company), Volvo do Brasil (a bus manufacturer company), Auto Viação Redentor (a company that operates the passenger urban transport in Curitiba), Nórdica Veículos S. A. (a Volvo dealership company) and URBS – Urbanização de Curitiba S. A. (the office that regulates the urban passenger transport in Curitiba).

Full textBiodiesel, produced from the transesterification of vegetable oils or animal fats with simple alcohol in the presence of a catalyst, is well positioned to replace petroleum-based diesel. Biodiesel is a non-toxic, biodegradable and renewable fuel. Despite its advantages, the chemical nature of biodiesel makes it more susceptible to oxidation compared to mineral diesel during long-term storage. The production of Croton Oil Methyl Ester (COME), Moringa Oil Methyl Ester (MOME) and Jatropha Oil Methyl Ester (JOME) was therefore carried out. Also, a determination of the fuel related properties and investigation of oxidation stability of the methyl esters produced without and with antioxidants and its blends with mineral diesel were conducted. The results showed that most of the measured fuel related properties of produced methyl esters fulfilled the minimum requirements of EN 14214 and ASTM 6751 biodiesel standards. However, COME and MOME did not meet EN 14214 oxidation stability standards (6 h) while JOME displayed very high oxidation stability (10.43 h) well within specified oxidation stability standards. Overall, the biodiesel derived from non-edible oils of African origin such as COME, MOME and JOME can be utilized as a partial substitute for mineral diesel. This study recommends that PY and PG antioxidants be used for safeguarding biodiesel fuel from the effects of autoxidation during storage.
