Gasoline Fuel Blends for Otto Engines and Gasoline Fuel Additives

Abstract: Gasoline is a volatile mixture of flammable liquid hydrocarbons derived chiefly from crude petroleum, which is used principally as a fuel for internal-combustion engines. Gasoline is a blend of hydrocarbons with some contaminants, including sulfur, nitrogen, oxygen, and certain metals. Methanol and ethanol as alcohol fuels are technically and economically suitable for internal combustion engines. The octane number of gasoline increases continuously and linearly with methanol and ethanol percentages in gasoline. Hence, methanol is an effective compound for increasing the value of the octane number of gasoline. The engine performance improves as the percentages of methanol and ethanol increase in the blend. Fuel additives are used to improve gasoline performance in vehicles and to reduce specific emissions. They include octane enhancers, antiknock compounds, and oxygenates, as well as corrosion inhibitors, detergents, and dyes.

간접분사식 디젤기관에서 바이오디젤유 및 egr 방법 적용

Abstract: In this study, the potential possibility of biodiesel fuel was investigated as an alternative fuel for a naturally aspirated indirect injection diesel engine. The smoke emission of biodiesel fuel was reduced remarkably in comparison with diesel fuel, that is, it was reduced approximately 36% at 2000rpm, full load condition. And, power, torque and brake specific energy consumption showed no significant differences. However, NOx emission of biodiesel fuel was increased compared with commercial diesel fuel. Also, the effects of exhaust gas recirculation(EGR) to reduce the NOx emission has been investigated. It was found that simultaneous reduction of smoke and NOx was achieved with biodiesel fuel(20vol-%) and cooled EGR method(10~15%).

Ammonia and Gasoline Fuel Blends for Internal Combustion Engines

Abstract: Ammonia, when blended with hydro carbon fuels, can be used as a composite fuel to power existing IC engines. Such blends, similar to ethanol and gasoline fuel blends, can be used to commercialize ammonia as an alternative fuel. Feasibility of developing ammonia gasoline liquid fuel blends and the use of ethanol as an emulsifier to enhance the solubility of ammonia in gasoline were studied using a small thermostated vapor liquid equilibrium (VLE) high pressure cell in this research. A larger VLE cell was used to develop identified fuel blends in sufficient quantities for engine dynamo-meter tests. A engine dynamometer equipped with a 2.4L gasoline engine was used to benchmark performance of ammonia fuel blends against standard fuels. Solubility test results proved that ethanol free gasoline is capable of dissolving 4.5% of ammonia on volume basis (23 g/l on mass basis) at 50 psi [344.7 kPa] pressure and 286.65 K temperature in liquid phase. Solubility levels are increased with the use of ethanol. Gasoline with 30% ethanol can retain 18% of ammonia in the liquid phase by volume basis (105 g/l by mass basis) at the same pressure and temperature. Dynamometer results show the ability of new composite fuel blends to produce the same amount of torque and power in the lower rpm limits. At higher rpm levels ammonia rich fuels result in an increased torque and power. Thus it can be concluded that hydrogen energy can be stored as ammonia-gasoline fuel blends and recovered back successfully without any strenuous modification to the existing infrastructure and end user equipment or behavior.Copyright © 2014 by ASME

Ammonia Gasoline-Ethanol/Methanol Tertiary Fuel Blends as an Alternate Automotive Fuel

Abstract: Ammonia and hydrocarbon fuel blends, similar to ethanol and gasoline fuel blends can be used to commercialize ammonia as an alternative fuel. Feasibility of developing ammonia gasoline liquid fuel blends and the use of ethanol and methanol as emulsifiers to enhance the solubility of ammonia in gasoline were studied using thermostated vapor liquid equilibrium (VLE) high pressure cells, in this research. Solubility test results prove that emulsifier free pure gasoline is capable of dissolving 23 g/l of ammonia on mass basis (4.5% of ammonia on volume basis) at 345 kPa pressure and 286.65 K temperature in liquid phase. Solubility level is increased with the use of ethanol and methanol. Gasoline with 10% ethanol can retain 31.7 g/l (5.7% on volume basis) of ammonia in the liquid phase at the same pressure and temperature. Methanol has better emulsifying capabilities. Solubility level of gasoline with 30% methanol is 189.5 g/l (30.0% on volume basis). This paper presents solubility and dynamometer test results of five fuel blends E/M0, E10, M10, M20 and M30. Better performances are observed when the ammonia rich fuels are benchmarked against baseline fuel especially at higher engine speeds.Copyright © 2014 by ASME
