Biodiesel is usually produced from food-grade vegetable oils that are more expensive than diesel fuel. Therefore, biodiesel produced from food-grade vegetable oil is currently not economically feasible. Waste cooking oils, restaurant grease and animal fats are potential feedstocks for biodiesel. These inexpensive feedstocks represent one-third of the US(More)
Keywords: ANN Biodiesel Diesel engine Engine performance Emissions a b s t r a c t Biodiesel is receiving increasing attention each passing day because of its fuel properties and compatibility with the petroleum-based diesel fuel (PBDF). Therefore, in this study, the prediction of the engine performance and exhaust emissions is carried out for five(More)

In this study, corn oil as vegetable oil, chicken fat and fleshing oil as animal fats were used to produce methyl ester in a biodiesel pilot plant. The FFA level of the corn oil was below 1% while those of animal fats were too high to produce biodiesel via base catalyst. Therefore, it was needed to perform pretreatment reaction for the animal fats. For this(More)
In this study, the effects of two stage direct injection (TSDI) strategy were investigated on the combustion and performance of an engine fueled with ethanol-gasoline blends. A diesel engine was converted to an electronically controlled HCCI engine. For each injection the injection timings and fuel quantity were adjusted to get desired mixture formation in(More)
