Rapeseed Oil Esters as Diesel Engine Fuel

Energy Sources, Part A: Recovery, Utilization, and Environmenta

2012

In this study, an alternative diesel fuel, of which chemical modification was made by transesterification with short chain methyl alcohols, was produced from cottonseed oil. The modified products were then evaluated according to their fuel chemical properties as compared to diesel fuel. The purpose of this study is to investigate the emission characteristics of the fuel blend of 75% cottonseed oil methyl ester with 25% diesel fuel in a single cylinder unmodified diesel engine. The effects of biofuel and diesel fuel blend on a direct injected, four strokes, and single cylinder diesel engine exhaust emissions were studied. The results showed on the emissions of the engine that there was about 36% reduction in CO, about 18% reduction in CO 2 , and about 15% reduction in NOx. These results show that B75 fuel has better emission characteristics than diesel fuel. The reduction exhaust emissions made B75 a suitable alternative fuel for diesel engines and could help in controlling air pollution.

“…Vegetable oils can be used as a material to produce methyl or ethyl ester. There are several methods for producing ester; and the best method is known as transesterification (Freedman et al, 1986;Mittelbach and Enzelsberger, 1999;Schuchardt et al, 1998;Ramadhas et al, 2005;İlkılıç and Yucesu, 2005;Megahed et al, 2004;Dorado et al, 2004;Encinar et al, 2002;Noureddini and Zhu, 1997;Ma and Hanna, 1999;Harrington and D'Arcy-Evans, 1985).…”

In this study, an alternative diesel fuel, of which chemical modification was made by transesterification with short chain methyl alcohols, was produced from sunflower oil. The modified products were then evaluated according to their fuel properties as compared to diesel fuel. The fuel properties considered were viscosity, pour point, calorific value, flash point, and cetane number in addition to some other properties. The effects of biodiesel and diesel fuel on a direct injected, four stroke, single cylinder diesel engine exhaust emissions were studied. The results showed on the emissions of the engine that there were about 30% reduction in CO, about 26% reduction in CO 2 , and about 25% reduction in NOx. The reduction exhaust emissions made the biodiesel a suitable alternative fuel for diesel engine and could help in controlling air pollution.

“…Moreover, when it was used in an IC engine, CO 2 , SO 2 , and UHC (unburned hydrocarbon) emissions were reduced. Biodiesel can be used with petroleum-based diesel fuel as blends (Megahed et al, 2004). The viscosity and density of biodiesel were close to those of diesel fuel.…”

An Analysis of Exhaust Emissions on a Diesel Engine Operation by Biodiesel

Energy Sources, Part A: Recovery, Utilization, and Environmenta

Vegetable oils can be seen as a renewable fuel source for diesel engines. However, their viscosity is higher than that of diesel fuel. The higher viscosity of vegetable oil causes many combustion problems when directly used in diesel engines. In this study, a transesterification method was used to reduce the viscosity of the vegetable oil. Emission characteristics of both biodiesel and diesel fuels were experimentally investigated in an unmodified diesel engine. The test results have shown that the emissions of biodiesel were fairly low as compared to diesel fuel. CO and CO 2 emissions of biodiesel were decreased respectively about 56 and 17% in comparison to diesel fuel.
