Abstract—Biodiesel is defined as the mono alkyl esters of long chain fatty acids derived from renewable lipid sources. It is a term used to describe a methyl or ethyl ester made from vegetable oils, animal fats, and used cooking oils and fats. It is oxygenated, non-toxic, sulphur-free, biodegradable and renewable fuel. The scarcity and increase in the crude oil prices have forced everyone to think on the use of biodiesel as an alternative fuel source. Also, it is important that unlike the traditional fuels which emit green house gases and particulate matter, the biodiesel is greener and hence less polluting. More than 350 oil-bearing crops identified, among which some only considered as potential alternative fuels for diesel engines. The focus of this study is to review the effect of using B-20 (a blend of 20% biodiesel and 80% diesel fuel) on engine performance and exhaust emissions in a CI engine.
