• Abstract

As a renewable and alternative fuel for compression ignition engines, biodiesel instead of diesel has been increasingly fuelled. In the recent 10 years many researchers investigated the effects on engine performances and emissions which are the harmful in diesel engine. Around the world researched are devoted to reduce such emissions with different ways like fuel modification, combustion chamber design and treating the exhaust gas, etc., In this connection the hunt for the suitable alternative fuels for diesel engine initiated. In this study the performance and emission characteristics of the direct injection diesel engine fuelled with different biodiesel published in high rated journals are to be analyzed and compared. The performance parameters includes thermal efficiency & specific fuel consumption and the exhaust emissions includes unburnt hydrocarbons (HC), carbon monoxide (CO), carbon dioxide(CO2), and nitrogen oxides(NOx). A report will be framed indicating the increase and decrease in the performance and emission characteristics and the reasons for the change will be identified. The best combinations which will give reducing the emissions and increasing the performance characteristics are tabulated.

Keywords: Alternative fuel, Combustion Chamber, Emission characteristics, Performance, Exhaust gas recirculation, Cetane improver.
