To Study the Impact of Emissions of Methyl Esters Blends in Diesel Engine

Abstract

Nowadays the world faces energy crisis due to depletion of resources and increased environmental problems. World’s need of energy is supported by non renewable and some renewable energy sources such as natural gases, diesel fuel, petrol fuel and nuclear energy and hydroelectricity. The non-renewable energy sources will be exhausted very soon. This may be due to rapid growth in population and financial developments. So that petroleum prizes are increasing day by day. Continued and increasing utilization of such fuels resulted in higher air pollution. Therefore, there is an immediate requirement and the researchers are working hard to find a new energy resource that is of biological resource, reliable and most important is that should be cheap as a substitute to the current diesel fuel. In this regard, recently, biodiesel derived from vegetable oil has been shown to be a viable substitute to running diesel fuel (B00%) for diesel engines and is receiving worldwide attention because of its ecofriendly nature, carbon neutrality and non toxicity. Biodiesel fuel is supporting to reduce exhaust gases. This paper deals with the application of pongamia and jatropha methyl esters in diesel engine. Both the methyl esters were synthesized by acid esterification followed by a heterogeneous catalyzed transesterification reaction method. The blends such as B10%, B20%, B30% were prepared separately from each of methyl ester of jatropha and pongamia respectively. The B00% i.e. diesel fuel was considered as a standard fuel. All the fuel blends including B00% were run in a single cylinder diesel engine at various loads (such as 0, 3, 6, 9, 12 kg) as well as with various compression ratios (such as CR14, CR15, CR16, CR17 CR18).The harmful pollutants such as hydrocarbon (HC), carbon dioxide (CO2), carbon monoxide (CO) and nitrous oxides (NOx) of all samples were studied and reported here.
