Performance Characteristics of Diesel Engine Using Biodiesel and their Esters as Fuel

ABSTRACT: Biodiesel is one of the available alternative fuels in the market. It is derived from biomass, which is one of the sources of renewable energy. Coconut oil is one of the sources of biodiesel and of all the other sources, it would be best in tropical countries biodiesel done to help the readers become aware of this the performance, emission and combustion characteristics of diesel engine using mahua methyl esters. In the present work, mahua methyl esters and its blends with diesel were used as fuel. Various proportions of mahua methyl ester fuel blends (25 % and 50%) were used for conducting the performance tests at varying load conditions. Various parameters such as thermal efficiency, specific fuel consumption, emission of carbon dioxide, carbon monoxide, hydrocarbons and oxides of nitrogen gases in exhaust were recorded. The important properties of mahua methyl esters are compared with diesel standards. can be used in diesel engines without any engine modifications No new experiments have been conducted to prove any theory or hypothesis regarding the Biodiesel production is a very modern and technological area for researchers as an alternative fuel for diesel engines because of the increase in the petroleum price, its renew ability and the environmental advantages. Biodiesel can be produced from renewable sources such as vegetable oil, animal fat and used cooking oil. Currently, the cost of biodiesel is high as compared to conventional diesel oil because most of the biodiesel is produced from pure vegetable oil.
