Study of Combustion and Vibration on DI -Diesel Engine Fueled With Rice Bran Methyl Ester Injection and Ethanol Carburetion

In this present paper experimental study results of combustion and vibration on DI -Diesel engine fueled with rice bran methyl ester injection and ethanol carburetion are presented. The Present research trend is to replace Petro-diesel by renewable alternative fuels in view of fast depletion of petroleum reserves and to reduce the exhaust emissions from engines. In this study biodiesel (Rice bran methyl ester) is used as a total replacement to Petro-diesel. It is proved that biodiesel reduces the engine emissions but for the Nitric Oxide emission which is emitted more than that when neat diesel fuel is implemented. This is the main reason to turn our attention to dual fuel operation with rice bran methyl ester injection and ethanol carburetion to reduce even Nitric Oxide emission (NO) also. Detail study of combustion performance, engine performance, exhaust emission and vibration analysis on DI -Diesel engine fueled with Rice Bran Methyl Ester Injection and Ethanol Carburetion is carried out. Betterment is observed at a particular ethanol mass flow rate. Experimental study results of combustion and vibration analysis part only discussed in this present paper.
