ANALYSIS OF PERFORMANCE AND EMISSIONS OF A V.C.R C. I. ENGINE USING METHYL ESTERS OF RICE BRAN OIL AS BIODIESEL

Biodiesel is one of the most promising alternative fuels for diesel engines. Biodiesel is renewable, non-toxic biodegradable, clean burning, high lubricity, biodegradable, low environmental impact, derived from vegetable oils and potential as a green alternative fuel to diesel engines and could be used directly in diesel engines without requiring extensive engine modifications. In this research work the performance and emissions of a single cylinder,4-stroke, variable compression ratio direct injection diesel engine with diesel, different blends of rice bran oil were measured by varying the load at different variable compression ratio (VCR-18, VCR-16 & VCR-14) and at different injection pressures (220 bar, 200 bar & 180 bar). The results proved that the use of biodiesel (produced from rice bran oil) in compression ignition engine is a viable alternative to diesel
