Emission and Performance Characteristics of VCR Engine with Pumpkin Seed Bio Diesel Blends

Abstract

The objective of the present study is to analyze the emission and performance characteristics at different compression ratio in VCR diesel engine using pumpkins seed. Bio diesel is prepared by trans-esterification process in biodiesel plant. Blends (20%, 40% and 60%)of pumpkin seed biodiesel and diesel blends are prepared and test were conducted at the load conditions (3-12 kg) The enforcement criterias like exhaust emissions, brake thermal efficiency( BTE) and Brake specific fuel consumption ( BSFC) been assessed and analyzed. And experimental results shows BSFC is same for diesel and biodiesel blends and at higher loads, 40% biodiesel blend has efficiency closer to the diesel, NOX emission in biodiesel blends have same at different loads, CO2 emissions gradually increases with increasing load.
