EFFECT OF ADDITIVE AND RAW RUBBER SEED OIL MIXTURE IN A BIODIESEL

The main advantage favouring biofuels is that they are biodegradable and thus do not cause harm to the environment. Department of Energy study showed that the production and use of biodiesel, compared to petroleum diesel, resulted in a 78.5% reduction in carbon dioxide emissions The present study aims to investigate the importance of additives in biodiesel blends. Here DEE (Diethyl ether) used as the additives. The main aim of this study is to analyse the effect of compression ratio on the performance and emission of blends of biodiesel with and without using additives. The test has been conducted on three different fuels blends on a single cylinder VCR (Variable Compression Ratio Engine) DI diesel engine at a compression ratio of 16. The performance parameters include BTE, SFC, BP, Volumetric Efficiency and Mechanical efficiency. The exhaust gas emission is found to contain CO, HC, NOx and CO2.The three different fuel blends are 1) standard diesel 2) 20%Jatropha biodiesel, 3) diesel+20%Jatropha+5%DEE+ 3ml raw rubber seed oil. The result of the experimental works has been compared with standard diesel and it concludes considerable improvement in the performance parameters, as well as exhaust emissions.
