Abstract: Day by day increase in price of fuel especially in India have created the necessity to develop an alternative fuel having the same characteristics as fossil fuel diesel or petrol have. Simultaneously, rapid decreasing of fossil fuel reserves all over the world has become a major problem for all engineers as almost all industries use petroleum products for producing power. Biodiesel or methyl ester extracted from microalgae is experimented for its combustion and emission characteristics. The same is matched with the corresponding characteristics of fossil fuel diesel. Considerable deviations are found. In order to improve the characteristics of biodiesel, the piston is coated with zirconia and the parameters obtained using VCR engine is compared with the parameters obtained by using exhaust gas recirculation along with thermal barrier coating on piston crown. Considerable reduction in emission of oxides of nitrogen is found.
