Abstract


This study investigates the performance  and  emission  characteristics of a variable compression ratio diesel engine which is fuelled with  sardine oil ethyl ester. A single cylinder four stroke diesel engine was used for the experiments at various load and speed of 1500 rpm. In order to find out optimum compression ratio experiments were carried out on a single cylinder four stroke variable compression ratio diesel engine. Tests were carried out at compression ratios of 16.0, 17.5 and 19.0. Results showed a significant improved performance and emission characteristics at a compression ratio 16.0. It has been observed that there is an increase in Break thermal efficiency, Exhaust gas temperature and Carbon monoxide for compression ratio 16, Hydro carbon and Nitric oxide is lower for compression ratio 16.
