PERFORMANCE CHARACTERISTICS OF BIODIESEL MIXTURES IN A VARIABLE COMPRESSION RATIO ENGINE WITH CR 17

Petroleum based fuels are still the base of the automobile industry. The rapid depletion and fuel price points towards the need of alternative fuels. The biodiesel play a vital role as an alternative for diesel and the researchers are very much interested to investigate its performance from various sources. Performance and emission characteristics of biodiesel fuel from jatropha and rubber seed oil were studied experimentally. Bio-diesels are prepared from rubber seed oil and jatropha using transesterification process. A single cylinder, four stroke, constant speed, water cooled, direct injection variable compression ratio diesel engine is used for the experiment. The performance of the engine is measured using eddy current dynamometer and the emissions such as CO, CO2, HC and NOx is measured using exhaust gas analyzer.
