Abstract

For the last two decades the search for alternate fuels for diesel engines has been intensified to substitute fossil fuels. This is mainly due to the depletion of fossil fuels and environmental pollution. Among many different types of alternate fuels available, vegetable oils and their blends have come across the world as alternative fuels. In the present paper, experimental investigation for the performance and emissions of a direct injection diesel engine with Safflower oil and Safflower diesel blends at three injector opening pressures 200, 220, and 240 bar are carried and compared with standard data of diesel fuel. It has been observed that safflower oil blend B20 can be used successfully with three pressures in place of diesel fuel with lower exhaust emissions and better performance.
