Reproducible vegetable oils have many advantages as alternative fuels in order to supplement diesel fuels. Compared with common diesel fuel, however, the use of vegetable oils results in higher exhaust emissions and carbon deposits because of the high viscosity and low volatility. The work presented here describes experiences with stable water emulsified rapeseed oils in a small direct injection diesel engine. The purpose of this paper is to demonstrate animprovement in engine performance and a reduction in exhaust emissions by changing the injection nozzle diameter and the valve opening pressure. The results show that BSFC, HC, CO, and Smoke emissions decrease simultaneously with a decrease in the injection nozzle diameter as compared with that of gas oil. In the present experiment, the optimum nozzle diameter is 0.22mm as regards engine performance and exhaust emissions.
