- Abstract
Biodiesel is an oxygenated, sulphur-free, non-toxic, biodegradable and renewable alternative diesel fuel. It is known that CO, HC and smoke emissions of biodiesel are lower than those of diesel fuel. It is used without any significant setting and modification in diesel engines. Fuel injection timing is one of the significant parameters affecting the performance and emissions in diesel engines. By optimising fuel injection parameters, improvement in fuel economy as well as reduction in harmful exhaust emissions can be effected. In this study, the effects of fuel injection advance on engine performance and exhaust emissions were investigated experimentally in a four-stroke single cylinder direct injection diesel engine fuelled with biodiesel. Engine torque, brake power, specific fuel consumption, exhaust gas temperatures, CO, HC and NOx emissions were measured for injection timings of 24.9, 26.6 and 28.5ºCA at full load. By increasing injection timing to 26.6ºCA when running on biodiesel, engine torque and brake power increased by about 6%, and 8% improvement in specific fuel consumption were observed. In addition, it was also determined that CO and HC emissions decreased while NOx emissions increased by between 4-11%.
