The Effects of Injection Timing on BDF in an IDI Diesel Engine

Abstract:

Biodiesel fuel (BDF) can be effectively used as an alternative fuel in diesel engines. The BD, however, may affect performance and exhaust emissions of the diesel engine because it's physical and chemical properties, such as viscosity, compressibility and so on, are different from the diesel fuel. To investigate effects of an injection timing on characteristics of performance and exhaust emissions with the BDF in an IDI (Indirect injection) diesel engine, this research applied the BDF derived from soybean oil in this study. The engine was operated with six different injection timings from TDC to BTDC 12°CA and six different loads at engine speeds of 1500 and 2000 rpm. In less then the BDF 20, the diesel engine showed the similar trend compare to the diesel fuel. But, the best injection timing with the BD 50 was 2°CA retarded compare to the diesel fuel.
