Effect Of Different Injection Strategies On Engine Performance Of A Diesel Engine Operating With Biodiesel: A Modeling Approach

Clean and high performance energy production was become the priority for the researchers. Various injection strategies have been used to effectively reduce exhaust emission from diesel engine. The purpose of this study is to investigate the effect of different start of injection on engine performance and exhaust emission of a single cylinder diesel engine. The commercial one-dimensional simulation software is used to simulate the behavior of the engine when it is operated with diesel fuel and biodiesel blend.  The result among others include engine brake torque, brake power, mass fraction burn, rate of heat release and exhaust emissions are include carbon monoxide, carbon dioxide. The simulation result revealed that the early start of fuel injection resulted to increase peak pressure and therefore increase the emissions of nitrogen oxide due to high temperature combustion in engine cylinder. Engine brake torque and brake power slightly reduced. However, the brakes specific fuel consumption increases significantly when the early injection strategy is used.
