Nowadays, Diesel engines are so popular, especially in the field of transportation and marine. It has also improved over the generations, from a mechanical control system to an electronic control system. The Common-rail fuel system is considered the best development system on Diesel engines today. The injection pressure is very high, however, to increase power, reduce consumption and emission, further improvement is necessary. In this research, AVL - FIRE software was used to studying the effect of injectors to combustion chamber, the injection hole diameter related to: power, torque as well as exhaust gas on Diesel engine (Toyota Hiace 2KD-FTV).
The results show that with d=0.16mm, the best power, low fuel consumption but high emissions, with d=0.2mm, the lowest emission. The results of this research improve fuel injectors and Diesel engine performance.
