Nimesh G. Gandhi,  Hardik M. Patel
This study involves theoretical aspects of four Stroke four Cylinder Diesel Engine system. This study investigates the experimental performance of four Stroke four Cylinder Diesel Engine system. For this aim, an experimental system consisting of original components from four Stroke four Cylinder Diesel Engine systems, system has been set up and instrumented. The system is suggested to test under steady-state operating conditions. Four stroke Four cylinder diesel engine model has been analyzed experimentally. To optimize injection pressure of diesel engine from 100 bar to 250 bar with the increment of 50 bar by shim adjusting inside the atomizer for increasing engine performance values such as power, torque, and specific fuel consumption have been measured and minimize emission of engine using Taguchi method. According to results, by optimizing injection pressure, the maximum performance has been obtained at 150 bar. In addition, high injection pressure for O2 and CO2, low injection pressure for NOx and smoke level must be preferred for decreasing emissions.
