Combustion phenomenon in diesel engine is mainly governed by characteristics of fuel injection and fuel spray system affected by its dimensions and operating condition. Fuel supply system is consisted of fuel injection pump, high pressure pipe and injection nozzle. In order to develope the more economical diesel fuel injection system, it is in need to carryout the fairly wide range experiments, which is quite impossible. Therefore, theoretical analysis for the numberous parameters is powerful method in this case. In the present study, equations of continuity of fuel oil in fuel injection system are solved to obtain the flow and pressure variation in diesel fuel system affected by injection pump speed, plunger diameter, pipe length and nozzle opening pressure.
