Abstract
The fuel injection pressure of a diesel engine fuel injection system depends on the high pressure pump and directly affects to spray structure, leading to changes in the process of combustion mixture formation and burning fuel, affects on power and emissions of engine. Determining direct injection pressure on operating fishing vessels is an impossible task. Therefore, determining reduction level of pressure in the high pressure pipes to timely repair and maintenance of fuel injection systems, especially high-pressure pumps, will help improve working efficiency and prevent incidents for main diesel engine. This paper presents a solution to design and manufacture the device to measure fuel pressure in the high pressure pipes connected to computer in order to diagnose the status of the maindiesel engines of fishing vessels.
Keywords: fuel injection pressure, diesel engine, high pressure pump, fuel injection system.
