Electronic controlled fuel injection system using the mechanical fuel pump and engine governor for the diesel engine

摘要

This invention relates to an electronically controlled fuel injection device using a mechanical fuel pump and the governor of the diesel engine as, its purpose is to provide an electronically controlled fuel injection device is configured for conventional mechanical fuel pump at a low cost by utilizing as is possible to operate by a cam is provided so as to correspond to each cylinder of the diesel engine. The present invention therefor is provided so as to correspond to each cylinder of a diesel engine, by a cam which rotates by receiving the power of the engine to move the plunger within the barrel is provided with upper and lower compressing the fuel, a plurality of mechanical fuel pump for sending ; Compression from the mechanical fuel pump, a common rail fuel is stored at a constant pressure to be sent; Are provided on the high pressure pipe extending to an injector for each cylinder from the discharge line or common rail of the common rail of a plurality of solenoid valves to regulate the fuel supplied to the injector; Mechanical fuel pump and the engine of a diesel engine having an; and an electronic injection control apparatus cooperating with the governor of the diesel engine to control the shape of the injection quantity and the injection timing and injection rate of the fuel injected from the injector to control the solenoid valves and what about the electronically controlled fuel injection device using the governor as its technical base.
