DIESEL ENGINE WITH MULTI FUEL INJECTION SYSTEM

摘要

A diesel engine with a multi fuel injection system is provided to improve performance of the engine by using at least two fuel cams and fuel pumps for each cylinder, and to simplify the structure by eliminating the need of an additional reversing device. In a diesel engine injecting fuel through a fuel injector(170) provided in a combustion chamber of each cylinder, the diesel engine with a multi fuel injection system includes a cam shaft(100) extended toward one side of an engine crank shaft, two fuel cams(110) provided at the cam shaft at different angles and rotated by the cam shaft and driving fuel pumps provided in the each cylinder respectively, fuel pumps(130) moving with each cam and driven at different time intervals according to bending of the fuel cam, two fuel injectors injecting fuel supplied from the each fuel pump at a predetermined time interval, and a non-return valve provided at a fuel port of the fuel injector for preventing backflow of the fuel, where outlets of the non-return valve are integrally connected to each other through one pipe body and connected to each fuel injector in common.
