噴射装置のポンプ配置構造。 A fuel injection device for an internal combustion engine, comprising a main fuel needle that opens and closes an injection passage for a main fuel with a high ignition temperature, and an auxiliary fuel needle that opens and closes an injection passage for an auxiliary fuel that ignites the main fuel and has a low ignition temperature. In the pump arrangement structure, the auxiliary fuel pump pumps the auxiliary fuel to the auxiliary fuel injection passage along a rotatably supported drive shaft, and the auxiliary fuel pump applies back pressure to the main fuel needle to cause the main fuel injection passage to flow. A main fuel needle control pump that pumps control oil to open the exhaust valve, and an exhaust valve drive pump that drives oil that opens and closes the exhaust valve are arranged as one group, and each pump is fixed to the drive shaft. A pump arrangement structure for a fuel injection device for an internal combustion engine, characterized in that it is operated by a cam.
