するディーゼル機関の燃料噴射時期調整用検出装置。In a single or multi-cylinder diesel engine, an arbitrary fuel injection pump detection body is provided, and a pressure detection chamber is formed in the detection body that communicates with the injection hole of the fuel injection pump. The movable body is moved back by a mechanism, and is pushed by the pressure of high-pressure fuel injected from the nozzle during injection, overcoming the return mechanism, and the pushing/returning performance of this movable body is improved. A pressure detection contact that is opened and closed by a pressure detection contact is provided, a vent hole that communicates the pressure detection chamber with outside air is provided in the detection body, and an on-off valve that opens when the pressure detection contact detects fuel injection is provided in the vent hole. A detection device for adjusting fuel injection timing for a diesel engine, characterized in that fuel injection is detected by opening and closing a pressure detection contact, and residual pressure in a pressure detection chamber is eliminated by an opening and closing valve.
