る、電子タイマ。 The engine side and the pump side are connected via a cam mechanism, and the cam mechanism is driven by a flyweight biased by a spring and a hydraulic piston whose supply oil pressure is electronically controlled to adjust the fuel injection timing. In the electronic timer, the cam mechanism is set to advance the fuel injection timing to a maximum when the engine is stopped and gradually retard as the engine speed increases, and the hydraulic cylinder advances the cam mechanism. An electronic timer characterized in that it is set to be driven to retard fuel injection timing.
