Claims

[Scope of Claim for Utility Model Registration] (1) The discharge side of the oil pump is communicated with the electronic timer for fuel injection timing control through a timer solenoid valve that controls the advance angle of the electronic timer, and is based on the engine operating state. In an engine having an automatic timer device for a fuel injection pump in which the timer solenoid valve is drive-controlled, a switching valve is provided between the oil pump and the timer solenoid valve, and the timer solenoid valve is bypassed from the switching valve. a switching valve that forms a bypass passage that can communicate with the electronic timer, and switches the switching valve so that the discharge side of the oil pump is communicated with the electronic timer via the bypass passage when an engine starting state is detected; An engine starting device characterized by being provided with a control means. (2) The discharge side of the oil pump is communicated with the electronic timer via a timer solenoid valve that controls the advance angle of an electronic timer for fuel injection timing control, and the timer solenoid valve is driven based on the engine operating state. In an engine that has an automatic timer device for the fuel injection pump to be controlled and also has a spark plug for igniting the injected fuel, a switching valve is provided between the oil pump and the timer solenoid valve, and the timer solenoid valve is connected to the switching valve. forming a bypass passage capable of communicating with the electronic timer by bypassing the engine, and controlling the switching valve so that the discharge side of the oil pump is communicated with the electronic timer via the bypass passage when an engine starting state is detected. An engine starting device comprising a switching valve control means and an ignition control means for advancing the ignition timing of the ignition plug when an engine starting state is detected.
