る発電用デイーゼル機関の保護装置。 The lubricating oil pump is driven by an external power source, and has an air control valve B that distributes starting air to each cylinder of the engine at a predetermined timing, and a starting air supply valve G that opens and closes an air passage to the air control valve. In a diesel power generation engine, a signal generator H generates a stop signal only when the external power source is lost and fuel supply to the engine is continuously stopped for a certain period of time and the engine main shaft is rotating during that time; An air pipe line b that bypasses the air supply valve G and is connected to the air passage between the air control valve B, and an opening/closing device that is provided in the air pipe line and opens and closes the pipe line according to a signal from the signal generator. A protection device for a diesel engine for power generation, comprising a valve C and an air control valve B that sends high pressure air to each cylinder during a compression stroke in accordance with the timing of opening of the opening/closing valve of the engine.
