ーゼルエンジン。 A timer including a pressure responsive actuator for controlling the timing of fuel injection, a valve device interposed between the pressure responsive actuator and a pressure fluid source, and directly driving the valve device in response to changes in atmospheric pressure. The engine is equipped with an atmospheric pressure sensing device such as a diaphragm or bellows, and when the engine is operated at high altitude, the atmospheric pressure sensing device drives a valve device, and the pressure-responsive actuator of the timer adjusts the fuel injection timing from when operating at low altitude. A diesel engine equipped with a high altitude compensation device, characterized in that it is configured to advance the engine angle.
