ゼルエンジンの始動装置。 In a diesel engine starting device in which an intake passage and an exhaust passage are connected via an exhaust recirculation passage, and a recirculation control valve that opens during cranking is interposed in the exhaust recirculation passage, the opening timing of the exhaust valve is set during cranking. A starting device for a diesel engine, characterized in that it has an exhaust valve control means that controls the exhaust valve to be faster than during normal operation.
