DEVICE FOR STOPPING DIESEL ENGINE

A device for stopping a diesel engine, the device for a common rail diesel engine is provided which can control an engine phase when the engine is stopped so that the engine can be restarted quickly next time. The device includes an engine phase determining means 42 which determines an engine phase based on a crank angle and an angle of a camshaft, an engine stop position determining means 43 which stores a stopping time ST spent from the issuance of an engine stop request to the stop of the engine and obtains an engine phase when the engine is stopped based on the engine phase, resulting when the engine stop is requested, and the stopping time ST, and an at-time-of-stopping injector control means 44 which controls fuel which is injected from the fuel injectors 16 so that the engine phase obtained by the engine stop position determining means 43 when the engine is stopped after the engine stop request is made allows a piston in a specific cylinder to stop at a bottom dead center of a compression stroke.
