Summary: | A starting device for an internal combustion engine is capable of increasing starting torque as well as supplying air to a cylinder that is on the expansion stroke without separately providing a means for supplying high-pressure air. Communication control valves control the states of communication between cylinders of the engine. A crank angle detector detects the crank angle of a crankshaft of the engine. A compression/expansion identification part identifies the compression stroke or the expansion stroke of each cylinder. Fuel is injected into a cylinder on the expansion stroke and ignited therein, and the expansion stroke cylinder is placed in communication with a cylinder on the exhaust stroke by a communication state control part for a prescribed time after the ignition thereof, after which the expansion stroke cylinder is further placed in communication with a cylinder on the compression stroke for a prescribed time. |
