PROBLEM TO BE SOLVED: To rapidly start an internal combustion engine by accurately estimating the stop position of the internal combustion engine and injecting a fuel in a cylinder for which an ignition timing comes first at the time of starting beforehand. SOLUTION: A TDC exceeding rotating speed Ntdc which is the rotating speed of the engine when any of the cylinders of the engine exceeds a top dead center is detected, the stop crank angle CAs of the engine is estimated by a map in which a relation between the TDC exceeding rotational speed Ntdc and the stop position of the engine is obtained by experiments beforehand, and a cylinder stopping in such a range that involves a part of a compression stroke in stopping is set (S110 to S130). Then, lean injection is performed at the fuel injection timing of the cylinder (S170), and a fuel is injected by a correction amount when the cylinder does not exceed a top dead center in a compression stroke by the estimation thereafter (S240). On the other hand, when it exceeds the top dead center in the compression stroke by the estimation thereafter, the fuel is ignited and burned in the compression stroke and the fuel is injected into the next cylinder (S270).
