Stop control apparatus for internal combustion engine

A stop control apparatus for an internal combustion engine, which controls a stop position of a piston in the engine upon stoppage of the engine. The engine is a 3-cylinder engine, a 5-cylinder engine, or an engine which can be operated in an operation mode in which a crank angle corresponding to a substantially central position of a crank angular range where the explosion stroke of a first cylinder and the compression stroke of a second cylinder overlap with each other, is in an overlap range where opening periods of the intake and exhaust valves of a third cylinder overlap with each other. The engine includes an intake air control valve provided upstream of the intake valve of each cylinder, for controlling an intake air amount of the engine. The intake air control valve is closed after a stop instruction of the engine, and opened after a closing timing of an intake valve of a last compression stroke cylinder which is in the compression stroke upon the engine stoppage.
