To suppress vibration of an internal combustion engine at a time of stop of the internal combustion engine and to stabilize crank stop position based on piston position for improving startability of the internal combustion engine.
In a stop control method of the internal combustion engine 1 provided with a reciprocating piston 3 and a throttle 13 as an air quantity change means changing suction air quantity to a combustion chamber 5 and controlling piston stop position by changing suction air quantity, a condition such as rotation load of the internal combustion engine is estimated by a rotation load estimation means 34 after stop operation of the internal combustion engine 1 by a combustion completion control means 33, and suction air quantity is changed by the air quantity change means 35 according to the condition. The air quantity change means 35 reduces suction air quantity to predetermined quantity and then preferably increases suction air quantity to the predetermined quantity when rotation speed of the internal combustion engine reaches predetermined rotation speed.
