STOP CONTROL DEVICE AND METHOD FOR INTERNAL COMBUSTION ENGINE

A stop control device for an internal combustion engine, capable of accurately stopping the piston at a predetermined position while compensating a variation in and changes over time in stop characteristics of the piston. When the rotational speed (NE) of an engine (3) becomes less than a stop control start rotational speed (NEIGOFTH) after the engine (3) is stopped, a stop control device (1) for the engine (3) controls a throttle valve (13a) to open the throttle valve (13a) (Step 42). This controls a final compression stroke rotational speed (NEPRSFTGT) to a predetermined reference value (NENPFLMTO) to thereby control the stop position of a piston (3d) to a predetermined position. Also, the stop control device determines the correlation between the stop control start rotational speed (NEIGOFTH) and the final compression stroke rotational speed (NEPRSFTGT) (Step 5, FIG. 9 ), calculates and learns a target stop control start rotational speed (NEICOFREFX) on the basis of the determined correlation (Step 11), and uses the result of the calculation and leaning in order to perform the above-mentioned stop control.
