Abstract
A stop control system for an internal combustion engine, which is capable of accurately stopping a piston at a predetermined position during stoppage of the engine while preventing occurrence of untoward noise and vibration. After stopping the engine, the stop control systemfor the engineaccording to the present invention executes a first stage control (step) in which a throttle valveis controlled to a first stage control target opening degree ICMDOFPRE smaller than a second predetermined opening degree ICMDOF, in order to stop the piston at the predetermined position, before executing a second stage control (step) in which the throttle valveis controlled to the second predetermined opening degree ICMDOF. Further, the stop control systemstabilizes initial conditions at the start of the second stage control by setting a first stage control start rotational speed NEICOFPRE and a first stage control target opening degree ICMDOFPRE according to a change in a corrected target stop control start rotational speed NEICOFREFN (stepsand).
