Abstract
A stop control apparatus (100) for an internal combustion engine performs stop control of a three-or-less cylinder internal combustion engine (200). The stop control apparatus for the internal combustion engine is provided with: a determining device (161) configured to determine a compression stroke immediately before the internal combustion engine stops; and a throttle valve controlling device (168) configured to control an opening degree of a throttle valve (208) to be a predetermined opening degree while an intake valve (211) is closed in all cylinders, in the compression stroke immediately before the internal combustion engine stops, which is determined by the determining device. This reduces an influence of an intake negative pressure in an intake stroke, and makes it possible to preferably control the crank angle when the engine stops, even in the three-or-less cylinder internal combustion engine.
