A stop control system includes a direct-injection type internal combustion engine, a fuel injection valve, an accessory configured to be driven by the internal combustion engine, and a controller configured to operate the internal combustion engine. The controller is configured to control the accessory during a period from start of fuel cut to a moment immediately after the internal combustion engine stops, such that when the internal combustion engine stops completely, the output shaft comes, in a rotational direction, to a target stop position where an intake port is closed.

Stop control system for direct-injection type internal combustion engine

A vehicle includes a generator, an internal combustion engine for driving the generator, a catalytic device, and a controller for controlling the operation of the internal combustion engine. At a start of the internal combustion engine to allow the generator to start generating electricity, the controller, until the catalytic device reaches an activated state, operates the internal combustion engine in a warm-up mode such that the driving force of the internal combustion engine for driving the generator is below a value at which electricity is generated, and the controller, after the catalytic device reaches the activated state, operates the internal combustion engine in an electricity generating operating mode such that the driving force of the internal combustion engine is enhanced to the value at which electricity is generated to allow the generator to generate a predetermined quantity of electricity.
