Estimating the term…
An internal combustion engine and control method therefor in which the engine is selectively started by combustion without cranking. The temperature in the combustion chamber of an engine cylinder is stabilized upon starting of the engine, thereby allowing secured staring without cranking. When predetermined idling stop conditions (or engine stop conditions) are established, the temperature in the combustion chamber is estimated based on engine operating conditions read before such establishment, and the period of maintaining a engine rotational speed in a predetermined low range before stopping the engine is calculated or estimated based on the estimated temperature in the combustion chamber. The engine is then stopped after the calculated or estimated period of maintaining the engine rotational speed in the predetermined low range.
An internal combustion engine that selectively starts an engine rotation thereof by combustion upon ignition, comprising:
An internal combustion engine comprising:
A control method for an internal combustion engine selectively started by combustion in an engine cylinder, wherein a pre-stopping operation is carried out in order to maintain engine rotational speed in a low range prior to a stopping of the engine.
