A stating device for an internal combustion engine predicts whether a starter is required to assist a crank of the engine before igniting fuel in a cylinder in an expansion stroke, and starts the starter before igniting the fuel in a cylinder in an expansion stroke if it is decided that the starter is required.
Claims20
A starting device for an internal combustion engine that ignites fuel in an expansion-stroke-cylinder that is a cylinder in an expansion stroke from among a plurality of cylinders of the internal combustion engine to start the internal combustion engine, comprising:
- a predicting unit that predicts a state of a crank of the cylinders if the fuel in the expansion-stroke-cylinder is ignited;
- and
- a determining unit that determines whether to start a starter to assist movement of the crank based on the state predicted.
