ABSTRACT:
A starting apparatus for an engine has a plurality of cylinders and an output shaft. The apparatus includes a power supply, an inverter having a switching element, a motor generator, an ECU, A crank angle sensor. The motor generator is coupled to the output shaft and connected to the power supply through the inverter. The ECU energizes the motor generator by controlling the inverter when the engine is started. The ECU causes ignition to occur in a specific cylinder that contains air-fuel mixture and is in an expansion stroke in an engine stopping state. The crank angle sensor indirectly detects a rotational speed of the motor generator. After the ignition caused, the ECU prohibits the motor generator from being energized until the rotational speed detected reaches or exceeds a predetermined value. As a result, the apparatus curbs an excessive increase in the temperature of a switching element.
