A starter assembly which includes a switch for energizing a solenoid. Energizing the solenoid biases a starter gear into engagement and energizes the starter motor. A thermally responsive switch is positioned to absorb heat generated by operation of the electric motor and is disposed in an electrical line controlling operation of the switch controlling the solenoid wherein opening of the thermally responsive switch results in the opening of the solenoid switch. The use of such a thermally responsive switch de-energizes the electric motor when the electric motor is subjected to elevated operating temperatures that might otherwise cause damage to the electric motor. The starter assembly may also include control circuitry that includes a microprocessor wherein the control circuitry is operably coupled with the switch controlling the solenoid. The control circuitry is programmed to de-energize the solenoid upon the satisfaction of predetermined conditions to thereby prevent damage to the electrical motor.

An electric starter system (100) for a motorcycle with a mechanical kick-start device (200) and a transmission main shaft (340) which rotates in a starting and drive rotational direction (x) and the kick-start device (200) has a kick-start pinion configured for axial coupling to a kick-start clutch part (240) which is connected to the transmission main shaft (340) in a torque-transmitting manner. The electric starter system (100) comprises an electric starter motor (110) with a starter shaft pinion (112) that can be driven thereby, which makes it possible to carry out the installation or retrofitting thereof with fewer modifications of the original components, less expenditure of time, and/or easier, and/or faster. This is achieved because a torque of the electric starter motor (110) can be transmitted from the starter shaft pinion (112), preferably at the end face, to the kick-start clutch part (240), in particular via interposed starter gearing (120).

In a vehicle control device with an automatic engine stop function, when the engine is in a non-operating state and the shift lever is operated to the parking range, the engine is controlled to start to supply operating oil to a valve timing changing means. The valve timing changing means is thereupon caused to change the intake valve close timing (IVC) to a predetermined advance angle position and subsequently locked thereat. The engine is then controlled to stop.

An engine accessory drive (EAD) system for an engine includes a motor-generator (MGU) unit operably coupled to an accessory. The EAD system also includes a gearbox assembly, which includes a first gear train operably coupled to the MGU, and a second gear train operably coupled to an output of the engine. The gearbox assembly also includes a clutch selectively coupling the first gear train with a second gear train. The EAD system further includes a starter assembly, which includes a starter shaft operably coupled to the second gear train. The starter assembly also includes a starter pinion coupled to the starter shaft, and an actuator configured to selectively engage the starter pinion with a flywheel of the engine. Further yet, the EAD system includes an EAD controller configured to selectively operate the EAD system in one of a generator mode, an accessory drive mode, and a starter mode.

An apparatus for starting an engine, including a motor, an output shaft driven by the motor, a pinion provided along the output shaft, and an electro-magnetic solenoid device. The electro-magnetic solenoid device is configured to push the pinion axially toward a ring gear of the engine to mesh the pinion with the ring gear and transfer a rotational force, which is referred to as a motor torque, generated by energization of the motor from the pinion to the ring gear, thereby starting the engine. The apparatus is configured such that, at starting of the engine in its warmed-up state, the motor torque can continue to be applied from the pinion to the ring gear until at least the second compression stroke even when an engine speed varies.
