  • Patent number: 8944021
    Abstract: The invention pertains to a device for starting an internal combustion engine for handheld equipment such as chain saws, lawn mowers, lawn trimmers and the like, or for vehicles such as mopeds, boats or miniature aircraft. The starting device features an output element into which a starter torque can be introduced when the starting device is actuated. The output element is functionally connected to a crankshaft of the internal combustion engine in order to introduce a crankshaft torque therein. The functional connection between the output element and the crankshaft introduces variable crankshaft torque into the crankshaft depending on the rotational angle of the crankshaft at a constant starter torque. This advantageously improves force or torque characteristics for largely operating the starter device independently of the compression phase and the expansion phase of the internal combustion engine.

  • Patent number: 8731791
    Abstract: When an internal combustion engine is cranked up from a stopped position of a piston in a restart-time first ignition cylinder which is scheduled to start a combustion at the time of an automatic restart of the engine under an automatic stop of the engine during an idling-stop control, a restart-time ignition time interval between a time point when the cranking of the engine is started and a time point when the restart-time first ignition cylinder is initially ignited is calculated. A drive-start timing of a starter motor is delayed according to this restart-time ignition time interval. Thereby, the cranking of the engine is carried out by the starter motor under a state where the hydraulic pressure supplied from the electric oil pump has increased. Thus, the slip in the clutch of the CVT can be suppressed when the gas mixture in the restart-time first ignition cylinder is initially ignited.

  • Patent number: 7859150
    Abstract: A starter which may employed in starting an engine is provided. The starter includes an electromagnetic actuator and a pinion carrier. The pinion carrier includes a pinion and a holder. The holder retains a shift lever and transmits movement of the shift lever, as achieved by a magnetic attraction produced by the electromagnetic actuator, to the pinion, thereby shifting the pinion into engagement with a ring gear joined to, for example, an engine. The holder is made of material smaller in specific gravity than the pinion. Specifically, the holder is lower in mass or weight than the pinion, thereby permitting the magnetic attraction required to shift the pinion carrier through the shift lever to be decreased. This permits the electromagnetic actuator to be decreased in size.
