ENGINE STARTING APPARATUS

摘要

An apparatus for starting an engine, including an inertia-engagement-type starter. In the apparatus, a starter-characteristic switching mechanism is configured to switch an output characteristic of the starter between a plurality of output characteristics including at least a low-torque high-speed characteristic and a high-torque low-speed characteristic, where the output characteristic of the starter is hereinafter referred to a starter characteristic. A timing controller is configured to control when the starter-characteristic switching mechanism switches the starter characteristic such that the starter characteristic is set to the high-torque low-speed characteristic from initiation of actuation of the starter at least until a pinion successfully meshes with a ring gear, and after the pinion has successfully meshed with the ring gear, the starter characteristic is switched from the high-torque low-speed characteristic to the low-torque high-speed characteristic at which the engine is cranked by the starter.

1. An apparatus for starting an engine, comprising:
an inertia-engagement-type starter configured to utilize an attractive force of a solenoid to push a pinion into an engaged position with a ring gear of the engine and then transfer a rotational force of the motor from the pinion to the ring gear to start the engine; a starter-characteristic switching mechanism configured to switch an output characteristic of the starter between a plurality of output characteristics including at least a low-torque high-speed characteristic and a high-torque low-speed characteristic, the output characteristic of the starter being referred to a starter characteristic; and a timing controller configured to control when the starter-characteristic switching mechanism switches the starter characteristic such that the starter characteristic is set to the high-torque low-speed characteristic from initiation of actuation of the starter at least until the pinion successfully meshes with the ring gear, and after the pinion has successfully meshed with the ring gear, the starter characteristic is switched from the high-torque low-speed characteristic to the low-torque high-speed characteristic at which the engine is cranked by the starter.
