摘要:
The present invention relates to a governor device for an internal combustion engine where a portion of the engine output is taken off as driving force for vehicle mounted accessory equipment which requires constant speed rotation with changes in load. By controlling the intake air quantity passing through a bypass passage which bypasses a mixing device for mixing fuel and intake air at a predetermined ratio, controlling a sub-throttle valve provided in an intake passage in series with a main throttle valve, and controlling a supply quantity of auxiliary gas fuel so that a detected air-fuel ratio is constant, the engine output is increase/decrease controlled in spite of changes in load in accessory equipment, to give constant engine rotational speed and good operability of an auxiliary power take-off device.

The invention relates to a sensor provided with a magnet (52) and a magnetic detecting element (53) comprising a detection shaft (38a), a detection disc (59a) which is fixed to the detection shaft, a magnetic piece (59b) which is fixed to the outer circumference edge of the detection disc, a yoke (59c) which is disposed to hold the magnetic piece in a predetermined shaped gap, and the magnet and the magnetic detecting element both fixed to the yoke. The sensor is used for a drive force auxiliary device which combines a human power drive force and a motor drive force. The drive force auxiliary device comprises a torque sensor (30), a vehicle speed detecting means (40) for detecting a running speed of the drive force auxiliary device, and an auxiliary power means using a motor (M). The vehicle speed detecting means (40) detects a running speed by virtue of the drive force auxiliary device based on a rotation position signal obtained from a rotor rotation position detector. The torque sensor (30) includes a mechanism for automatically making a zero point adjustment by compensating an output voltage.
