摘要： The control system includes a motor controller (155) for controlling rotation of the motor (105) and a Host system (114) for carrying out a general control of a throttle system. A gear train (103) transmits the torque produced by the motor. A magnetic coupling (110) is provided for connecting and separating the transmission of the torque. The motor and the throttle valve are arranged in a U-shaped formation for a connection together one below the other, across the gear train. The coupling is arranged on the same side as the motor, in order to be axially aligned with it.

摘要： The throttle flap (1) is rotated about its axis (3) by a motor (6) with an electromagnetic clutch (9) jointly operated by a control unit (4) in response to a set-point input (5) and signals (25,26) from position sensors (16,17) of the flap and accelerator pedal (14) respectively. The flap sensor has a different output voltage characteristic for a range of positions covering normal idling speed and fast idling, where resolution is enhanced by a steeper characteristic gradient than that associated with higher speeds.

ADVANTAGE - Simple structure affords sufficient control of throttle valve in partially-open range.

摘要： A throttle valve control device for an internal combustion engine characterized in that a throttle valve is rotatably mounted on a throttle body via throttle shaft, that the configuration of a bore in the inner surface of the throttle body is a straight bore type in which the centre of rotation of the throttle valve is located on the centre line of the throttle body, that a spherically surfaced internal profile portion is provided in an idle control area which is in the vicinity of the fully closed angle of the throttle valve, that a spherically surfaced internal profile portion is further provided as an area continuing from the sphrically surfaced internal profile, that provided as an area continuing from the spherically surfaced internal profile is an area comprising a compound surface profile comprising in turn a spherical surface and a cylindrical surface substantially parallel to a flow of air or an area comprising a conical surface profile, and that the centre of the spherically surfaced profiles is on the centre line of the bore and vertically offset, whereby a gap between the spherical surface profile and the throttle valve increases as the opening of the throttle valve increases. When applied to an electronically controlled throttle valve control device, the device is designed such that an engine rotational speed changes 20 rpm for each incremental throttle valve opening of 0.10 in a low throttle valve opening area, thereby eliminating an idle control by an ISC valve.
