THROTTLE VALVE CONTROL SYSTEM FOR AUTOMOTIVE ENGINE |
摘要 |
A throttle valve control system calculates a throttle opening of a throttle valve according to a predetermined relationship based on the displacement of an accelerator and regulates an air-fuel ratio at which a fuel mixture is applied to the cylinders. The speed at which the throttle valve is driven is controlled, based on the throttle opening and the air-fuel ratio, so as to be lower when the air-fuel ratio provides a lean fuel mixture than when the air-fuel ratio provides a rich fuel mixture. The throttle valve is finally driven to open to the throttle opening at this speed.
