摘要： An electronic throttle valve control system prevents rapid rotation of a throttle valve reliably when the control system has a failure. A throttle valve controls the amount of intake air to an internal combustion engine, an electric motor drives the throttle valve, and a rotational speed reduction mechanism reduces the rotation of the electric motor to control the rotation of the throttle valve. An urging mechanism urges the throttle valve in the closing direction. An attenuation mechanism attenuates the speed at which the throttle valve is rotated in the closing direction by the urging mechanism when the control system has a failure. The attenuation mechanism is the electric motor in a regenerative mode or an air damper.

摘要： An electronic throttle valve control system prevents rapid rotation of a throttle valve when the control system has a failure. A throttle valve controls the amount of intake air to an internal combustion engine, an electric motor drives the throttle valve, and a control section controls the electric motor. The throttle valve has an urging mechanism for urging the throttle valve in the closing direction. The control section shifts the electric motor to a regenerative mode when the control system has a failure to control the speed at which the throttle valve is rotated in the closing direction by the urging force of the urging mechanism. The throttle valve is therefore rotated slowly in the closing direction by the urging force of the urging mechanism and then held in a predetermined opening position.

摘要： A throttle body includes a housing that accommodates a connector for a rotation shaft of a throttle valve disposed in the throttle body and a throttle position sensor, a fuel return passage that communicates the housing with an air intake passage in the throttle body, a T-shaped pipe that communicates with the air intake passage upstream from the throttle body to function as a pressure control chamber, and an air inflow passage that communicates the housing with the T-shaped pipe. The throttle body smoothly returns the fuel accumulated in a housing that accommodates a connector that connects a throttle position sensor to the end of the rotation shaft of a throttle valve to an air intake passage.
