Abstract
PURPOSE:To improve controllability by installing two throttle valves arranged in parallel and a throttle valve arranged in series with said throttle valves and motor-driving one of the throttle valves arranged in parallel and the throttle valve arranged in series according to the stepping-in quantity of an accelerating pedal. CONSTITUTION:Two throttle valves 1 and 2 are arranged in parallel in the air flow passage in a throttle body. and a throttle valve 3 is arranged on the upstream in series with the valves 1 and 2. The throttle valve 1 is opened and closed through a cable 5 by an accelerating pedal 4, and the throttle valves 2 and 3 are interlocking-connected through a link 10 and operated by the drive of a single motor 6. Further, the throttle valve 1 is urged to the closing side by a return spring 11, and the throttle valve 2 is urged to the closing side by a spring 13, and the throttle valve 3 is urged to the opening side by a spring 12. The motor 6 is controlled by a controller 7 according to the engine operation state such as the stepping quantity of an accelerating pedal.
