Abstract
A device for controlling the flow of intake air to an engine includes an air flow meter for detecting the flow rate of air, an electronically controlled throttle for opening and closing a throttle valve, and an electric motor that drives the throttle valve via a gear. The air flow meter and electric motor are arranged on opposite respective sides of a plane that include an axis of the throttle valve and that extends in a direction of the flow of intake air in the engine.
Claims3
A device for controlling the flow of intake air to an engine, comprising:
- an electronically controlled throttle, including a throttle valve, provided in a suction pipe for introducing air into the engine;
- an air flow meter to detect the air flow which flows in the suction pipe;
- an electron motor to drive the throttle valve;
- and
- a mechanism, including a gear, which transfers driving force of the motor to the throttle valve;
- wherein said air flow meter and said electric motor are arranged on opposite respective sides of a plane that includes an axis of the throttle valve and that extends in a direction of the flow of intake air in the engine.
