ABSTRACT:
An electronic throttle apparatus permits aggregating of various parts and rationalization of installation, and can simplify assembling operation and wiring operation to an engine room for rationalization of an installation space. The throttle apparatus for an engine includes a throttle body housing therein a throttle valve and disposed in an air intake of the engine, a throttle actuating motor, a throttle position sensor detecting a throttle valve angle and an air flow sensor located on upstream of the throttle valve and measuring an intake air flow rate. The throttle actuating motor, the throttle position sensor and the air flow sensor are mounted on the throttle body.
