INTAKE AIR CONTROL APPARATUS OF ENGINE

摘要

An intake air control apparatus of an engine includes a housing having an intake air inflow passage for receiving external air, an exhaust gas inflow passage for receiving recirculated exhaust gas, and an intake air supply passage for supplying the external air from the intake air inflow passage or the exhaust gas from the exhaust gas inflow passage to the engine. A motor gear rotates together with an output shaft of the motor. A connection gear is engaged and rotates together with the motor gear. A recirculation gear is engaged and rotates together with the connection gear. A recirculation valve opens and closes the exhaust gas inflow passage since the recirculation valve rotates together with the recirculation gear. An intake air gear is engaged and rotates together with the connection gear. An intake air throttle valve opens and closes the intake air inflow passage.

1. An intake air control apparatus of an engine, comprising:
a housing including an intake air inflow passage for receiving external air, an exhaust gas inflow passage for receiving recirculated exhaust gas, and an intake air supply passage for supplying the external air from the intake air inflow passage or the recirculated exhaust gas from the exhaust gas inflow passage to the engine; a motor which is a driving force source; a controller configured to control the motor; a motor gear rotating together with an output shaft of the motor; a connection gear engaged and rotating together with the motor gear; a recirculation gear engaged and rotating together with the connection gear; a recirculation valve disposed inside the exhaust gas inflow passage to open and close the exhaust gas inflow passage by rotating together with the recirculation gear; an intake air gear engaged and rotating together with the connection gear; and an intake air throttle valve disposed inside the intake air inflow passage to open and close the intake air inflow passage by rotating together with the intake air gear.
