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.

Intake air control apparatus of engine

An intake air control apparatus of an engine includes an Intake manifold configured to guide intake air into a plurality of engine cylinders. A plurality of first intake air passages communicate with the cylinders. A plurality of second intake air passages are disposed in parallel with the first intake air passages and communicate with the cylinders. An Intake throttle shaft passes through the first intake air passages. An intake air throttle valve is disposed inside the first intake air passages, rotates with the Intake throttle shaft, and opens/closes the first intake air passage. A swirl throttle shaft passes though the second intake air passages. A swirl throttle valve is disposed inside the second intake air passages, rotates together with the swirl throttle shaft, and opens/closes the second intake air passages. An actuator rotates selectively the Intake throttle shaft and the swirl throttle shaft. A controller controls the actuator.

A supercharging engine supplying compressed air to a combustion chamber as intake air may include at least two cylinders, a deactivation cylinder being at least one of the cylinders, and selectively deactivated, a compressed air tank adapted to store compressed air supplied from a combustion chamber of the deactivation cylinder, a compressed air storage passage formed to communicate the compressed air tank with the combustion chamber of the deactivation cylinder, an intake manifold selectively communicating with the compressed air tank, and a compressed air valve selectively opening/closing the compressed air storage passage, in which compressed air may be transmitted from the combustion chamber of the deactivation cylinder to the compressed air tank as the compressed air valve is opened in a compression stroke during deactivation of the deactivation cylinder.
