PURPOSE: A apparatus for mixing the EGR(Exhaust Gas Recirculation) gas of an engine with intake gas is provided to reduce the generation rate of harmful exhaust gas, and to increase output of the engine by variably controlling the supply amount of the EGR gas. CONSTITUTION: A apparatus for mixing the EGR gas of an engine with intake gas is provided to an intake pipe(7), an exhaust manifold, a main EGR pipe(10), a movable EGR pipe, and an actuator(12). The intake pipe supplies air to a cylinder of the engine through an intake manifold. The exhaust manifold discharges the EGR gas from the cylinder of the engine to outside. The main EGR pipe supplies some EGR gas of the exhaust manifold to the intake manifold. One end of the main EGR pipe is connected to the exhaust manifold, and the other end is connected to the intake pipe. The movable EGR pipe moves forward to a center of the intake pipe inside, or moves backward along the EGR pipe. The actuator moves the movable EGR pipe back and forth by a control of an ECU(Engine Control Unit). |
