    摘要: A vehicle supercharging system and a control method thereof are disclosed. The vehicle supercharging system includes: an engine generating power according to combustion of a fuel; a transmission including at least one friction clutch; an electric supercharger that compresses air by rotational force of a motor; an engine-side supercharging path part branching from an air supplying line that supplies air to the engine, passing through the electric supercharger, and joining the air supplying line; a transmission-side supercharging path part that sucks air separately from the engine-side air supplying line, passes through the electric supercharger, and supplies compressed air to the transmission; and a controller that operates the electric supercharger according to a driving state of a vehicle and that controls the engine-side supercharging path part for boosting the engine and the transmission-side supercharging path part for cooling or warming the transmission through control of valves.

    摘要: A multiple variable valve lift apparatus may include a moving cam formed of a hollow cylindrical shape, configured to be moveable in an axial direction of a camshaft while being rotated with the camshaft, and forming a plurality of cams implementing a cam guide protrusion device and different valve lifts from each other; an operation device selectively guiding a cam guide protrusion device to move the moving cam in the axial direction of the camshaft; a controller configured for controlling an operation of the operation device; a valve opening/closing device in contact with any one cam among the plurality of cams; a plurality of stopper grooves formed at an external circumference of the camshaft; and a stopper device provided at the moving cam and inserted to the stopper groove to be rotated at a position after the moving cam is moved.
