    Abstract: A continuous variable valve duration apparatus may include a camshaft, a cam unit on which a cam is formed, of which the camshaft is inserted thereto and of which a relative phase angle with respect to the camshaft is variable, an inner bracket transmitting rotation of the camshaft to the cam unit, a wheel housing in which the inner bracket is rotatably inserted, on which a guide groove parallel to the camshaft is formed, and on which a guide hole vertical to the camshaft is formed, a guide portion including a guide shaft inserted into the guide hole for guiding movement of the wheel housing and a control portion including a control shaft disposed parallel to the camshaft and inserted into the guide groove, and the control portion selectively rotating the control shaft for the relative position of the wheel housing with respect to the camshaft to be changed.

    Abstract: The present disclosure relates to a variable valve system applying a continuously variable valve timing apparatus and a two-step type variable valve lift apparatus. The variable valve system may be applied to an engine that a rotational motion of a cam being formed or disposed at a camshaft so as to rotate together with the camshaft is converted to a reciprocating motion of a valve for opening/closing a combustion chamber. The variable valve system may include the two-step type variable valve lift apparatus making a lever motion, and a continuously variable valve timing apparatus changing phase of the camshaft connected with a rotor as the rotor rotates by rotating a vane formed at the rotor. In particular, one end of the valve lift apparatus is rolling-contacted with the cam and the other end is contacted with the valve so as to realize one of two lifts of the valve.

    Abstract: An engine ventilation system may include a main blow-by passage formed at a cylinder block for communicating a crankcase with a cylinder head, a main separating passage formed in a head cover, an inflow passage drawing blow-by gas being transferred to the cylinder head through the main blow-by passage into the main separating passage, a sub-separator receiving a part of blow-by gas from the crankcase, and functioning to recollect the engine oil being collected to the crankcase, a sub-separating passage formed in the head cover, a sub-blow-by passage communicating the sub-separator with the sub-separating passage to transfer the blow-by gas passing via the sub-separator to the sub-separating passage, a main separator disposed in the head cover to separate and collect the engine oil from the blow-by gas passing through the main separating passage and the sub-separating passage, and a return outlet discharging the blow-by gas to an exterior.
