    Abstract: A continuously variable valve timing apparatus may include a camshaft, a first and a second cam portions having two cams formed thereto, of which the camshaft is inserted thereinto, and of which relative phase angles with respect to the camshaft are variable. First and second inner brackets transmit rotation of the camshaft to the first and second cam portions respectively. First and second slider housings having first and second inner brackets are rotatably inserted thereinto, respectively, and have relative positions with respect to the camshaft that are variable. A cam cap rotatably supports the first and second cam portions together with a cylinder head, and the slider housings are slidably mounted thereto. A control shaft is disposed parallel with the camshaft and selectively moves the first and the second slider housings, and a control portion selectively rotates the control shaft so as to change positions of the inner brackets.

    Abstract: The present disclosure provides a system and a method for controlling valve timing of continuous variable valve duration engine. The method includes: classifying control regions depending on engine speed and engine load; applying a maximum duration to an intake valve and controlling valve overlap between the intake valve and an exhaust valve in a first control region; applying the maximum duration to the intake valve and reducing the valve overlap by using exhaust valve closing (EVC) timing in a second control region; advancing intake valve closing (IVC) timing according to an increase of the engine load in a third control region; controlling a throttle valve to be fully opened and controlling the EVC timing to an angle after top dead center in a fourth control region; and controlling the throttle valve to be fully opened and controlling the IVC timing according to the engine speed in a fifth control region.

    Abstract: The present disclosure provides an engine with an oil supply system including a cam carrier in which a camshaft support hole is formed and in which an oil supply hole is formed to the camshaft support hole; a camshaft in which a camshaft oil line is formed, in which an inlet supplying oil from the cam carrier oil supply hole is formed and in which a first camshaft bifurcated line is formed; first and second cam portions on which cams are formed, of which the camshaft is inserted thereto, of which relative phase angles with respect to the camshaft are variable, disposed corresponding to a first and a second cylinders, and the first and second cam portions in which a cam portion oil line in fluid communication with first camshaft bifurcated line is formed.
