DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, Oil Control Valve (OCV) and VVT controller. The ECM sends a target duty-cycle
control signal to the OCV. This control signal regulates the oil pressure supplied to the VVT controller. Camshaft timing control is performed
according to engine operating conditions such as intake air volume, throttle valve position and engine coolant temperature. The ECM controls the
OCV, based on the signals transmitted by several sensors. The VVT controller regulates the intake camshaft angle using oil pressure through the
OCV. As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust
