Circuit description
The VVT system consists of engine control computer, camshaft timing oil control valve assembly, intake cam sprocket, and exhaust cam sprocket. This VVT system controls the intake cam sprocket and the exhaust cam sprocket in order to provide the best valve timing according to a driving condition. This control is based on various conditions including mass air flow, throttle position, and engine coolant temperature. The engine control computer, based on signals from these sensors, adjusts the camshaft timing oil control valve assembly. As a result, the optimal relative position of the intake camshaft is obtained, thus providing better fuel efficiency, superior output performance, and better emission performance. Also, the engine control computer detects the actual valve timing through the signal from the camshaft position sensor and performs feedback control to provide the most suitable valve timing.
