Kia Sportage: Engine Control System / E-CVVT motor Description and operation

Electric E-CVVT system is electric continuous variable valve timing system. It is located on the intake camshaft of the engine and uses motor rotation to control the rotation angle of camshaft relative to the rotation of crankshaft regardless of engine pressure. E-CVVT controls the DC motor current (duty signal) to more closely control the system compared to the previous pressure type, to increase reaction speed of cam, to improve startability, and to reduce the emission of exhaust gas. Also, operation range of intake valve (valve opening angle) is expanded. So, the output and fuel efficiency are improved.
