Description & Operation: Description
- 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 start-ability, and to reduce the emission of exhaust gas.
- Operation range of intake valve (valve opening angle) is expanded. So, the output and fuel efficiency are improved.
