Kia Sportage: Cylinder Head Assembly / CVVT & Camshaft 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 start ability, 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.
