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.


Components
Appearance of E-CVVT is similar to that of hydraulic CVVT. Connector that drives
DC motor and protection cover that protects the motor are mounted on the upper
part. D ...
