What is variable valve timing and how does it affect the way the engine operates? This video is sponsored by Standard.
The latest versions continuously adjust the position of the intake and exhaust camshafts.
Learn how VVT works, why it sometimes doesn’t and how to service the system. This course is sponsored by Cloyes.
VVT systems need proper oil maintenance. This video brought to you by The Group Training Academy.
Andrew Markel discusses timing components, and how issues with the variable valve timing actuator can cause codes from misalignment.
Andrew Markel discusses the variable valve timing system, and how the behavior of oil in the system is a lot like voltage passing through a component or module.
The CMP actuator system controls the amount of intake and exhaust valve overlap. The engine control module (ECM) can only command the CMP actuator to advance the valve timing from the park position or retard the valve timing back to the park position.
One of the ways automakers squeeze more horsepower and torque from an engine is adding variable valve timing (VVT) to the valvetrain.
Variable valve timing is becoming a standard system on most late-model engines because it offers higher performance from a smaller displacement engine at higher rpms. Oil plays a larger role in VVT systems. They need engine oil not only for lubrication, but also to actuate the camshafts to change the profile of the lobes.
