Variable Valve Timing with Intelligence
variable valve timing is where the engine changes valve timing based on the driving situation much like ignition timing is changed to meet the needs of the engine in specific situations. in most cars valve timing is static and determined by the timing gear on the camshaft
Valve timing is not adjustable on a stock engine. The timing chain is either installer correctly or not.
This component is electrically operated by the engine computer. It (on most vehicles) changes the oil pressure in the variable valve timing system to adjust the valve timing. It is very similar to the solenoids in use inside an automatic transmission.
It is a 3.6 Liter engine with variable valve timing (VVT).
on the engine exhaust cam ..at the front of the cam .
im pretty sure this is variable valve timing. So at different RPM the computer will adjust the valve timing to suit the load on the engine and mave the engine more fuel efficient
According to Wikipedia, a variable valve timing is a "process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions".
Variable Valve Timing. This means the valve timing self adjusts to set the optimum time they open and shut to maximise engine fuel/power efficiency.
Exhaust camshaft phasing on a VVT (variable valve timing) engine is the adjustment of the exhaust camshaft(valve timing) to what the cylinder needs at that rpm/load to improve power/eff. or emissions.
