It is the "Advertised duration", used by the factory. It is the Valve timing from when the valve is .006inches off the valve seat to .006" off the valve seat.
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
IVC is Intake Valve Closing, is the crank degrees when the intake valve is closed, after TDC(top dead center).
It Means Variable Valve Timing Technology - Intelligence
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.
You mean the egr valve? Rios have precise timing with lower compression no need for an egr vale.
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.
33% of 1324 = 33% * 1324 = 0.33 * 1324 = 436.92
valve timing diagram of two stroke engine
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".
Depends on your engine, if you have the inline four then it should be 1324 if you have a v6 then is should be 123456.
