Continuous Variable Valve Timing (CVVT)



Continuous Variable Valve Timing (CVVT)







The Engine Control Module (ECM) infinitely variable controls the CVVT valve which in turn controls the CVVT unit with engine oil pressure.

The CVVT unit is mounted on the exhaust camshaft and the intake camshaft. The CVVT unit is used on all 5-cylinder engines.

The variable camshaft main task is to minimize exhaust emissions, mainly at cold start, but also gives an improved idling quality.
