Variable Valve Timing Assembly - Description
DESCRIPTION
The world engine is equipped with Variable Valve Timing (VVT). This system advances and/or retards intake and/or exhaust camshaft timing to
improve engine performance, mid-range torque, idle quality, fuel economy, and reduce emissions. The camshaft sprockets are integrated with the VVT
assemblies and are serviced as an assembly. VVT assemblies are sometimes referred to as camshaft phasers.
