The Variable Valve Timing (VVT) system is widely used in most modern engines. It improves engine efficiency, reduces fuel consumption, and lowers exhaust emissions. A key component of this system is the camshaft phaser (cam phaser), which adjusts the camshaft's position. In an engine, the phaser is mounted on the intake and/or exhaust camshaft, and there can be one or several phasers depending on the configuration.
Different car manufacturers have their own names for these VVT systems: VVT-i, VVTL-i (Toyota, Lexus); VTEC, i-VTEC (Honda, Acura); VVL, VVEL, CVTCS, N-VCT (Nissan, Infiniti); AVCS, AVLS (Subaru); MIVEC (Mitsubishi), among others. However, all of these systems use camshaft phasers to manage valve timing.
