VVT-i Toyota's Intelligent Variable Valve Timing System

The VVT-i system is an acronym for Toyota's Intelligent Variable Valve Timing System. The VYT-i system has been widely installed on the latest Toyota sedan engine. Toyota's VVT-i system continuously adjusts valve timing but does not adjust valve lift.

Its working principle is that when the engine is switched from low speed to high speed, the electronic computer automatically presses the oil against the small turbine in the intake camshaft drive gear. Thus, under the effect of pressure, the small turbine is relative to the gear. The shell rotates a certain angle so that the camshaft rotates forward or backward within a range of 60 degrees, thereby changing the timing of the intake valve opening and achieving the purpose of continuously adjusting the valve timing.
