Which Honda models are equipped with VTEC?

[ArthurRose]

Here is a brief introduction about Honda's i-VTEC: 1. Honda's i-VTEC system can continuously adjust valve timing and also regulate valve lift. 2. Its working principle is: when the engine transitions from low to high speed, the computer automatically directs oil pressure to the small turbine inside the intake camshaft drive gear. 3. Under this pressure, the small turbine rotates a certain angle relative to the gear housing, causing the camshaft to rotate forward or backward within a 60-degree range. This changes the timing of the intake valve opening, achieving continuous adjustment of valve timing.
