Haa, korang tahu tak perbezaan antara enjin VVT, VVTi, dengan Dual VVTi? Biasa enjin ni ada dalam kereta model Toyota dan Perodua.Follow kami di📸 Instagram C.

VTEC = VVTL = Lift, where a second more aggressive cam is lifted into play resulting in more power top end. iVTEC and VVTLi = uses both cam phasing and cam lifting. VVT-iE (Variable Valve Timing - intelligent. by Electric motor) is a version of Dual VVT-. i that uses an electrically operated. actuator to adjust and maintain intake. camshaft timing. [2] The exhaust camshaft. ftiming is still controlled using a hydraulic. actuator. This form of variable valve timing. The main difference between VVTi and Dual VVTi is that VVTi technology adjusts the timing of the intake valves only while Dual VVTi adjusts both intake and exhaust valves (double-acting). In 2015, the 2TR-FE was upgraded, which resulted in the introduction of the Dual VVT-i variable valve timing system (before that, the phase shifters were only at the intake) and the compression ratio was increased from 9.6:1 to 10.2:1. The simple design and time-tested components make the 2TR-FE engine one of the most reliable Toyota engine. Vay Tiền Nhanh Ggads.
