Exhaust camshaft phasing on a VVT (variable valve timing) engine is the adjustment of the exhaust camshaft(valve timing) to what the cylinder needs at that rpm/load to improve power/eff. or emissions.


What does VVT in vectra sri mean?

Variable Valve Timing. This means the valve timing self adjusts to set the optimum time they open and shut to maximise engine fuel/power efficiency.

What does VVT mean?

VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota, similar in performance to the BMW's VANOS. The Toyota VVT-i system replaces the Toyota VVT offered starting in 24 December 1991 on the 5-valve per cylinder 4A-GE engine. The VVT system is a 2-stage hydraulically controlled cam phasing system. The Toyota motors CEO has been reported to have said, "VVT is the heart of every modern Toyota!"[citation needed]VVT-i, introduced in 1996, varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt, scissor-gear or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust valve closing and intake valve opening result in improved engine efficiency.[1] Variants of the system, including VVTL-i, Dual VVT-i, VVT-iE, and Valvematic, have followed.


Where is the egr valve on a 2005 corolla?

There is no EGR valve on this generation of Corolla. This engine is equipped with VVT-i (variable valve timing with intelligence), that allows it to perform the function of EGR without the former EGR hardware.

What is code p1354 for Lexus rx 300?

It depends on the year of your RX. 2000 and older it is a VVT malfunction. VVT stands for variable valve timing. Check the filter screens on both your oil control valves, this is often the root of VVT issues. If it is 2001 and newer it is a Control Ignition or Misfire code. Hope that helps.


What is VVT you?

its were a combustion engine has valves being open or closed for different amouts of time at different rpm. it stands for Variable Valve Timing. sometimes engines get choked of air or lose fuel and air from the combustion chamber before it is burnt so VVT fixes this
