On most 4 cylinder Nissans, the solenoid for the VVT is located at the front passenger side of the cylinder head.
It is a 3.6 Liter engine with variable valve timing (VVT).
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.
8 it has a 4.5 litre 32 valve DOHC VVT engine Pushing around 300 HP. And yes I know they were rated at 278 in the US. It was underated by Nissan to meet some standard for exporting.
Variable valve timing.
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.
no need to externally fitted EGR .Reason VVT have valve actuate various angle depends engine speed that time valve overlapp is high . in end of exhaust stroke both valve open condition exhaust gas easy to mix with fresh air . it acting on same as EGR
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.
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.
Yes Toyota vehicles with a 3.3L V6 engine that has VVT-i have timing belts.

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
