What does VVT mean on a Toyota?
Variable Valve Timing-intelligent
Tokyo―TOYOTA MOTOR CORPORATION announced today the development of its new “Variable Valve Timing-intelligent” (VVT-i) technology, which increases performance and fuel economy. Engine development today necessitates both better fuel economy and advanced vehicle performance.
Is the VVT-I a good engine?
There are many benefits to using VVT and virtually no drawbacks. One benefit is an increase in maximum engine speed (and therefore more peak power) – as much as a 25% increase. Low speed torque is also increased, providing better handling and drivability.
Are Toyota dual VVTI engines good?
Toyota’s Dual VVT-i technology adjusts both the intake and exhaust valves, which makes the system more efficient and assists in reducing emissions even further. The practical upshot of this for the driver is more power, better responsiveness, better mileage, and lower emissions.
Is a VVTi 2JZ?
2JZ. The 2,997 cc (3.0 L; 182.9 cu in) 2JZ has been produced since 1991 (first released in the 1991 Toyota Aristo). Cylinder bore and stroke is 86 mm × 86 mm (3.39 in × 3.39 in). VVT-i variable valve timing was added later in 1997 for the 1998 model year.
How long does Toyota VVT engine last?
A Toyota engine can last between 250,000 to 300,000 miles, just as the average Honda engine can last up to 300,000 miles.
How many cylinders is a Toyota VVTi?
4-Cylinder
The VVT-i system varies the timing of the intake valves by adjusting the relationship between the camshaft drive and intake camshaft. This is a Toyota 4-Cylinder Gas Engine with Variable Valve Timing (VVT-i) and Indirect Injection.
At what RPM does VVTI kick in?
It’s counterpart, the 2zz-ge, which is the engine used in the GT-S, has the VVTL-i technology. That extra “L” in there gives you the kick at 6000 rpm’s (6200 in later models), known only as lift.
How long does Toyota VVTI engine last?
What is the Toyota VVT-i system?
The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 5-valve per cylinder 4A-GE engine. The VVT system is a 2-stage hydraulically controlled cam phasing system.
What is the VVT system on a Toyota Crown?
The VVT system is a 2-stage hydraulically controlled cam phasing system. VVT-i (introduced on the 2JZ-GE engine in 1995 on the JZS155 Toyota Crown and Crown Majesta) varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt or chain) and intake camshaft.
What is the Dual VVT i system?
The Dual VVT-i system adjusts timing on both intake and exhaust camshafts. It was first introduced in 1998 on the RS200 Altezza’s 3S-GE engine. Dual VVT-i is also found in Toyota’s new generation V6 engine, the 3.5-litre 2GR-FE first appearing on the 2005 Avalon.
What does VVT-i stand for?
