Are Toyota VVTi engines good?
The VVTi mechanism is not unique to the land cruisers. It’s pervasive across the whole lineup of toyota’s and has proven it’s worth reliability in power and gas efficiency. Look at the pros – more power and efficiency across the board. That’s not something to be taken likely for a heavyweight car like the Land Cruiser.
What is a VVT 16 valve engine?
VVT-i stands for Variable Valve Timing-Intelligence, which is Toyota’s name for the variable valve technology it uses in most of its vehicles. Some variable valve systems also work on the exhaust valves, which open to let the air-fuel mixture out of the engine.
Is 16 valve a v6?
No. 16 is not a multiple of six so a 16 valve 6 cylinder engine would have to have more valves on some cylinders than others which doesn’t make much sense. A four stroke engine needs at least 2 valves per cylinder, one inlet and one exhaust.
What is dual VVTi Toyota?
Their latest application is Dual VVT-i (Variable Valve Timing with intelligent) technology. The technology is a smarter ways that could make engine more efficient and more eco-friendly. The sistem is located on the cylinder head which is used as automatic time controller of the engine’s inlet and exhaust valves.
How good is 1ZZ engine?
1ZZ-FE engines offer 120-140 horsepower, so it’s certainly not an impressive performance engine. However, the Toyota 1ZZ FE does offer a good balance of reliability and efficiency. No engine is perfect, though, and there aren’t any exceptions here.
What size engine is a Toyota VVT-i?

The 2.5-liter engine employs Dual independent Variable Valve Timing with intelligence (VVT-i), which controls timing on both the intake and exhaust camshafts (compared to the intake-only previous 2.4-liter engine).
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 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 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.
Why did Toyota stop making the VVTL-i engine?
Toyota has now ceased production of its VVTL-i engines for most markets, because the engine does not meet Euro IV specifications for emissions.
