What is a VVT-i 16 valve engine?

VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. 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. via

Is a VVT-i engine good?

VVT-i advantages include increased torque and output, better fuel economy, and reduction of nitrogen oxide (NOx) and hydrocarbon emissions. The simple structure of the VVT-i makes it extremely reliable and easy to adapt for existing engine designs. Wide applications of the new technology are expected in the future. via

Which one is better VVT-i or VTEC?

In conclusion, the i-VTEC engine by Honda is more potent than rival Toyota's VVTi when it comes to being ore powerful at high RPMs; it is also close to being economical at low RPMs like the VVTi tech. via

What does VVT-i means in a car?

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. via

Is VVT-i better than non VVT-i?

Basically so far the pro's of the vvti are that it makes more torque at half the rpm compared to the non vvti, it's a newer engine so less wear and already comes single turbo. via

Is VVT-i a petrol or diesel?

1.33l Dual VVT-i Petrol Engine

It generates 73 kW/ 99 DIN hp and maximum torque of 128 Nm at 3,800 rpm. Mated to a six-speed manual transmission, this excellent dynamic performance is combined with fuel consumption of just 5.6 l/100 km and CO2 emissions lowered from 136 to only 129 g/km. via

How long does Toyota VVT-i engine last?

The average Toyota engine will last between 250,000 miles to 300,000 miles. via

Does VVT save fuel?

VVT and related lift systems help to improve combustion. That leads to better operation of the engine, lower emissions and a 1 to 6% reduction in fuel consumption. via

What cars have VVT engines?

Proprietary Terms for VVT

  • Alfa Romeo - Twinspark technology.
  • Audi - VVT.
  • BMW - Valvetronic, VANOS and Double VANOS.
  • Ford - Variable Cam Timing.

  • Lexus - VVT-iE.
  • via

    Are Toyota dual VVT-i 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. via

    What is dual VVT-i?

    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. via

    When did the 2JZ GTE VVTi?

    The VVTi 2jzgte came in JZA80 Supra from September 1997 – July 2002. via

    What is the difference between Ivtec and VTEC? (video)


    Do diesel engines have VVT?

    The VVT system was applied to boost the engine output. In diesel engines, the full torque depends essentially on the amount of charge air, and the VVT system is effectively used to increase the charge air amount by making use of the pressure pulsation in the exhaust and intake ports. via

    Can you turbo a VVT engine?

    Your engines VVT settings will vary depending on your engine platform, turbo choice, manifold runner design, exhaust backpressure, etc. Newer and more efficient turbocharges will happily improve performance with added overlap during spool up, cruise, and even full throttle with some combinations. via

    How much horsepower does a VVT-i have?

    Engine Choices

    1.8L 4-Cylinder DOHC 16-Valve with Dual Variable Valve Timing with intelligence (VVT-i): This engine option delivers an impressive 132 hp and 128 lb-ft of torque. via

    What is the advantage of variable valve timing?

    The main advantage of having a variable valve timing technology is the increase it will provide in your engine's revolutions per minute. When you step on the gas pedal to accelerate the vehicle, your engine will be capable of a higher RPM which generally translates to more power (to a point). via

    What's the difference between VVT-i and dual VVT-i?

    Basically, single VVT-i means the engine has variable valve timing on the inlet cam only, whereas the dual VVT-i has variable timing on both the inlet and exhaust cams. via

    How does Toyota VVT-i engine work?

    Toyota's VVT is a cam phasing system, which is one of the most common in use. It uses a variator, which is hydraulically-controlled, to change the size of the inlet and exhaust valve openings, which also affects the duration of those openings as well. via

    What is the difference between EFI and VVT-i engine?

    EFI simply means the engine is fuel injected and that's been the standard since the early 1990s. VVTI is Toyota's variable valve timing engine design that allows for variable timing of the camshaft. via
