What does vvt mean?

Pacific Auto Network VVT is a variable valve timing system. The technology adopted by VVT engine is continuously variable valve timing technology. Its function is to continuously adjust the valve opening and closing time and air intake of the engine, thus improving the engine power and optimizing the torque curve. The biggest advantage is to improve engine power and reduce fuel consumption.

The principle of VVT (Variable Valvetiming) is to adjust the intake and exhaust volume, valve opening and closing time and angle according to the operation of the engine. So as to optimize the intake air quantity and improve the combustion efficiency. Its advantages are fuel saving and high lift ratio. The disadvantage is the lack of speed and torque in the middle section.

VVT technology has a history of more than 30 years. 1980, AlfaRomeo used VVT technology for the first time. Honda, 1989, used VVT technology with variable valve lift for the first time; Bmw, at 200 1, used VVT technology to replace the traditional throttle for the first time.

What does VVT mean in China variable valve timing? Because it is controlled by electronic control unit (ECU), the system mainly controls the intake camshaft and a small tail. Me? Is it English? Smart? The code name of (intelligence). Is that all? VVT-i？ The literal meaning of.
