What does VVT engine mean?

[FaithLee]

vvt engine is an engine equipped with vvt variable valve timing system. The system controls the opening and closing time of the valve and the valve timing through the engine's computer control unit and the solenoid valve, which is the execution unit. As a result, the valve opening and closing time varies with the engine speed to improve the charging efficiency and increase the engine power. Here is more information about the VVT engine: 1. Operation principle: The driving computer detects the engine's operating conditions and sends instructions to the solenoid valve to adjust the intake volume, intake angle, and valve opening and closing time, so that the intake air volume reaches the optimum and the combustion efficiency is improved. 2. Advantages and disadvantages of VVT engine: The advantages of vvt engine are fuel saving and high power per liter, while the disadvantage is insufficient torque at medium speed.
