What is the technology and principle of cvvl?

CVVL of Pacific Auto Network is a continuously variable valve lift technology, which is a sophisticated technology in the industry. CVVL technology has brought many practical benefits to consumers, the most important of which is to reduce fuel consumption.

The traditional valve mechanism lift of the traditional engine is fixed, but the working conditions of the engine have different requirements for the valve lift. High speed and heavy load conditions require large valve lift and long duration, while low speed and light load conditions require small valve lift and short duration. However, the traditional valve train can only optimize the engine under a certain working condition and cannot meet all working conditions. CVVL technology is to solve this problem, it can adjust the valve lift, so that the engine can get the required valve lift in both high-speed and low-speed areas, thus improving the high-speed power and low-speed torque of the engine. This difficult CVVL technology can intelligently control and adjust the valve lift, so how is it realized? The CVVL mechanism controls the lifting through an eccentric shaft, an adjusting arm and a connecting arm. Firstly, the CVVL controller accurately controls the CVVL motor through the program, and the CVVL motor drives the eccentric shaft to rotate through the worm gear and worm mechanism. When the eccentric shaft rotates clockwise, the adjusting arm pushes the middle swing arm to move to the left, and the lift becomes smaller. When the eccentric shaft rotates counterclockwise, the adjusting arm pushes the middle swing arm to move to the right, and the lift increases.
