What does the engine technology CVVL mean?

CVVL engine refers to an engine that employs Continuous Variable Valve Lift technology. Traditional engines have fixed valve lift, but actual operating conditions require different valve lift levels, leading to certain limitations in conventional valve mechanisms. This has given rise to Variable Valve Lift (VVL) technology. Engine introduction: 1. An engine is a machine capable of converting other forms of energy into mechanical energy. Engines include internal combustion engines, external combustion engines, jet engines, electric motors, etc., applicable both as power generation devices and as entire machines including power units. 2. Engine displacement is the total working volume of all cylinders in an engine, commonly available in configurations such as 3-cylinder, 4-cylinder, 6-cylinder, 8-cylinder, 10-cylinder, and 12-cylinder.
The car I test drove last time used CVVL technology, which stands for Continuous Variable Valve Lift. Simply put, it intelligently adjusts the valve opening depth. Traditional engines have fixed valve openings, like a water pipe with only two settings—either fully open or half open. CVVL, however, can adjust continuously like a faucet, allowing the engine to breathe more smoothly at different speeds. At low speeds, it opens slightly to save fuel, while during acceleration, it opens fully to deliver maximum power. This not only improves fuel efficiency but also reduces emissions. Many domestic engines now incorporate this technology, such as the XX 1.5T model, which has been tested to be about 10% more fuel-efficient than conventional engines.
