Summary:
- This article discusses the differences between Variable Valve Timing (VVT) and Variable Valve Lift (VVL), two technologies used in modern car engines.
- VVT allows the engine to adjust the timing of the opening and closing of the valves, which can improve efficiency and power output. VVL, on the other hand, adjusts the amount of lift the valves have, which can also enhance engine performance.
- The article explains how these technologies work and how they can be used together to optimize engine performance for different driving conditions, such as low-speed and high-speed operation.
