What is the function of the Audi valve lift system?

I'm curious about how the Audi valve lift system works, but I'm not sure what its purpose is. Can someone explain it to me?

The Audi valve lift system is a technology that allows for better engine efficiency by adjusting the amount of air intake into the cylinders. In simpler terms, it helps the engine perform at its best in different driving conditions, whether it's for power or fuel economy.

I've found that the Audi valve lift system can also improve the overall performance and responsiveness of the engine, as well as reduce emissions. It's a smart technology that makes a big impact on the engine's performance.

The Audi valve lift system works by varying the valve lift height, which controls the amount of air and fuel that enters the combustion chamber. This allows for optimal airflow and combustion, resulting in better engine performance and efficiency.
