What does the CVVT system do in the Kia Rio?

I've heard about the CVVT system in the Kia Rio but I'm not sure what it actually does. Can someone explain it to me?

The CVVT system, or Continuous Variable Valve Timing, is an engine technology used in the Kia Rio that control the opening and closing of the valves in the engine. It helps to improve fuel efficiency and engine performance.

The CVVT system is important because it allows for more precise control over the timing of the valves, which can increase power and reduce emissions. It's a great feature in the Kia Rio that sets it apart from other cars in its class.

As a Kia Rio owner, I can tell you that the CVVT system is a great addition to the car. Not only does it improve performance and fuel efficiency, but it also helps to reduce engine noise and vibrations. It's a must-have feature.
