Which is better, continuous variable valve timing technology or electronic throttle?

These are completely two concepts. First of all, you have to find out what these two terms mean. Continuously variable valve timing is a technology to change valve timing, and electronic throttle does not need throttle line. The accelerator pedal position sensor sends a signal to the engine computer to control the electronic throttle actuator motor to open the throttle at a certain angle. These are two completely different parts, which can be owned by a China car at the same time ... There is nothing better!
