What does DVVT on the engine mean?

[RowanAnn]

DVVT stands for Dual Variable Valve Timing, which refers to the technology of variable valve timing for both intake and exhaust. Engines equipped with DVVT technology are more efficient, energy-saving, and environmentally friendly compared to those using only intake valve timing technology, which is more commonly found in the market. The advantages of DVVT engines are as follows: 1. Reduces intake and exhaust overlap, ensuring stable combustion; 2. Decreases intake loss, improves fuel consumption, with fuel economy increased by 24%; 3. Effectively reduces emissions of hydrocarbons and nitrogen oxides; 4. Enhances engine power, with a power increase of 12%.
