What does DVVT on the engine mean?

DVVT stands for Dual Variable Valve Timing, which refers to the technology of variable timing for both intake and exhaust valves. 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: Reduces intake and exhaust overlap, ensuring stable combustion; Decreases intake loss, improves fuel consumption, and enhances fuel economy by 24%; Effectively reduces emissions of hydrocarbons and nitrogen oxides; Delivers stronger engine power, with a 12% increase in performance.
After driving for so many years, DVVT is simply a marvel in my engine. DVVT stands for Dual Variable Valve Timing, which means it allows the engine to automatically adjust the opening and closing times of the intake and exhaust valves based on the engine speed. At low speeds, it closes slightly to save fuel, and at high speeds, it opens wider to boost power. This is very noticeable in my daily commute. Previously, a full tank would last 450 kilometers, but now it can go over 500 kilometers, and the power delivery is smoother. Especially when climbing hills, the throttle responds quickly with just a light press. I remember on my last long trip, fuel consumption was nearly 10% lower, emissions were reduced, and the exhaust test was a breeze. Nowadays, most new cars come with this feature, and the mechanic said it rarely malfunctions during maintenance. It's truly perfect for cost-conscious drivers like us.
