What does the 180DVVT engine mean?

[OBraxton]

180DVVT refers to a 1.5L displacement. DVVT stands for Dual-Variable-Valve-Timing, which means dual variable valve timing technology for both intake and exhaust valves. Engines equipped with DVVT technology are more efficient, energy-saving, and environmentally friendly compared to engines that only use intake valve timing technology, which is more commonly found in the current market. Additional information is as follows: 1. Principle: The DVVT engine operates on a principle similar to that of the VVT engine, utilizing a relatively simple hydraulic cam system to achieve its function. The difference is that VVT engines can only adjust the intake valves, whereas DVVT engines can adjust both intake and exhaust valves, offering excellent characteristics of high torque at low RPM and high power at high RPM, placing it at the forefront of technology. 2. Advantages: The benefits of DVVT technology include a reduction in fuel consumption by 0.05, an increase in power by 0.1, achieving the optimal air-fuel ratio by controlling the mixture of gasoline and air in the engine's combustion chamber, and significantly improving idle stability, thereby enhancing overall comfort.
