DVVT（DVVT） Dual Variable Valve Timing. Means continuous Variable Timing technology of inlet and exhaust Valve. The engine with DVVT technology is more efficient, energy saving and environmental protection than the current market. Roewe 550, for example, DVVT technology can reduce fuel consumption by 5%, and power increased by 10%, to 2.0 liter power index, exhaust emissions meet the national Ⅳ grading standards; By controlling the mixture of gasoline and air in the combustion chamber of the engine to achieve the most suitable air combustion ratio, the idling stability can be significantly improved to obtain better comfort. Roewe 550 DVVT 1.8 L engine, on the other hand, is more on the basis of ordinary DVVT technology, special joint world famous auto parts manufacturer Litens developed oval variable curvature radius, timing pulleys to timing gear train low load, reduce the engine noise and vibration, in the process of vehicle driving to ensure that the car when a quieter, more comfortable. 2011 chery A3 DVVT + VIS technology combination, litres of power more than 58 kw, power of 93 kw, 1.6 L to 1.8 L displacement, and 1500 RPM can achieve 80% maximum torque, 3950 RPM maximum torque of 160 n - m, to become the most strong 1.6 L models at the same time, the ministry of integrated fuel consumption is as low as 6.5 L/hundred kilometers, enjoy the national energy saving huimin project 3000 yuan subsidy.
