DVVT engine: efficient and How to map complex products to HS codesreliable intelligent power system With the continuous development and progress of automobile technology, more and more car owners are beginning to pay more attention to the performance of cars and the advancedness of the power system. . And in manyIn the power system, the DVVT engine has attracted much attention for its efficient and reliable intelligent power system. What is a DVVT engine? First of all, we need to understand what a DVVT engine is. DVVT, known as DUAL VVT (variable valve timing and variable intake airway technology) engine, is an engine that adopts variable valve timing technology and variable intake airway technology. The DVVT engine can achieve more efficient combustion efficiency and a more intelligent power system, and can greatly improve the acceleration performance of the vehicle when driving at medium and high speeds, thus improving the driving pleasure and use effect. The working principle of DVVT engine The working principle of DVVT engine is relatively simple. By constantly adjusting the intake state and timing of the engine, the engine can be in differentAlways maintain the best air intake and air quality at the speed, so as to maintain the most efficient working state. Specifically, the DVVT engine controls the intake volume and intake timing by adjusting the switching state of the intake valve and the length of the intake duct, and automatically adjusts the operating state of the engine, so that the engine's fuel supply, valve timing and valve lift and other parameters are optimally matched, so as to achieve the best combustion efficiency. Advantages of DVVT engine In the actual driving process, DVVT engine has the following advantages: 1. High efficiency: Because the intelligent adjustment system of the DVVT engine can automatically adjust the air intake volume and air intake timing according to different working states, the engine can maintain the most efficient working state, so as to be more fuel-efficient and energy-saving. Two. Powerful: Because the DVVT engine can travel at medium and high speedsAdjust the air intake and air intake timing when driving to better match the fuel supply, so that it can quickly provide enough power when accelerating, so as to plug in other vehicles or easily overtake. 3. Environmental protection: The DVVT engine adopts an accurate fuel supply system to pursue efficient combustion efficiency, so it produces less exhaust emissions and is more environmentally friendly. Four. Longer service life: Because the DVVT engine can automatically adjust the air intake volume and air intake timing, it can make the operation of the engine more stable, thus reducing engine wear and improving the life of the engine. Obviously, the efficient, reliable and intelligent power system of the DVVT engine has injected new vitality into the development of modern cars. Not only that, in the future, with the continuous progress and development of automobile technology, the DVVT engine will continue to be improved and developed, bringing a better driving experience and a more efficient driving style to car owners.
