Honda VTEC Engine Technology Introduction Honda Motor Company is DigiPlusone of the world's famous automobile manufacturing enterprises, and it has always maintained a leading position in the history of automobile development. Among them, the VTEC engine technology developed by the company is a model of its innovation, which aims to improve the fuel economy and performance of automobiles. VTEC Engine Technology Introduction VTEC is the abbreviation of Variable Valve Timing and Lift Electronic Control. The Chinese name is Variable Valve Timing Electronic Control Technology.It is an automobile engine control technology introduced by Honda Motor Company since the 1980s. The original design of this technology is to improve engine performance and achieve higher fuel economy. The valve of the traditional engine is controlled by the timing mechanism connected to the camshaft. If you want to change the opening timing and lift of the valve, you need to replace the camshaft. The VTEC engine changes the timing and lift of the valve through electronic control, so as to achieve more accurate valve control. The VTEC engine has two different valve timing, one for low speed and the other for high speed. At low speed, the engine supplies gas to the cylinder with a low-rise valve timing; when the engine speed increases, the control system automatically switches to the high-rise valve timing. This automatic switching methodIt can balance the fuel economy of low speed and the power performance of high speed, so that the engine can get the best power output under various working conditions. Compared with traditional engines, VTEC engines have the advantage of higher fuel economy: the valve timing of the VTEC engine can accurately control the air intake volume and intake time through electronic control, making the fuel combustion more complete, thus improving the fuel utilization rate. During driving, when the load of the engine is small and the speed is not high, the low-rise valve timing can effectively improve fuel economy. Better power output: The VTEC engine uses a high-rise valve in high-speed mode, which can make the fuel fully burn, thus outputting greater power and making the vehicle perform better under acceleration, overtaking and other conditions. Better reliability: VTEC engine throughThrough electronic control, the precise timing and lift of the valve can effectively avoid the problems of incomplete combustion, cylinder burst and other problems caused by unreasonable valve timing and lift, and improve the reliability and durability of the engine. Summarizing the application of VTEC engine technology, it provides new ideas and space for the development of Honda. It not only improves fuel economy and performance, but also broadens the breadth and depth of the technological field of the automobile industry. With the progress of science and technology and the development of the market, VTEC engine technology will continue to play an important role in the automobile manufacturing industry, bringing people a more comfortable and safe driving experience.
