我变,我变变变!在整体硬件不做太大改变的情况下,将这根直径不超过5公分的小气门的升降做出调整,可以让发动机在燃油经济性方面拥有明显的变化。将气门升程集成到发动机电脑上,做出智能化控制序列,起到的是四两拨千斤的效果。它的原理也很简单,主要是将发动机在市区怠速时候的状态作为特殊的工况来处理,在不影响整车稳定性的前提下,将这个时候的喷油量和排放量 I change, I change! In the case of the overall hardware does not make much change, the root diameter of not more than 5 cm to adjust the lift, you can make the engine has significant changes in fuel economy. The valve lift integrated into the engine computer to make intelligent control sequence, played a deft effect. Its principle is very simple, mainly when the engine idling in urban areas as a special condition to handle, without affecting the stability of the vehicle under the premise of this time the amount of fuel injection and emissions
