发动机在使用中需要经常地检查和调整气门间隙。一般是逐缸调整,需要多次转动曲轴,逐缸确定活塞位于压缩行程上止点的位置,这样费时费力,特别是对于多缸柴油机这样工作起来更为困难。下面介绍一种调整气门的新方法,用转动曲轴二次,可以调完全部气门。一、简述调整气门间隙必须使挺杆完全落下,即挺杆的下平面落到凸轮的基圆上,这样调整气门间隙才是准确的,所以凸轮外廓形状上的基圆部分构成了气门间隙可以调整的部分,简称可调带。
The engine needs to be regularly checked and adjusted for valve clearance. Generally adjusted by the cylinder, the need to rotate the crankshaft several times, by cylinder to determine the piston compression stroke at the top dead center position, so time-consuming and laborious, especially for multi-cylinder diesel engine to work more difficult. Here’s a new way to adjust the valve, use the crankshaft twice, you can tune all the valves. First, a brief description of the adjustment valve clearance must be fully tapped tappet, tappet under the plane fell on the base circle of the cam, so adjust the valve clearance is accurate, so the shape of the basic outline of the cam contour part of the valve Gap can be adjusted part, referred to as adjustable belt.
