摘要： A method for automatically setting valve clearances in internal combustion engines (also known as "tappet setting" or "valve lash setting") comprises a series of steps in which a rocker arm (10) is set to a zero position which is recorded as a reference datum and an adjustment screw (18) is then operated to set the rocker arm to a first reference position. The adjustment screw is then rotated through a predetermined angle so that the rocker arm is moved to a second reference position. The difference between the first and second reference positions and the predetermined angle are used to determine a coefficient relating the angular movement of the adjustment screw to linear movement of the rocker arm. The coefficient is then used to calculate the angular rotation of the adjustment screw required to set a predetermined valve clearance relative to the zero position. The initial adjustment of the rocker arm position serves to neutralise backlash in the valve drive train prior to setting the valve clearance.

摘要翻译： 一种用于在内燃机中（因此称为“挺杆设置”或“式气门间隙调节”）自动地设定阀间隙的方法包括一系列在哪一个摇臂（10）被设置到零位置步骤的所有被记录为一个 参考日期和调整螺钉（18）然后操作到摇臂设置为第一基准位置。 调节螺钉然后通过旋转预定角度所以做了摇臂移动到第二基准位置。 所述第一和第二参考位置和预定的角度之间的差被用于确定性地挖掘的系数与所述调整螺钉的角运动到摇臂的线性运动。 然后，将系数用于计算预定相对于零位置的阀间隙的设定所需要的调节螺钉的角旋转。 摇臂位置的初始调节用于前设定阀间隙neutralisé在阀传动系统反冲。
