由于量具不足,过去我们在维修缸盖时经常碰到一些具体情况不能正确处理。例如有的气门下沉量还在允许范围内就换掉了气门座圈,这是一种浪费;有的气门下沉量已经超过极限,却还在继续使用,这就会使发动机功率不足。为正确测出气门下沉量,在量具不足的情况下,我们采取了以下简易方法:将缸盖及所有气门上的积炭和油泥全部清除干净,把需要检查下沉量的气门装入该缸原来的
Due to the lack of measuring tools, in the past we often encounter some problems in the maintenance of cylinder head can not be properly handled. For example, some valve sinking is still within the allowed range to replace the valve seat, which is a waste; some valve sinking has been over the limit, but still continue to use, which will make the engine power shortage. In order to correctly measure the valve sinking amount, in the case of lack of measuring tools, we have taken the following simple method: the cylinder head and all valves on the coke and sludge all clean, the need to check the amount of sink valve into the Cylinder original
