在保养和检修四行程多缸内燃机时,调整各气缸的气门间隙是很重要的一项工作。为了提高工作效率,通常采用两次调整气门间隙法。具体调整步骤如下: 一、确定内燃机各气缸的工作顺序。一般技术资料上都有注明。实在没有资料可查时,亦可根据有关方法确定之,具体方法从略。二、确定各气缸的进、排气门排列位置。可查阅有关技术资料,亦可根据气门的开、闭动作顺序确定之,具体方法从略。三、确定首段和尾段的首缸压缩上止点记号。压缩上止点记号一般设在曲轴末端的飞轮和飞轮壳上,
In the maintenance and repair of four-stroke multi-cylinder internal combustion engine, the adjustment of the valve clearance of each cylinder is a very important task. In order to improve work efficiency, usually adjust the valve clearance twice. Specific adjustment steps are as follows: First, determine the working order of the cylinder of the internal combustion engine. General technical information has been marked. In fact, no information is available for investigation, but also according to the relevant methods to determine the specific methods omitted. Second, determine the cylinder inlet and exhaust valve arrangement position. Can consult the technical information, but also according to the valve opening and closing action to determine the order, the specific method omitted. Third, determine the first paragraph and the end of the first cylinder compression TDC mark. Compression top dead center mark is generally located in the flywheel and flywheel housing at the end of the crankshaft,
