气门间隙调整方法

气门间隙调整方法 在汽车的维护与修理中，发动机气门间隙的检查与调整是一项重要的作业内容。发动机工作过程中，由于配气机构零件的磨损或松动，或是气门在工作时因温度升高而膨胀都会导致原有气门间隙的变化。除了采用液力挺柱式(其液力挺柱的长度能通过油压进行自动调整，可随时补偿气门的热膨胀量)气门机构的发动机(如桑塔纳、捷达、奥迪100、北京切诺基213等轿车)不需要调整气门间隙以外，其它发动机一般行驶一万公里左右进行二级维护时，应检查和调整气门间隙，使之符合技术要求。 一、气门间隙 气门间隙通常是发动机处于冷态时，在气门脚及其传动机构中留有适当的间隙，以补偿气门受热后的膨胀量，这一预留间隙称为气门间隙。一般排气门的气门间隙要略大于进气门的气门间隙。 二、气门间隙调整的目的 气门间隙的大小对发动机各方面的性能影响极大:间隙过小，发动机在热态下由于气门杆膨胀可能会造成气门漏气，导致功率下降，甚至烧坏气门;间隙过大，传动零件之间以及气门与气门座之间容易产生冲撞，同时使气门开启的持续时间减少，进气和排气不充分，也会直接影响发动机的正常工作。因此，为了保证发动机的正常工作，必须调整好气门间隙。 tomorrow I go fishing to the East.

"" That is a shame 三、气门间隙调整的注意事项 气门间隙必须在该气门处于完全关闭的状态下才能进行调整。这点非常关键，否则气门间隙调整是不准确的。不同的汽车生产厂家对气门间隙的调整一般都有具体的规定和不同的技术要求，如是否在冷态或热态下调整、调整的间隙值应多大等。大多数汽车是在冷态(即冷车)调整的:如日野KM400、ZM440，别拉斯540A、138等发动机。但也有部分汽车要求在热态(即热车，水温达正常工作温度后)调整:如东风EQ1090、克拉斯221、222，丰田科罗娜RT81等发动机。还有部分汽车在冷态、热态时均可进行调整，但要求调整的气门间隙值有所不同，例如解放CA1091汽油机，黄河JN1140发动机等。 四、气门间隙调整的方法 调整时，先松开锁紧螺母和调整螺钉，将与气门间隙规定值相同厚度的塞尺插入所调气门脚与摇臂之间的间隙中，通过旋转调整螺钉，并来回拉动塞尺，当感觉塞尺有轻微阻力时即可，拧紧锁紧螺母后还要复查，如间隙有变化均需重新进行调整。通常，气门间隙调整的方法主要有逐缸调整法和两次调整法。 (一)逐缸调整法 逐缸调整法只要求将所需调整的各缸摇转到该缸压缩行程上止点(此时进、排气门完全处于关闭状态)即可对该缸tomorrow I go fishing to the East.

"" That is a shame 气门间隙进行调整。这种方法要求找到各缸压缩行程上止点，并记住各种车型发动机的作功次序(汽油机是点火次序，而柴油机为喷油次序)。例如点火次序为 1-2-4-3的汽油机 :具体调整时，先将曲轴摇转到第一缸活塞处于压缩行程上止点位置，使正时皮带轮与正时带轮罩或发动机壳上的记号对正，此时可调整第一缸的进、排气门;然后可通过观察各缸气门的升程或利用分度盘将飞轮每旋转120?，分别使各缸活塞处于压缩行程上止点位置，便可将所有气门间隙调整完毕。 有时还可使用经验法找出各缸的压缩行程上止点，从而进行气门间隙调整。例如直列式六缸汽油发动机，它的点火顺序通常为1-5-3-6-2-4或1-4-2-6-3-5。因此可将发动机分为1、2、3缸和4、5、6缸两部分。当其中的一个气缸处于压缩行程上止点时，该部分里的另外两个气缸必有一气缸处于进气行程(进气门开度最大、升程最高)，而另一气缸处于排气行程。在摇转曲轴过程中只要发现每部分中有一气缸的进气门和另一气缸的排气门同时升至最高点时，则剩下的那个气缸必定处于压缩行程上止点位置附近，此时该缸进、排气门均可调整。例如东风EQ1090发动机其点火次序为 1-5-3-6-2-4 ，若要对第2缸的气门进行调整，此时可转动曲轴，当第1缸的进气门和第3缸的排气门同时打开到最大tomorrow I go fishing to the East.
