![](http://i.vdolady.com/uploads/allimg/170930/201709301702155651.jpg"></a> </p> <p>发动机在工作中，有很多因素都会引起发动机积炭，所谓积炭就是汽油或者机油与氧气在高温下作用后形成的产物。汽缸盖积炭会降低发动机冷却效果；活塞顶部积炭会引起发动机“爆燃”、“爆震”以及加剧磨损减少发动机寿命；而气门及气门座圈上有积炭则会降低气缸的气密性从而会让发动机出现动力孱弱的表现。如果你的爱车上了一定年限，积炭不得不除。</p> <div class="commodity_con_small2"><a href=http://www.vdolady.com/plus/tao_jump.php?itemid=550377493009>

![](http://i.vdolady.com/uploads/allimg/170930/201709301702155655.jpg"></a> </p> <p>发动机的动力来源于连续不断的汽油燃烧迸发的能量，而燃烧则需要几个条件，其中氧气量就是一个重要的指标。如果进气量不足也会导致发动机软弱无力，没有足够的进气量，燃油在发动机内就无法得到充分的燃烧，而最容易引发进气问题的原因为节气门和空气空气滤清器没有及时清洗和更换。</p> <div class="commodity_con_small2"><a href=http://www.vdolady.com/plus/tao_jump.php?itemid=526016119981>
