IC695CRH015

IC695CRH015排气冒黑烟主要有以下原因：

1．高压油泵供油量过大或各缸供油量不均匀

2．气门密封不严，造成漏气，气缸压缩压力低

3．空气滤清器进气道阻塞、进气阻力大，使进气量不足

4．缸套、活塞、活塞环严重磨损

5．喷油器工作不良

6．发动机超负荷运转

7．喷油泵供油提前角过小，燃烧过程后移到排气过程进行

8．汽油电喷系统控制失效故障等

对于冒黑烟的发动机可通过高压油泵调校，喷油器喷射试验检查，气缸压缩压力测量，进气道清洁，供油提前角的调整、汽油电喷系统故障诊断等工作予以检查和排除。

柴油发动机排气冒白烟的故障原因

排气中的白烟主要是未充分雾化和燃烧的燃油颗粒或水汽，因此，凡是导致燃油无法雾化或水进入气缸内都会使排气冒白烟。归纳主要有以下原因：

1．气温低且气缸压力不足，燃油雾化不好，特别是冷起动初期排气冒白烟

2．缸垫损坏，冷却水渗入气缸内

3．缸体裂，冷却水渗入气缸内

4．燃油中含水量大等
