/>     今天立特松挖掘机l修厂小~详l的冒黑烟故障的发生原因、现象以及处理方式教l大Ӟ聪明的老司机别忘记收藏Q?br />     故障现象<br />     ▊进气不x者进气管路泄露导致的黑烟现象Q因挖掘机长旉使用Q进气胶及卡老化损坏会导致管道漏气、吸入灰较大、空冷器堵塞{都会造成冒黑烟现象?br />     出现q种问题Q应该及时处理解冻I不然发动Z出现早期损Q甚x~等故障?br />     ▊如果发动机冒黑烟大Qƈ且动力下降比较大Q就需要检查涡轮增压器q气内有没有漏油现象,涡轮增压器的涡轮叶轮Q叶片有无断裂、磨损、变形的情况出现Q涡轮增压器壳体内是否有划痕损伤Q叶轮u间隙是否过3毫米?br />     如果有以上这些现象就必须更换涡轮增压器?br />     ▊检查柴Ҏ܇、喷油器是否有磨损而造成的冒黑烟现象Q发动机在冒黑烟时挖掘机q有力,但是发动{速会掉?过200??br />     q种现象主要是柴油嘴出现的故?可用断实验Q检查喷油器的好?Q若qx挖掘机冒黑烟q启动困Nl常加注启动Ԍq种现象需要检查柴Ҏ܇?br />     ▊如果发动机EGR阀损坏或者卡M会造成冒黑烟现象,如果EGR阀出现故障Q显C器会出现报警提C?br />     出现该故障要及时更换Q不然会影响发动机的使用效率Q而且能明显感觉到比正常工作耗a更多?br />     ▊发动机冒黑烟时挖掘机无力,发动载工作时有变音现象,此时很可能是液压泵功率超q了发动机功率所D的冒黑烟?br />     此时先降低液压܇量及压力,如果液压泵调整到正常值后故障依然存在Q那必L查发动机燃apȝ了,如果无法降低液压泉|量及压力Q那么就需要检查液压系l部件?br />
