共轨油咀0433171931喷油器0445115007

当挖机出现P0191、P0192、P0193等时，说明共轨压力传感器异常。可以检查传感器是否松动以及线束是否松动。如果还未确定，可通过以下方法判断：

使用万用表，测试各端子间的电阻，若电阻值超过标准值，则需要更换共轨柴油喷射装置。

检查柴油机油底壳机油油位

柴油机应尽量保持在水平状态停机检查机油油位。拉出油标尺用干净纱布擦干后将油标尺插到底，然后再次拉出，检查油位显示是否在油标尺尾端上限和下限刻线之间。如果油位接近下限刻线或低于下限刻线，必须立即加注机油，且尽可能使油位达到上限线。如油面超过上限刻线过多则应从油底壳螺塞放出多余机油，否则油面过高机油将从前后油封中溢出

空气滤清器的保养

和及时地保养空气滤清器，防止灰尘进入气缸中对柴油机缸套、油塞、油塞环、气门等的工作寿命十分重要。空气滤清器的保养周期应根据工作环境的含尘情况决定。使用环境恶劣的尘土飞扬地区，保养周期应短，反之可适当延长。空气滤清器上装有堵塞指示器。如果是电感式指示器驾驶室信号灯亮后必须保养空气滤清器。对装有机械式堵塞指示器的空滤器，则应将柴油机油门踩至空车高速运转，观察保养指示器如已处在红格位置，则应保养滤芯。

The week-long event will reinvigorate trade activities between the two countries in the new digital economy. We are looking forward to welcoming you at the First UAE-China digital expo.

Automechanika Shanghai 2020 will take place on 2-5 December at the National Exhibition and Convention Center. Being a global platform for the 8AUGK po@china-lutong.net industry, the trade show will attract major players from more than 140 nations. Over 6500 companies will present services and innovations across the entire automotive supply chain.

目前常用的纸质二级空滤器有主滤芯和安全滤芯二个滤芯。保养空滤器时先拧下盖上的螺母打开空滤器盖，取出滤芯将壳体内的尘土清理干净。用手或木棒轻轻敲击滤芯两端，边敲边转动滤芯，将灰尘振落。也可用不大于600kPa的清洁压缩空气从滤芯内侧小心向外吹拂，将灰尘除掉。同时检查安全滤芯（在主滤芯里面的小滤芯）是否亦有灰尘需作相同保养。
