在发动机燃油系统发现大量的粘稠油泥铁锈
原因一、挖掘机操作人员违反了挖掘机加注柴油规定。
为了加快加注柴油速度和缩短加油时间,减轻手握加油枪的力量,就将燃油箱内的粗滤网去掉,将加油枪直接塞入燃油箱内加油。
由于在更换储油罐时没有对油罐进行清洗,没有对所剩柴油进行过滤,油罐底部所剩柴油较脏,含有大量沉淀油泥、石蜡、油污和铁锈,造成了发动机燃油系统污染,燃油滤清器似堵非堵,导致了挖掘机失速故障的发生。 
防范措施
液压挖掘机的发动机燃油系统故障预防措施及避免维修间接损失的建议2.1发动机燃油系统故障预防措施
1.液压挖掘机要加注清洁的燃油,应不含水、沙、硫、金属及其他杂质。燃油应符合质量标准的规定。应尽量避免在运输、储存、使用过程中加入被污染的燃油。
2.对发动机燃油系统应经常进行检查,发现有破损、裂纹、变形、堵塞的滤芯和滤网必须更换。
3.定期检查并清洗发动机燃油系统,校准喷油泵及喷油嘴。
4.严格按《操作与保养说明书》规定时间更换燃油滤清器。
5.应使用本机原装燃油滤清器,不得使用仿冒伪劣的燃油滤清器。
