摘　　要：利用光谱分析技术,通过对78台NJ2型机车近5年来柴油机机油中铁、硅、硼、钠4种元素含量的测定,得出诊断NJ2型机车柴油机出现早期渗漏水故障的界限值,并据此提前发现17台机车柴油机出现渗漏水情况。Using spectral analysis method and through the content measurement of Fe, Si, B and Na in oil of diesel engines for 78 locomotive's in recent 5 years, the limit value of early water leakage fault of NJ2 locomotive's diesel engine is obtained. According to the result, the water leakage faults of 17 locomotive's diesel engine were found in advance.
