柴油机发生油水混的关键件是机体。采用先进的绝对压力式气压检测技术代替落后的水压检测方法，合理制定压差Δｐ 值，泄漏率ＶＬ 值。对机体出现的“薄壳现象”，提出铸造和机加工工艺改进方法，调整检测参数，彻底解决了柴油机产生油水混现象。
Diesel engine oil and water mixing the key pieces of the body. The use of advanced absolute pressure gas pressure detection technology to replace the backward water pressure detection methods, reasonable pressure drop Δp value, the leakage rate VL value. On the body of the “shell phenomenon”, proposed casting and machining methods to improve and adjust the detection parameters, completely solve the phenomenon of diesel oil mixed with water.
