Synthetic lubricating oil can solve the dilution problem of oil and get good result.

The damage of "O" seal rings of lower bodies for fuel injection pumps is one of the reasons for oil dilution of Beijing locomotives. To solve this problem, an improvement scheme for the roller bodies of fuel injection pumps was proposed.

分析发现喷油泵下体O型密封圈破损是造成北京型机车机油稀释的原因之一，为解决这一问题，提出了一项对喷油泵滚轮体的改进方案。

The main reasons of GK 1G Series diesel shunting locomotive lubricating oil dilution were found to be long locomotive idling time, return pipe leakage, poor injector atomization quality and delivery pump seal.

通过对GK1G系列调车内燃机车机油稀释原因的分析，发现主要是由于机车怠速时间长、喷油器雾化质量差及回油管漏油、输油泵密封不良等因素造成。
