The dependences of changes in the contaminant contents and base numbers of motor oil during refining are established. Finely disperse contaminant particles are enlarged if a mixture of ammonium hydroxide with 1% urea is added to working engine oil. Subsequent centrifugation with cleaning agents incorporated into the lubrication system allows almost all contaminants to be removed from the oil. The dependences of the content of insoluble precipitate and base number on the operating time in the engine of the motor oil with the added reagent is established. Periodic cleaning of engine oil by the proposed method allows the service life until replacement to be extended and the operational characteristics of the internal combustion engine to be increased.

去除工作机油中的老化产品,而无需将其从发动机曲轴箱中排出

建立了精炼过程中机油的污染物含量和碱值变化的相关性。如果将氢氧化铵与 1% 尿素的混合物添加到工作发动机油中,则细分散的污染物颗粒会增大。随后用润滑系统中加入的清洁剂进行离心,几乎可以从油中去除所有污染物。建立了不溶性沉淀物的含量和碱值与添加试剂的机油在发动机中的运行时间的相关性。通过所提出的方法定期清洁发动机油允许延长直至更换的使用寿命并且增加内燃机的操作特性。
