Abstract

The efficiency of using of mineral engine oil modifier to restore compression of the cylinder–piston group of internal combustion engines is investigated. According to the results of full-scale tests of four different automobiles operating in an urban environment, the effect of increasing the compression of the cylinders to 20%, compared with the original, and reducing the pressure difference between them up to four times, was determinated. The effect reached a stable value after a run of 2000–4000 km and remained until the end of the experiment (10 000 km). It was found that when implementing the recommended procedure for flushing the engine before using oil with a friction modifier (FM), complete engine failure can occur. According to preliminary data the probability of this event is 20–30%.

根据运行测试结果，摩擦改性剂在内燃机中的使用效率

摘要

研究了使用矿物机油改性剂恢复内燃机气缸-活塞组压缩的效率。根据对在城市环境中运行的四种不同汽车的全面测试结果，与原始相比，将气缸压缩率提高到20％，并将它们之间的压力差降低至原来的四倍，其效果是确定的。在运行2000–4000 km后，效果达到稳定值，并一直保持到实验结束（10000 km）。结果发现，在使用建议的冲洗程序并在使用带摩擦改进剂（FM）的机油之前冲洗发动机时，可能会导致发动机完全故障。根据初步数据，该事件的可能性为20％至30％。
