Criteria for the Discard of Lubricants,

Abstract

In science and technology there is no unified opinion about the times to change the lubricating oil in high-pressure marine engines. The optimum service life of oil depends on operating conditions and technical state of the engine, number of starts, types of fuel and oil, oil additives, quality of servicing, etc. so that it has become necessary to set up criteria for getting rid of oil. In Soviet river navigation, the main parameters chosen to determine the quality of oil are: increase in physical contaminants, presence of water, and change in viscosity. To support these criteria, observations were made of the changes in the oil in 35 marine engines. Special lubricating systems were designed and appropriate tests were made. (Author)
