In recent years, there has been a trend of increasing activities in the development of polar territories. Negative temperatures are a characteristic feature of the North. Negative temperatures have a negative impact on the state of power installations of land, air and water transport, mobile, stationary power plants and small-scale mechanization facilities. The engine is least adapted unit for operation in such conditions. There is a chain of negative factors that consistently provides a connection between the state of the lubrication systems and the negative temperatures, in which the equipment is operated. Condensation processes are a primary link in this chain. The existence of condensation processes in the crankcase space when a piston engine is warmed up at negative temperatures is experimentally proved. The percentage of engine oil watering and the dew point temperature of crankcase gases are determined in the conditions of a full-scale experiment. However, the high labor intensity and significant financial costs of organizing such experiments require the search for other methods of testing. A mathematical representation of reality, which allows you to obtain objective and adequate experimental data information, can be one of the ways to solve this problem.
