Supplying with water the motor oil at KAMAZ-740 engine’s warming at low temperatures

Abstract

The article dwells upon the problem of supplying with water the motor oil of engine at warming under negative temperatures (-32 ° C). There is described an experiment for measuring the concentration of water in the KAMAZ-740 engine’s motor oil, in the process of its warming without preheater. As a result of condensation processes occurring in the engine there is fulfilled an accumulation of water in the lubrication system, accompanied by the set of negative consequences. During the experiment, the temperature is determined in the amount of crankcase space corresponding to the drop point temperature.
