Express-control of oil for prevention of internal combustion engine breakdowns in oil-and-gas machinery and equipment

Abstract

One of the objectives of technical diagnostics is enhancement of remaining life prediction accuracy. The article considers the problem of the change of cylinder-piston group wear intensity in internal combustion engines of transport and transport-technological machines as a result of motor oil water cut influence. In the operational process mass fraction of water in oil contributory to the increase of wear debris amount grows because of different reasons. As a result, motor oil dielectric permittivity changes, that in its turn permits to estimate indirectly remaining life of cylinder-piston group in internal combustion engines of transport and transport-technological machines. The research was carried out on transport and transport-technological machines exploited in Omsk region. The results derived allow drawing a conclusion that taking into account water cut factor permits to assign conducting technical diagnosis of internal combustion engines in proper time and thereby to reduce amount of unexpected breakdowns.One of the objectives of technical diagnostics is enhancement of remaining life prediction accuracy.
