dc.description.abstract Mathematical modeling of the operation processes of automotive engine oils allows to optimize the time of their use during operation. A certain significance for changing the qualitative properties of motor oils is introduced by such an operational indicator as „waste” oil consumption. The article describes the causes and parameters of engine oil consumption, as well as the mathematical model of changes in the physico-chemical properties of engine oil during operation. The one that will allow us to optimize the periodicity of replacing the engine oil, as a result this fact will allow us to increase the distance between the interventions of the corrective maintenance works of the means of transport. en_US
dc.description.abstract Modelarea matematică a proceselor de funcționare a uleiurilor de motor pentru automobile permite optimizarea timpului de utilizare a acestora în procesul exploatării. O anumită semnificație asupra proceselor de modificare a proprietăților calitative ale uleiurilor de motor este introdusă de un astfel de indicator de explaotare, precum consumul de ulei la „ardere”. În articol sunt descrise cauzele și parametrii de consum a uleiului de motor, precum și modelul matematic de modificare a proprietăților fizico-chimice ale uleiului de motor în timpul exploatării. en_US
