FIELD: engines and pumps.
SUBSTANCE: invention can be used in internal combustion engines. Method of the engine operation, in which during engine (10) start-up an indication is performed of a decrease in the efficiency of valve (78) installed between crankcase (28) and intake manifold (42), on the basis of characteristics of the temporary pressure undershoot in ventilating tube (74) of the crankcase. Pressure in ventilating tube (74) of the crankcase is predicted using flow sensor (77) installed in ventilating tube (74) of the crankcase. Flow sensor (77) includes Venturi tube (75). Invention discloses the engine operating method and a system of the engine crankcase ventilation.
EFFECT: technical result is reduction of the control system complexity.
