OPERATING METHOD OF OIL CIRCULATION CIRCUIT, IN PARTICULAR, FOR VEHICLE Russian patent published in 2020 - IPC F01M5/00 F01P7/14 

FIELD: technological processes.

SUBSTANCE: invention relates to a method of operating an oil circulation circuit, in particular for a vehicle, wherein by means of said oil circulation circuit (5), an internal combustion engine (7) is provided with oil (8), wherein this oil circulation circuit (5) has at least one oil cooler (15), by means of which oil (8) flowing along the oil circulation circuit (5) is cooled, and wherein at least one temperature sensor (39) is provided, through which the temperature of oil (8) flowing through the oil circulation circuit (5) is measured, in particular, downstream of oil cooler (15) and upstream of internal combustion engine (7). According to the invention, temperature sensor (39) according to the signal technology is connected to the control and/or control device (11, 13, 43, 35), by means of which oil (8) temperature is controlled and/or controlled by the oil circulation circuit (5), so that the temperature measured by temperature sensor (39) has a given nominal temperature value (T_nom.). In particular, to reduce the consumption of engine fuel (7) of the internal combustion nominal value (T_nom.). Temperature is set and/or rearranged by device (11, 13, 43, 35) regulating and/or control, depending on drive power (P_pref.), in particular depending on driving torque and/or depending on internal combustion engine (7) rotational speed.

EFFECT: invention provides reduced fuel consumption of an internal combustion engine.
