TEMPERATURE REGULATING METHOD AND DEVICE OF INTERNAL COMBUSTION ENGINE Russian patent published in 2011 - IPC F01P7/16 

FIELD: engines and pumps.

SUBSTANCE: engine temperature regulating method and device is proposed. Device includes valve device (3) located in section (11) of internal combustion engine (1) cooling system loop, which connects engine (1) to radiator (2); at that, in this section (11) of loop between engine (1) outlet and valve device (3) inlet there located is temperature sensor (101), and valve device (3) has the possibility of automatic opening under influence of heating with cooling fluid to the specified temperature. According to invention the device includes devices (31) of changing the specified temperature in compliance with certain specified profile lying in the range between minimum (C1) and maximum (C2) set temperature values stored in memory so that engine temperature can gradually reach minimum or maximum set value for attenuation of heat impact owing to maintaining relative wide opening of valve device, and control devices (45, TC) of the first opening of valve device.

EFFECT: reducing fuel consumption and also quantitative emission of toxic pollutants.
