CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE (VERSIONS) Russian patent published in 2017 - IPC F02B29/04 F01P7/14 

FIELD: engines.

SUBSTANCE: invention relates to internal combustion engine control device. Internal combustion engine includes high-temperature intercooler (HT intercooler) with water cooling of intake air, injected by turbo compressor. Intercooler contains HT intercooler, in which passing through cylinder block cooling water is introduced, and low-temperature intercooler (LT intercooler), receiving LT cooling water with temperature lower, than HT cooling water temperature, wherein low-temperature intercooler is end to end connected close to high-temperature HT intercooler inlet side. LT target temperature is set to high-temperature side target value in case, when temperature of HT cooling water, supplied to HT intercooler, is lower, than HT target temperature, connected with completion of warming up, wherein LT target temperature is set to low-temperature side target value in case, when temperature of HT cooling water is equal to or higher, than HT target temperature.

EFFECT: invention provides reducing period of time required for internal combustion engine warming up.
