METHOD OF PRELIMINARY HEATING TO FACILITATE COLD START OF INTERNAL COMBUSTION ENGINE WITH SUPERCHARGING AND/OR DEVICE FOR NEUTRALIZATION OF EXHAUST GASES Russian patent published in 2019 - IPC F02D41/06 F02N19/00 

Abstract RU 2693572 C2

FIELD: internal combustion engines.

SUBSTANCE: invention relates to control over the combustion engines. Result is achieved by the fact that for heating of supercharging air in idle state of engine in intake channel there is a device for cold start. Internal combustion engine includes at least one working cylinder, which has at least one inlet valve, which is in connection with inlet channel, and at least one outlet valve, which is in connection with exhaust gas exhaust system, as well as device for setting position of valves. There is possibility of supercharging of engine by means of supercharging device intended for actuation by means of electric motor. In the method after recognition (S1) of cold start of internal combustion engine following stages are performed: switching on device to facilitate cold start in idle state of engine (S2), switching on operation by means of supercharging device (S3) electric motor and unit (S4) of valves shutoff at least between one inlet valve and at least one working cylinder outlet valve, in order to supply at least part of supercharging air heated by means of device for facilitating cold start of supercharging air directly to exhaust gas removal system by means of supercharging device.

EFFECT: technical result is to facilitate cold start of internal combustion engine with supercharging and/or device for neutralization of exhaust gases of internal combustion engine with supercharging by means of preliminary heating.
