FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to internal combustion engine exhaust gases recirculation systems. Control method of internal combustion engine (10) including EGR channel (27) connecting outlet channel (13) with inlet channel (12). Negative pressure control valve (44) is located in the part of inlet channel (12) upstream of the EGR-channel and inlet channel (12) fusion and is made with possibility to open and close inlet channel (12). At that, the internal combustion engine (10) control method includes the stages, at which the negative pressure control valve (44) is controlled so that to provide the differential pressure between outlet channel (13) and inlet channel (12), when operating state of internal combustion engine (10) is in EGR-area, in which EGR-gas is recirculated into inlet channel through EGR-channel (27). Control valve (44) of negative pressure control in closing direction is controlled and opening of negative pressure control valve (44) is controlled so that volume of air passing through negative pressure control valve (44) exceeds or is equal to target volume of sucked air, when operating state of internal combustion engine (10) is in working area with lower load than EGR-area, wherein target volume of sucked air is set based on operating state of internal combustion engine (10). Also disclosed is internal combustion engine control device.
EFFECT: technical effect consists in suppression of noise generation during combustion.
