FIELD: internal combustion engines.
SUBSTANCE: internal combustion engine exhaust gases recirculation control method, wherein the internal combustion engine includes: turbocharger; the exhaust gases recirculation channel, providing the exhaust channel communication with inlet channel in part upstream of turbocharger compressor; located in the exhaust gases recirculation channel exhaust gases recirculation volume control valve; located upstream from the fresh air and gas mixture and exhaust gas fusion section in the inlet channel the differential pressure development valve; and controller, adapted to control the exhaust gas recirculation volume control valve opening and the differential pressure development valve opening, at that, in the method the controller jointly controls the exhaust gas recirculation volume control valve opening and the differential pressure development valve opening so, that to instruct the exhaust gas recirculation ratio to be changed to the exhaust gas recirculation target ratio at rate of change, which prevents abnormal combustion in internal combustion engine.
EFFECT: prevention of abnormal combustion in the internal combustion engine.
