FIELD: engines and pumps.
SUBSTANCE: invention can be used in vehicle internal combustion engines. Method for vehicle engine (10) consists in that in response to closing valve (274) of exhaust gas recirculation (EGR) system (270), (272), content of oxygen downstream of engine exhaust gases and upstream of EGR valve (274) in EGR system. When the oxygen content is lower than the threshold value, engine inlet (242) with outlet (248) is connected due fluid medium through EGR system (270), (272) by opening EGR valve (274), during operating conditions, when it would otherwise be closed, for blowing system (270), (272) EGR into inlet (242). Disclosed are versions of method for vehicle engine and vehicle engine system.
EFFECT: technical result consists in prevention of supply of exhaust gas flow with low concentration of oxygen into engine cylinders.
