MOTOR VEHICLE INTERNAL COMBUSTION ENGINE EGR LOOP

摘要

Motor vehicle internal combustion engine EGR loop in which: when the fresh air flow rate in the air inlet passage (2) of the EGR valve (1) is at its maximum, the EGR gas passage (3) in the valve is gradually opened and, before the EGR gas flow rate in the valve increases any further, the fresh air inlet passage (2) is gradually closed in order to cause the flow rate of the EGR gases to continue to increase in a monotonous increasing curve.
