A motor vehicle internal combustion engine EGR loop, in which: with the fresh air flow rate in the air inlet path (2) of the EGR valve (1) set at a maximum, the path (3) for the EGR gases in the valve is progressively opened, and before the EGR gas flow rate in the valve increases any further, the fresh air inlet path (2) is progressively closed in order to continue to cause the EGR gas flow rate to increase on an increasing monotonous curve. |
