ABSTRACT:
An exhaust gas recirculation control method for controlling the recirculation of exhaust gases through an exhaust gas recirculating passageway communicating an exhaust passage of an internal combustion engine for vehicles and an intake passage of same, in response to operating conditions of the engine. The range of the exhaust gas recirculation effecting region of the engine, which is determined by the engine rotational speed and another engine operation parameter indicative of intake air quantity, is varied in response to changes in the vehicle speed. The above exhaust gas recirculation effecting region is defined as a region wherein the engine rotational speed lies between a first predetermined value and a second predetermined value higher than the former, and the above another engine operation parameter shows a value lying between a first predetermined value and a second predetermined value representing an intake air quantity larger than that represented by the first predetermined value thereof on condition that the engine rotational speed remains constant. Preferably, the range of the exhaust gas recirculation effecting region is reduced as the vehicle speed decreases. Further preferably, as the vehicle speed decreases, the above second predetermined value of the another engine operation parameter is set closer to the first predetermined value thereof, and/or the above first predetermined value of the engine rotational speed is set higher values.
