Abstract:
A device for exhaust gas recirculation from an outlet region (4) of a motor vehicle internal combustion engine (1) into an air intake region (2), comprising a regulator (15) for adjusting a mixture of exhaust gas and in-flowing air mass feedable to the engine, a first flow rate sensor (14) for determining the mass of the in-flowing air mass, and a fuel feed for introducing to the engine an amount of fuel adjustable as a function of the air mass in-flow rate taking a performance specification signal into consideration, wherein the outlet region (4) is connected with the intake region (2) of the internal combustion engine (1) via a flow channel (6) for the exhaust gas recirculation, the flow channel (6) having at least one temperature sensor (16), one controllable valve (5) as an adjustment member, and a second flow rate sensor (10).
