ABSTRACT:
In a device for determining an exhaust gas recirculation rate (EGR) in an internal combustion engine, wherein the device includes a sensor unit, which in a first region is exposed to an exhaust-gas atmosphere from an exhaust gas recirculation line and in a second region is exposed to an exhaust gas/fresh air atmosphere in an intake line of the internal combustion engine downstream of a location where the exhaust gas recirculation line opens into the intake line, the sensor unit disposed in the intake line is tubular with the inner side of the sensor unit being exposed to the exhaust gas atmosphere and the outer side of the sensor unit being exposed to the exhaust gas/fresh air atmosphere. The sensor unit is preferably positioned centrally within the intake line away from the wall of the intake line.
