Abstract
Thermal shock reactions of a heated lambda probe owing to the impact of liquid droplets on the heated ceramic probe body during cold starting, which phenomenon can lead to a fracture of the ceramic probe body, are avoided, and a better representativeness of the signals transmitted by the lambda probe is achieved, in that a gas deflector plate is arranged before the lambda probe in the exhaust gas flow, as seen in the direction of flow of the exhaust gases, in such a way that the lambda probe lies in its Lee.
