摘要

Engine exhaust system with a catalyst (7) in a housing (4) having sensors (8, 9) in its inlet and outlet zones comprises means for preventing condensed liquid from coming into contact with the sensors, either in the form of areas in which the liquid can be stored or in the form of contact elements that heat up to condensation-preventing temperature faster than the housing wall in the inlet and outlet zones.
