Abstract
An exhaust system for an internal combustion engine is connected to an outlet of the internal combustion engine and has a particulate filter. A differential pressure line for ascertaining the particulate filter load connects a section of the exhaust passage upstream from the particulate filter and a section of the exhaust passage downstream from the particulate filter to a differential pressure sensor. At an end of the differential pressure line facing the exhaust passage, a reservoir which serves to collect condensate protrudes into the exhaust passage and can be heated up by the exhaust gas in the exhaust passage. Due to the heating of the reservoir, the liquid that has collected in the reservoir evaporates and can be introduced in gaseous form into the exhaust passage through an opening in the reservoir, so that the risk of droplet formation in the exhaust passage is avoided.
