ABSTRACT:
An exhaust gas filter, such as a soot filter for a diesel engine, is provided with a filter body disposed in a housing. The exhaust gases flow through the filter body to be cleaned. The filter also has an inlet duct and an outlet duct. Between the inlet duct and the outlet duct, there is disposed one or several lateral lines for passing gases along the outside of the filter body. Both ends of the lateral lines are connected via apertures to the inlet duct and the outlet duct, respectively. The cross sections of the inlet duct, outlet duct and the lateral lines are selected so that in the unloaded condition of the filter body a return flow in the lateral lines is produced, while a bypass flow is produced when a preselected loading condition of the filter body is reached.
