A method of regenerating an exhaust gas purification filter, in particular for internal combustion engines, uses a vaporized liquid that is to be introduced into the exhaust gas flow. A surface temperature of a heating element in a vaporizer chamber is limited to a maximum of 700 to 750&#xb0; C.

Method of regenerating an exhaust gas purification filter, and vaporizer

A vaporizer for an exhaust system of an internal combustion engine has a vaporizer tube and a holding sleeve in which the vaporizer tube is inserted. A clamping sleeve sits on the vaporizer tube. The vaporizer tube includes two circumferentially surrounding clamping surfaces which protrude in a radial direction and cooperate with the holding sleeve and the clamping sleeve such that the clamping surfaces are clamped between the holding sleeve and the clamping sleeve by an axial clamping force to be gastight. At least one of the holding sleeve and the clamping sleeve includes a surrounding sealing edge which rests against the respective clamping surface via a line contact and forms an annular sealing seat. The vaporizer further includes a device preventing relative rotation between the holding sleeve and the vaporizer tube. A heater of the vaporizer is attached to the vaporizer tube using a resistance welding method.

An exhaust muffler of an internal combustion engine has pipe sections on the inflow side and on the outflow side, respectively, and a muffler housing that is in communication with the pipe sections. The muffler housing, which includes an outer casing and end walls, is made at least in sections of a plastic material.
