Exhaust system of an internal combustion engine

Abstract

An exhaust system of an internal combustion engine, in particular of a vehicle, has an insert through which exhaust gas flows, for purifying the exhaust gas, and a mixing chamber through which exhaust gas flows and which is arranged upstream of the insert through which exhaust gas flows. The mixing chamber includes at least one permeable wall and is arranged on a channel wall of the exhaust system and protrudes radially into the interior of the exhaust system. The exhaust system further has a vaporizer device that vaporizes an oxidizable liquid and introduces the vapor into the mixing chamber, and an ignition device that protrudes at least partly into the mixing chamber. The vaporizer device includes a glow element which is configured and heatable in such a way that an auto-ignition of the oxidizable vapor occurs on its surface.
