EXHAUST SYSTEM FOR A MOTOR VEHICLE AND PROCESS FOR REGENERATING A PARTICULATE FILTER IN AN AUTOMOTIVE EXHAUST SYSTEM

摘要

The invention relates to an exhaust gas installation of a motor vehicle, comprising a particle filter (16) and an oxidation catalyst (18) mounted upstream thereof as well as an regeneration device for said particle filter (16), said regeneration device comprising an evaporating unit (20) for introducing vapour which has been generated from an oxidizable liquid into the exhaust gas before the oxidation catalyst (18). The evaporating unit (20) comprises a heating element (24) mounted in a housing, a liquid feed duct (26) provided with an adjustable liquid pump (28), as well as a regulating device (30) for regulating the liquid pump (28). The invention also relates to a method for regenerating a particle filter (16).
