Abstract: 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° C.

Abstract: An exhaust system for a motor vehicle comprises a particulate filter, upstream of which an oxidation catalyst is provided, and a regeneration device for the particulate filter. The regeneration device includes an evaporation unit for introducing a vapour generated from an oxidizable fluid into the exhaust gas stream before the oxidation catalyst. The evaporation unit includes a heating element arranged in a housing and a fluid supply with a controllable fluid pump. A control device controls the fluid pump. This invention furthermore relates to a process for regenerating a particulate filter.

Abstract: A motor vehicle includes a diesel propulsion engine and an exhaust system that comprises a discontinuously regenerating exhaust gas purification system. A fuel evaporator unit serves to enrich engine exhaust gases with fuel vapors. The fuel evaporator unit is connected to a vehicle fuel tank, and is provided upstream of the exhaust gas purification system. The fuel evaporator unit includes a fuel evaporator in the form of a heat exchanger that is exposed to the exhaust gas stream. The heat exchanger has a fuel feed line and a fuel vapor discharge. The fuel evaporator unit also includes an auxiliary oxidizing converter connected upstream of the heat exchanger. A percentage of nonburned diesel fuel in the exhaust gases fed into the auxiliary oxidizing converter is adjustable using an enrichment device.

Abstract: A motor vehicle includes a diesel propulsion engine having an exhaust system. The exhaust system includes a discontinuously regenerating exhaust gas purification system including a catalytic converter unit for burning diesel fuel catalytically and a fuel evaporator unit connected upstream of the catalytic converter unit. The fuel evaporator unit includes an electrical heating element and is connected to the fuel tank of the vehicle by a fuel line. The fuel evaporator unit is spatial from any exhaust gas carrying components. A fuel vapor feeding channel upstream of the catalytic converter unit discharges into an exhaust gas carrying component and extends between the fuel evaporator unit and an exhaust gas carrying component.
