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.
