    摘要: 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.
