Vehicle with diesel engine with discontinuously regenerated exhaust gas purification system using fuel vapour injection

摘要

A vehicle, with a diesel motor, has an intermittently regenerated exhaust gas cleaning system in the exhaust gas assembly, with a catalyst section (4) which burns diesel fuel followed by a particle filter (8). A fuel evaporation unit (11), in front of the catalyst (6), has an electrical heater, and is linked to the fuel tank (14) by a fuel feed line (12). The fuel evaporation unit is positioned with space between it and the exhaust gas outflow system, with a channel to feed fuel vapor into the exhaust gas, upstream of the catalyst.
