Title:
逆流ハウジングを有する排気ガス後処理ユニットおよび排気ガス後処理のための対応するプロセス
Document Type and Number:
Japanese Patent JP2007506893
Kind Code:
A
Abstract:
An exhaust gas after-treatment unit, in particular for use close to an internal combustion engine of an automobile, includes a housing which contains at least one catalytic converter surrounded by at least one substantially free flow-through return flow region. The catalytic converter has first and second end surfaces and hollow spaces through which a fluid can flow in an inflow direction. The first end surface is connected to at least one gas feed line and at least one gas removal line is substantially gas-tightly connected to the return flow region. At least one flow deflector effects a deflection of the fluid from the catalytic converter into the return flow region of the housing. The exhaust gas after-treatment unit has a compact construction, improved start-up properties and lower thermal alternating stresses as compared with conventional exhaust gas after-treatment units.
