Abstract

The invention relates to a counterflow apparatus for recuperation in diesel particle filters, comprising a housing (10) with an inner casing (14), a front end surface (26) and a rear end surface (25), a front inlet (11) for cold exhaust gas (16) and a rear inlet (12) for warm exhaust gas (17). Also provided are at least two counterflow chambers (21, 23) which are arranged adjacent to one another and in which the exhaust gases (16, 17) are conducted past one another, wherein the counterflow chambers (21, 23) are separated from one another by partitions (13) and each counterflow chamber (21, 23) has at least one passage opening (18, 20) for guiding the exhaust gases (16, 17) from one portion into a further portion. Furthermore, an intermediate wall (15) is provided for separating the front exhaust-gas chamber (27) from the rear exhaust-gas chamber (22) in a gas-tight manner, and at least one outlet opening (24) for the cold exhaust gas and at least one outlet opening (19) for the warm exhaust gas (17) are provided on the housing (10).
