US 2015/0089931 A1 · EXHAUST GAS TREATMENT DEVICE

Abstract

An exhaust gas treatment device (1) includes a combustion waste gas inlet pipe (2), an outlet pipe, an essentially gas-tight inner housing (7) fluidically connected with the inlet pipe and fluidically connected with the outlet pipe. The inner housing receives a particle filter (4). A connection element (9) is arranged in a connection area (8) of the inner housing. The connection area fluidically faces the outlet pipe (3), for mechanically connecting the particle filter with the inner housing. An oxidation catalytic converter (5) is arranged upstream of the particle filter in the inner housing for catalyzing an oxidation reaction of the combustion waste gas. A counterpressure monitoring point (10, 11, 12) is provided fluidically between the oxidation catalytic converter and the connection element for measuring a counterpressure exerted by the particle filter during the operation of the treatment device. An internal combustion engine (24) is provided with the treatment device.
