Claim Text:
1. An exhaust gas treatment device comprising: an outer housing; an inlet pipe, connected to the outer housing, for admitting a combustion waste gas; an outlet pipe, connected to the outer housing, for discharging the combustion waste gas; a particle filter; an essentially gas-tight inner housing connected with the inlet pipe and connected with the outlet pipe, the gas-tight inner housing for receiving the particle filter, the gas-tight inner housing being arranged at least partially within the outer housing; a connection element arranged in a connection area of the gas-tight inner housing, said connection area fluidically facing the outlet pipe, the particle filter being pushed completely into the gas-tight inner housing and the connection element mechanically connecting the particle filter with the gas-tight inner housing at a downstream end of the particle filter; an oxidation catalytic converter, arranged in the gas-tight inner housing upstream of the particle filter, for catalyzing an oxidation reaction of the combustion waste gas; and a counterpressure-measurement fluidic connection from an exterior of the gas-tight inner housing to an interior of the gas-tight inner housing and provided fluidically between the oxidation catalytic converter and the connection element for measuring a counterpressure exerted by the particle filter during operation of the exhaust gas treatment device.
