ABSTRACT:
A compact device is provided for sampling particles from the exhaust gases of an internal combustion engine for an automotive vehicle. The device includes a dilution tunnel, to which is supplied all the exhaust gases of the internal combustion engine. From the dilution tunnel, by way of an exhaust gas distributor, a sample stream of exhaust gas is distributed to filter cylinders arranged in exhaust gas conduits in dependence on the operation of the internal combustion engine. Filter units, traversed by the sample stream of exhaust gas, are removably disposed in the filter cylinders which are vertically arranged and exhibit a filter mounting element accommodating the filter units. This filter mounting element is adapted to be swung out laterally from the filter cylinders after opening of a locking device. A plurality of filter cylinders are provided, each being associated with a specific operating phase of the internal combustion engine, and being utilized for determination of the quantity of emitted particles. A filter cylinder designed as a static cylinder is also provided. Upstream and downstream of each filter cylinder, valves are arranged which are adapted to control the flow of exhaust gas through the individual cylinders.
