Abstract
In order to remove particulate matter from the exhaust gases which flow into the turbine impeller scroll of a internal combustion engine turbocharger, a separator which settles or centrifugally separates the solids from the gases is disposed between the engine manifold and the turbocharger. The separator is arranged to communicate with the turbocharger waste gate so that collected particulate matter is carried out of the device when the valve is opened to vent excessive back pressure.
