ABSTRACT:
A method for removing particulates from internal combustion exhaust gases in a system which includes a first gas conduit which connects with an engine exhaust pipe and which communicates with a series of trap chambers containing means for filtering or trapping particulate matter present in the exhaust gas. Means for heating gas passing through said first gas conduit is provided upstream of the first trap chamber. A second gas conduit connects with said first gas conduit at a location upstream of the first trap chamber by virtue of which exhaust gas can be made to flow in a path which by-passes any number of trap chambers in the series but which flows through subsequent trap chambers. Valve means are associated with said second gas conduit to selectively by-pass or direct exhaust gas flow through desired trap chambers.
