ABSTRACT:
A branched exhaust system having a particular filter in at least one branch thereof has valves in each branch operable by control means to route exhaust gases along any selected branch. Thus when the filter in one branch requires regeneration that branch can be closed. The control means is also operable in response to an exhaust braking demand signal to maintain all valves closed so as to at least restrict the flow of exhaust gas and so apply back pressure to the engine; to apply exhaust braking.
