ABSTRACT:
A system for purifying the exhaust gases of a diesel engine comprises an exhaust gas line, which is branched to form two branch lines, which are adapted to be shut off in alternation by change-over valve means. One of said branch lines constitutes a filter line, which incorporates a soot filter. The other branch line constitutes a by-pass line. Downstream of the soot filter the filter line joins the by-pass line to form a common end line. In dependence on the load on the engine, the filter line is opened by the change-over valve means only during an operation of the engine under a full load or under a partial load in excess of a predetermined value. In order to ensure that the exhaust gas will almost entirely be purified during an operation of the engine throughout its load range, an diesel soot oxidation-inducing catalyst is provided downstream of the change-over valve means and is incorporated in the by-pass line or in the common end line.
