초록 ▼

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.

A system for purifying exhaust gas of a diesel engine, comprising an exhaust line, two branch lines comprising a filter line and a by-pass line, respectively, and arranged downstream of said exhaust line, a soot filter incorporated in said filter line, a common end line, which is connected to said filter line downstream of said soot filter and to said by-pass line, change-over valve means, for connecting said exhaust line in alternation only to said filter line and only to said by-pass line, valve-actuating means, for operating said change-over valve means in dependence on the load on said engine so that they connect said exhaust line only to said filter line when said engine is operating under a load in excess of a predetermined load, which is lower than its full load, and so that they connect said exhaust line only to said by-pass line when said engine is operating under a load which is not in excess of said predetermined load, an oxidation-inducing catalyst for diesel soot downstream of said change-over valve means and incorporated in one of said by-pass or common end lines, and heat-conductive means for interconnecting said soot filter and said oxidation-inducing catalyst.
