<p>The internal combustion engine for reducing emissions of unburnt hydrocarbons and a nitrogen oxides, comprises a cylinder, an exhaust gas line (2) for discharging the exhaust gas from a cylinder, an oxidation catalysator (3) for the oxidation of the carbon monoxides present in the exhaust gas and the unburnt hydrocarbons, a storage catalysator (5) for storing and reducing the nitrogen oxides present in the exhaust gas, a particle filter (6) for collecting and burning carbon black particles in the exhaust gas, an upstream of a four-way catalysator (1) and an additional oxidation catalysator. The internal combustion engine for reducing emissions of unburnt hydrocarbons and a nitrogen oxides, comprises a cylinder, an exhaust gas line (2) for discharging the exhaust gas from a cylinder, an oxidation catalysator (3) for the oxidation of the carbon monoxides present in the exhaust gas and the unburnt hydrocarbons, a storage catalysator (5) for storing and reducing the nitrogen oxides present in the exhaust gas, a particle filter (6) for collecting and burning carbon black particles in the exhaust gas, an upstream of a four-way catalysator (1) and an additional oxidation catalysator intended in the exhaust gas line. A combined exhaust gas subsequent treatment system is intended as four-way catalysator in the cylinder. Means are intended, with which an enrichment of the exhaust gas with reduction agents is realizable by internal motoric measures to reduce nitrogen oxides stored in the storage catalysator.</p> |
