摘要： An internal combustion engine system includes a spark-ignited internal combustion engine powered by a gaseous fuel. The engine system also includes an air intake in air providing communication with the internal combustion engine. Further, the engine system includes an exhaust system in exhaust gas receiving communication with the internal combustion engine. The exhaust system includes a methane oxidation catalyst through which at least a portion of the exhaust gas flows and an exhaust gas recirculation line in exhaust gas providing communication with the air intake.

摘要： An apparatus, system and method for reducing the emission of nitrogen oxides in an internal combustion engine system. Exhaust gas directly or indirectly downstream of the internal combustion engine is at least selectively stored in an exhaust gas storage region. Upon the occurrence of at least one enablement condition, indicative of a potential period where the emission of nitrogen oxides (NOx) will increase, the stored exhaust gas is inserted into the internal combustion engine to assist in reducing the emission of the nitrogen oxides. The exhaust gas storage volume regularly, or the exhaust gas storage volume may be filled during strategic periods when the emissions of nitrogen oxides are low and/or there is a low need for the recirculation of exhaust gas.
