ABSTRACT:
Engines that include different combustion strategies for different cylinders may create a power imbalance resulting in undesirable engine vibrations. The engine system of the present disclosure includes a first engine that is operable to produce a high NOx concentration exhaust and a second engine that is operable to produce a low NOx concentration exhaust. The first engine is fluidly connected to a first section of an exhaust passage and the second engine is fluidly connected to a second section of the exhaust passage. The exhaust from the first engine and the exhaust from the second engine are merged in a merged section of the exhaust passage downstream from both the first and second sections of the exhaust passages. The high NOx concentration exhaust may be converted to ammonia for reacting with the low NOx concentration exhaust to arrive at very low NOx concentration from the merged exhaust.
