Pollutant i.e. nitrogen oxide, emission controlling method for diesel engine of vehicle, involves operating engine in operating mode according to calibration minimizing rejections of carbon dioxide by engine

摘要

The method involves associating a combustion engine with an exhaust line (9) comprising a nitrogen oxide reduction catalyst (15) and a particle filter (18) in a direction of exhaust gas flow. Fuel is injected in combustion chambers of a combustion engine during regenerations of the particle filter in a point of an exhaust line located between the nitrogen oxide reduction catalyst and the particle filter. The engine is operated in an operating mode according to a calibration minimizing rejections of carbon dioxide by the engine. An independent claim is also included for a power train comprising a combustion engine.
