摘要
A heat exchanger system for treatment of a flow of exhaust gases in an exhaust gas aftertreatment system of a vehicle. The heat exchanger system includes a nitrogen monoxide (NO) oxidation site for oxidizing nitrogen monoxide to nitrogen dioxide (NO2). The NO oxidation site is positioned such that the flow of exhaust gases at a downstream end (40) of the NO oxidation site in use of the heat exchanger system is arranged to proceed at a temperature within a predetermined temperature interval corresponding to a desired NO to NO2 (NO:NO2) ratio interval in the flow of exhaust gases. An exhaust gas aftertreatment system and a vehicle including such a heat exchanger system, and a method for using such a heat exchanger system, are also provided.
