Abstract: The present inventive concept relates to an aftertreatment system for a vehicle, the aftertreatment system being connectable to an internal combustion engine, wherein the aftertreatment system comprises an oxidation catalyst, a first NOx sensor arranged upstream the oxidation catalyst, a second NOx sensor arranged downstream the oxidation catalyst, and a control unit comprising a processor device configured to determine a sensor based conversion ratio of nitric oxides to nitrogen dioxides by the oxidation catalyst from data received from first and second NOx sensor, obtain an estimated conversion ratio of nitric oxides to nitrogen dioxides by the oxidation catalyst from a model, and determine a malfunction condition of the aftertreatment system in response to the sensor based conversion ratio being different from the estimated conversion ratio, and perform a responsive action of the aftertreatment system based on the malfunction condition.

Abstract: The inventive concept relates to a method of operating a reducing agent injector, the method comprising: determining a reference level of toxic substances exhausted from a catalytic reduction arrangement when injecting reducing agent at the pre-set mass flow rate; controlling a reducing agent injector to inject reducing agent at a first mass flow rate, the first mass flow rate being different from the pre-set mass flow rate; determining a first level of toxic substances exhausted from the catalytic reduction arrangement after injecting reducing agent at the first mass flow rate; determining which one of the reference level of toxic substances and the first level of toxic substances being a lowest level of toxic substances; updating the pre-set mass flow rate of the predefined injection model to an updated pre-set mass flow rate as the mass flow rate causing the catalytic reduction arrangement to exhaust the lowest level of toxic substances; and controlling the reducing agent injector to inject reducing agent at the updated pre-set mass flow rate.
