Beschreibung
Zusammenfassung:	The present disclosure provides a reductant injection system for an SCR catalyst of an internal combustion engine, the reductant injection system comprising at least one injector, a first storage container for storing liquid reductant and a pump for pumping reductant from the first storage container to the injector for injection into an exhaust gas stream, wherein the injector is cooled by reductant. The reductant injection system may comprise a second storage container for storing liquid reductant and is configured such that the injector can be cooled by reductant from the second storage container.
