Abstract

An exhaust gas treatment system for a diesel engine 110, the system comprising a selective catalytic reduction system (SCR) and diesel particulate filter (DPF) installed in the exhaust line 275 of the engine with one injector 10 installed in the exhaust line for injecting hydrocarbon (HC) and a urea catalyst, which are supplied by a first and a second pump respectively 11, 12, where the system further comprises at least one valve 15 for controlling the flow of the hydrocarbon and the urea catalyst into the injector. Preferably the valve is a two-way control valve with two operating positions, where the two pumps are connected to the inlet of the valve and the injector is connected to the outlet such that the first position of the pump delivers hydrocarbon and the second position delivers urea. A method of operating the system is also claimed.
