In an arrangement for the dosed injection of a reducing agent into the exhaust tract of an internal combustion engine, comprising a pump for the pulsed pumping of the reducing agent and an atomizing injection nozzle disposed in the exhaust tract of the internal combustion engine, the injection nozzle includes a valve element which opens and closes the injection nozzle depending on the pressure generated by the pump and permits the injection of the reducing agent into the exhaust tract only when the pressure of the reducing agent is in excess of a certain value in order to ensure proper atomization of any reducing agent injected into the exhaust tract.

Arrangement for the dosed injection of a reducing medium into the exhaust tract of an internal combustion engine

A fuel injector for internal combustion engines having a control valve arranged upstream of a main flow valve is configured so that the connection leading over the control chamber between the inlet and outlet, which is regulated by the valve member of the control valve, directs the function of a throttle position, among other things, by way of a limit stop of the control piston against the front wall overlapping the control chamber for the purpose of reducing control leakage.
