Abstract

An injector (1) for injecting fuel and an additional fluid, is provided in that the injector (1) is designed for optimal space-saving yet exhibiting a simple construction. This construction results in a precise injection of a fuel and an additional fluid into a combustion chamber of an internal combustion engine. The arrangement has two solenoid valves, the first valve (2) and the second valve (3). The second solenoid valve (3) has a second nozzle needle (9) which is arranged in the injector (1), and the first nozzle needle (7) of the first solenoid valve (2) and the second nozzle needle (9) of the second solenoid valve (3) are arranged one behind the other on a longitudinal axis (10) of the injector (1). Further, the nozzle needles (7, 9) can be controlled independently of one another.
