- the device 1 further comprises a UV light source 12, which is arranged to emit ultraviolet radiation around the water
- the water is disinfected by the provided in the device 1 cationic acid-forming metal, on the other hand, the UV light source 12 for
- the UV light source 12 may be, for example, a UV lamp or a UV LED.
- the UV light source 12 is configured to emit ultraviolet radiation.
- the UV light source 12, which generates UV radiation, is arranged in the water tank 5 in this exemplary embodiment.
- the UV light source 12 can also be arranged at other locations in the device 1. For example, it may be arranged in the lines 7, 8, 11, 13 or even a distributor 9.
- the UV light source 12 is arranged such that the water of the device 1, which is to be injected into the internal combustion engine 2, is irradiated by the UV light source 12 with UV radiation.
- the UV light source 12 may, for example, as shown in this embodiment, be controlled by the control unit 10.
- the water injectors 6 and the UV light source 12 can be controlled by the control unit 10.
- the control unit 10 is configured, for example, to turn on the UV light source 12 for decontaminating the water and the decontaminated water through the water injectors 6 inject.
- the UV light source 12 may be periodically turned on at predetermined intervals.
- the UV light source 12 may be operated continuously to ensure that contamination of the device 1 does not occur.
- the device 1 has only one UV light source 12, it is possible within the scope of the invention to use a plurality of UV light sources, for example in the lines 7, 8, 11 and 13, in the water tank 5 or can be arranged at other suitable locations. This can ensure that the water to be injected is decontaminated at all times. This causes a fail-safe function of the internal combustion engine. 2
