- the second filter element is designed to filter off particles or solids which are smaller in size than the particles which can be deposited by the first filter element.
- the first filter element and the second filter element can be changed independently or adapted to the respective requirements.
- the first filter element is arranged in the direction from the outlet to the water tank in front of the second filter element.
- an overflow line is furthermore preferably provided, wherein in the case of a sealed supply line, water flows into the
- the overflow line is preferably arranged on the supply line. Thus, excess water can be passed directly from the supply line to the overflow line.
- the overflow line is arranged in the direction from the outlet or from the supply line to the water tank in front of the filter arrangement.
- excess water can be removed directly from the supply line before filtering the water.
- the filter assembly can withstand a longer life or be used for a longer time to clean it.
- the present invention further relates to an internal combustion engine comprising a water injection device described above, and an injection space in which the water injector of the water injection device is arranged to inject water.
- a further aspect of the present invention relates to a vehicle which comprises a water injection device according to the preceding description and a body with at least one outlet, which communicates via the supply line with the water tank of the water injection device.
- the present invention relates to a method for providing water for water injection by means of a water injection device of an internal combustion engine of a vehicle, comprising at least one water injector for injecting water, a water tank, and a conveying element for conveying water from the water tank to the water injector.
- the method comprises the steps of connecting the water tank by means of a supply line to a drain of a body of the vehicle, in which water passes from the environment, and providing a filter assembly for filtering the water in the supply line before supplying the water into the water tank.
- Figure 1 is a greatly simplified schematic view of a
- Figure 2 is a simplified schematic view of
- Embodiment wherein water from a drain of a vehicle, in which the water injection device is used, a water tank of the water injection device is supplied, and
- FIG 3 is a greatly simplified schematic view of the vehicle in which the water injection device of Figure 2 is provided.
- Water injection device 1 of an internal combustion engine 50 according to a preferred embodiment described in detail.
- the internal combustion engine 50 is operated according to the Otto principle and with gasoline direct injection.
- FIG. 1 shows the internal combustion engine 50, which has a plurality of cylinders, as well as a part of the water injection device 1 according to the invention shown schematically.
- the internal combustion engine 50 comprises per cylinder a combustion chamber 52 in which a piston 53 is movable back and forth. Furthermore, the internal combustion engine 50 preferably has one injection chamber 51 per cylinder, into which water is injected.
- the injection space 51 is preferably designed as an inlet channel. Air is supplied to the combustion chamber 52 via the inlet channel. Exhaust gas is removed via an exhaust passage 54.
- an inlet valve 55 and the exhaust duct 54, an outlet valve 56 are arranged at the inlet channel.
- Reference numeral 57 also denotes a fuel injection valve.
- a water injector 2 is arranged on the injection chamber 51, which injects water into the injection chamber 51 of the internal combustion engine 50 via a control unit 10.

- the overflow line 9 is arranged on the supply line 5 in the direction of the outlet 102 to the water tank 3 in front of the filter assembly 6.
- the Matterlau horrettivo 9 serves to release excess water, which can not be used either because of a clogged filter assembly 6 and / or a full water tank 3, in the environment.
- the water can be released directly via the circulation line 9 in the environment.
- the water injection device 1 can also be operated in combination with other water sources. So it is also conceivable that condensate from an air conditioner of the vehicle via an air conditioning line directly to the water tank 3 or the supply line 5 can be fed.
