Embodiment Construction

[0029] Refer to the attached figure 1 with 2 The device 1 for spraying water of an internal combustion engine 2 according to a first embodiment will be described in detail. In particular, internal combustion engine 2 is operated according to the Otto principle and with direct gasoline injection.

[0030] exist figure 1 An internal combustion engine 2 with a plurality of cylinders is schematically shown in . The internal combustion engine 2 comprises a combustion chamber 20 per cylinder, in which a piston 21 can move back and forth. Furthermore, internal combustion engine 2 preferably includes one inlet duct 22 per cylinder, through which air is conveyed to combustion chamber 20 . The exhaust gas is carried away through the exhaust gas channel 23 . For this purpose, an inlet valve 25 is arranged on the inlet channel 22 and an outlet valve 26 is arranged on the exhaust gas channel 23 . Reference numeral 24 also designates a fuel injection valve.

Abstract

The present invention relates to a device for injecting water of an internal combustion engine (2), comprising a water tank (5) for storing water, at least one water injector (6) for injecting water,which water injector is connected to the water tank (5), at least one UV lamp (12) which is configured to emit ultra violet radiation, and a control unit (10) which is configured to switch on the UV lamp (12) for decontaminating water and injecting the decontaminated water. The invention further relates to an internal combustion engine which comprises a device according to the invention. A furtheraspect of the invention relates to a method for injecting water.

Description

technical field [0001] The invention relates to a device for injecting water into an internal combustion engine and to such an internal combustion engine. A further aspect of the invention relates to a method for spraying water with a water spray device according to the invention. Background technique [0002] Due to the ever-increasing demands on reducing carbon dioxide emissions, internal combustion engines are increasingly being optimized with regard to fuel consumption. However, at operating points with high loads, known internal combustion engines may not be operated optimally with regard to consumption, since the operation is limited due to the tendency to knock and high exhaust gas temperatures. A possible measure for reducing the tendency to knock and for lowering the exhaust gas temperature is water spraying. Here, there is usually a separate water spray system in order to be able to spray water. Thus, for example, WO 2014 / 080266 A1 discloses a water injection sy...
