Abstract (en)
[origin: WO2016177544A1] Method for operating a device (1) for injecting water into an internal combustion engine, wherein the device (1) has – a water tank (3) for storing water, – a pump (4) for delivering the water, wherein the pump (4) is connected to the water tank (3) via a first line, and wherein the pump (4) can be operated in a delivery mode and in a back-suction mode, – a drive (5) for driving the pump (4), – at least one water injector (6) which is designed for injecting water into an air-conducting line (7) of the internal combustion engine (2), wherein the water injector (6) is connected to the pump (4) via a second line (11), wherein, during the operation of the pump (4) in the back-suction mode, in which the water is delivered in the direction of the water tank (3), the at least one water injector (6) is opened such that air flows into the second line (11).
