Method and device for filling an injection device for injecting water into an internal combustion engine

摘要

A method and a device for filling an injection system for injecting water into an internal combustion engine are proposed, wherein the injection system has a pump (3), a water rail (1) and injection valves (4). By the pump (3) water from a water tank (5) is pumped into the Wasserrail (1) and injected from the Wasserrail (1) through the injection valves (4) in the internal combustion engine. It is provided that for filling the injection system in a first step, the pump (3) will actuate at least one opened injection valve (4) until a water pressure in the water rail (1) can be detected.
