    摘要: A method for determining an air mass in an air separator of a water direct injection system for injecting a water/fuel mixture into a combustion chamber of an engine of a motor vehicle. The air separator is disposed between a water pump for delivering water of the water/fuel mixture and a high-pressure pump for feeding the water/fuel mixture to a high-pressure injector for injecting the water/fuel mixture into the combustion chamber. The method includes increasing a pressure of the water from a first pressure value to a second pressure value by the water pump, determining a water volume delivered by the water pump during the increasing of the pressure of the water by the water pump, and determining the air mass in the air separator on a basis of the determined water volume delivered by the water pump.

    摘要: A tank arrangement includes a tank container which encloses a tank space where the tank container has a bottom side and a top side which is disposed opposite from the bottom side. A swirl pot is disposed in the tank space and has a swirl pot opening. A suction jet pump has a nozzle, a propulsion jet line, and a suction jet line where the propulsion jet line and the suction jet line open into the nozzle and where the nozzle has an outlet opening. The nozzle is disposed on the top side of the tank container at a distance above the swirl pot opening with the outlet opening directed toward the swirl pot opening.
