Abstract: The invention relates to an aluminium alloy, and aluminium alloy product consisting at least in part of an aluminium alloy, an ingot formed from an aluminium alloy, and also a method for producing an aluminium alloy. An improved soldering process is achieved by an AlSi aluminium alloy that has the following proportions of alloy components in percentage by weight: 4.5%? Si ??12%, P ?10 ppm, B ?10 ppm, 30 ppm? Ti ?240 ppm,? Fe ??0.8%, Cu ??0.3%, Mn ?0.10%, Mg ??2.0%, Zn ?0.20%, Cr ?0.05%, the remainder being Al and unavoidable impurities, individually at most 0.05% by weight and in total at most 0.15% by weight, wherein the aluminium alloy is free from Si primary particles with a size of more than 10 ?m.

Abstract: A fuel injection device having a fuel pump for each cylinder of an internal combustion engine, which fuel pump has a pump piston that is driven into a stroke motion by the engine and delimits a pump working chamber, which is supplied with fuel from a fuel tank and is connected to a fuel injection valve, which has an injection valve member that controls at least one injection opening and can be moved by the pressure generated in the pump working chamber in an opening direction counter to a closing force. A first electrically controlled control valve controls a connection of the pump working chamber to a discharge chamber, and a second electrically controlled control valve controls the pressure prevailing in a control pressure chamber of the fuel injection valve, which pressure acts on the injection valve member in the closing direction.
