Abstract
A fuel injection system for internal combustion engines includes a fuel injector that includes a spray-orifice plate through which fuel is injected into a combustion chamber. The combustion chamber is bounded by a cylinder wall. A piston is guided in the cylinder wall, and a spark plug projects into the combustion chamber. The diameters of injection orifices positioned on the spray-orifice disk are distributed such that, at a particular point of injection, the injected fuel is distributed as homogenously as possible in an injection volume of the combustion chamber, bounded by the piston and the cylinder wall.
Claims9
A fuel injection system for an internal combustion engine, comprising:
- a combustion chamber that is bounded by a cylinder wall;
- a piston that is guided in the cylinder wall;
- a fuel injector including a spray-orifice disk containing a plurality of injection orifices through which a fuel is injected into the combustion chamber, diameters of the plurality of injection orifices being arranged on the spray-orifice disk in such a manner that, at a point of injection, the fuel is distributed homogenously in an injection volume of the combustion chamber bounded by the piston and the cylinder wall, and the plurality of injection orifices being arranged on the spray-orifice disk in a plurality of rows in a raster-type configuration;
- and
- a spark plug that projects into the combustion chamber;
- wherein the fuel injector injects the fuel into the combustion chamber in at least two injection planes that are set apart from one another by an angle.
