Patent ID: 6883491

Claim:
A fuel-injection system for an internal combustion engine, comprising: at least one fuel injector for injecting a fuel into a combustion chamber that is delimited by a cylinder wall in which a piston is guided; a spark plug projecting into the combustion chamber, the at least one fuel injector being located in the combustion chamber in a region of a gas-intake valve toward the cylinder wall and producing a plurality of fuel jets, wherein: at least one of the plurality of fuel jets has a tangential orientation into a region of the spark plug, spray-discharge orifices of the at least one fuel injector are distributed in such a manner that at least two of the plurality of fuel jets are injected at a predefined opening angle into the combustion chamber, tangentially to the spark plug, the spark plug is located on a bisectrix of the predefined opening angle, the predefined opening angle, as a function of a clearance of the at least one fuel injector to the spark plug, is dimensioned such that an ignitable mixture is produced on both sides tangentially to an ignition electrode of the spark plug, at a piston position near top dead center, at least some of the plurality of fuel jets are evenly aligned with the combustion chamber, and the plurality of fuel jets are oriented in three planes at an angle γ 1 between a first plane and a second plane, and at an angle γ 2 between the second plane and a third plane, the first plane, which is closest to a cylinder head, is formed by two of the plurality of fuel jets that are tangentially aligned to the spark plug.
