Abstract
A fuel injection system for internal combustion engines has at least one fuel injector which injects fuel into a combustion chamber with a spark plug projecting into the combustion chamber. The fuel injector has a valve body which has a plurality of injection holes situated on the circumference. The injection holes are designed so that a conical spray jet is produced in the combustion chamber. At least the injection holes situated directly on both sides of the spark plug have an elongated cross section.

A fuel injection system for an internal combustion engine, comprising:
- a combustion chamber;
- a spark plug projecting into the combustion chamber;
- and
- at least one fuel injector for injecting a fuel into the combustion chamber, wherein:
- the at least one fuel injector includes a valve body having a plurality of injection holes situated on a circumference so that an at least approximately conical injection jet is produced in the combustion chamber, and
- at least those of the plurality of injection holes situated directly on both sides of the spark plug have an elongated cross-section.
