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.
