Abstract
A fuel injection system for internal combustion engines comprises a fuel injector that injects fuel into a combustion chamber, the combustion chamber being delimited by a cylinder wall in which a piston is guided, and a spark plug that protrudes into combustion chamber. The fuel injector produces a conical mixture cloud in the combustion chamber through at least one row of injection orifices arranged circumferentially on a valve body of the fuel injector. The valve body also provides a centrally arranged injection orifice that produces a central area of the mixture cloud directed towards the spark plug.
