Abstract

A fuel injection system for internal combustion engines has at least one fuel injector which injects fuel into a combustion chamber delimited by a cylinder wall in which a piston is guided, and it has a spark plug which protrudes into the combustion space, and the fuel injector is designed so that a conical spray jet is produced in the combustion chamber. The conical spray jet has an angle cutout in the area of the spark plug.
