Abstract
In an internal combustion engine with direct fuel injection, which comprises a number of operating elements each including a combustion chamber delineated by an internal wall of a cylinderhead and a piston movably disposed in a cylinder, an injector mounted in the cylinderhead has a fuel injection nozzle which injects fuel into the combustion chamber in a cone-like pattern wherein an ignitable fuel/air mixture is formed and a spark plug is mounted on the cylinderhead within a spark plug sleeve which extends into the combustion chamber and forms, adjacent the spark plug electrodes, an ignition chamber which is in communication with the interior of the cone-like fuel spray pattern so as to receive therefrom an easily ignitable relatively rich fuel mixture which, upon ignition by the spark plug, generates a flame beam igniting the fuel mixture within the cone-like spray pattern.
