摘要： In a direct injection internal combustion engine with a combustion chamber which is delimited in each cylinder by a longitudinally movable piston and by the inner wall of a cylinder head, an injector injects fuel into the combustion chamber in order to form an ignitable fuel/air mixture with combustion air that is supplied separately, the mixture being ignited by a spark plug. The fuel is injected in a conical shape and the electrodes are protected from being wetted by fuel and from coking if they are located outside the lateral surface of the cone of fuel produced by the injection nozzle. In order to bring an ignitable mixture between the electrodes and to ensure an optimal operating performance of the internal combustion engine by improving the combustion process, the combustion chamber is configured so that the cone of fuel is injected in a free jet that is substantially unaffected by the perimeter of the combustion chamber, and the electrodes of the spark plug project inside a fuel vortex which emerges from the lateral surface during injection.

摘要： In internal combustion engines with direct fuel injection an injector injects fuel into the combustion chamber to form an ignitable fuel/air mixture with separately supplied combustion air, with the mixture to be ignited by a spark plug. The fuel is injected in a cone shape and the electrodes are protected from being wetted with fuel and coking if they are disposed outside the lateral surface of the conical fuel jet generated by the injection nozzle. In order to bring ignitable mixture between the electrodes and to ensure optimal operating behavior of the internal combustion engine by improving the combustion sequence, a combustion chamber configuration is provided such that the conical fuel jet is injected in a free jet which is substantially uninfluenced by the combustion chamber perimeter, and the electrodes of the spark plug project into a fuel vortex extending from the lateral surface during injection.

摘要： Direct-injected, four-cycle internal combustion engines can be operated advantageously with charge stratification, with the fuel being injected into the combustion chamber during the compression stroke of the piston in the cylinder as a conical fuel stream. To ignite the stratified mixture cloud, an igniting spark jumps between the electrodes of a spark plug and thus contacts an ignitable mixture. In order to guarantee sufficient preparation and stable ignition and combustion of the fuel/air mixture in the long term, it is proposed that the electrodes be located outside a conical jacket of the fuel stream and that the combustion chamber roof be so designed that the conical jacket is formed during injection between the injector and the spark plug close to the wall of the combustion chamber roof. The mixture guided in the conical jacket is deflected outward in the direction of the electrodes as a result.
