    摘要： A fuel injector for the direct injection of fuel into the combustion chamber of a mixture-compressing internal combustion engine having external ignition includes a valve housing formed by a nozzle body, and a seal which seals the fuel injector from a cylinder head of the internal combustion engine. The seal has a sleeve-type design with a structured cross section and extends across the axial length of the nozzle body.

    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.

    摘要： In a method for forming the mixture in a combustion space of an internal combustion engine, fuel is injected into the combustion space with a varying fuel mass flow during an operational cycle of the internal combustion engine. In one embodiment at least under certain engine operating conditions, three-stage fuel injection is carried out during the compression phase so that a main fuel quantity is injected in a first injection step, an additional fuel quantity with a reduced fuel mass flow is injected in a second injection step and an ignition fuel quantity is injected in a third injection step. In another embodiment, a fuel quantity is injected with a fuel mass flow which is reduced so that it falls steadily from a maximum initial value down to zero and, in accordance with a third method, a fuel quantity is injected during the induction phase with a fuel mass flow which is, at least at times, proportional to the air mass flow.
