Systems and methods are provided for operation of fuel injectors within an applied-ignition, direct-injection internal combustion engine. In one example, a needle of a fuel injector is moved from a retracted position to an extended position relative to a plurality of injection holes of a nozzle of the fuel injector, with at least one injection hole being separated from a fuel supply system earlierthan each other injection hole. In a partially retracted position, fuel flow along a first side of the needle is decreased relative to fuel flow along a second side of the needle. 本发明提供用于在应用点火直喷内燃发动机内操作燃料喷射器的系统和方法。在个示例中，燃料喷射器的针形件相对于燃料喷射器的喷嘴的多个喷射孔从缩回位置移动到延伸位置，其中至少个喷射孔比每个其它喷射孔更早地与燃料供应系统分开。在部分缩回位置中，沿着针形件的第侧的燃料流量相对于沿着针形件的第二侧的燃料流量减少。
