    • A fuel injection control system and method for delivering multiple fuel injections to a cylinder of an engine during a fuel injection event based upon engine operating conditions, the control system including an electronic controller coupled to an electronically controlled fuel injector, and a plurality of sensors coupled to the controller for inputting certain signals representative of certain engine operating conditions of the engine, the controller being operable to output a fuel injection signal to the fuel injector to deliver a first, a second, and a third fuel shot to the cylinder during a fuel injection event based upon the sensor signals. The controller also delivers each of the multiple fuel injection shots within defined cylinder piston displacement parameters during a particular piston stroke, within defined fuel apportionment limits, and within defined delay limits between each respective fuel shot so as to control exhaust emissions.
    • 一种燃料喷射控制系统和方法,用于在燃料喷射事件期间基于发动机操作条件向发动机的气缸输送多个燃料喷射,所述控制系统包括耦合到电子控制的燃料喷射器的电子控制器和耦合到多个传感器 控制器用于输入表示发动机的某些发动机工作条件的某些信号,所述控制器可操作地将燃料喷射信号输出到燃料喷射器,以在燃料期间将第一,第二和第三燃料喷射到气缸中 基于传感器信号的注入事件。 控制器还在特定的活塞冲程内,在确定的燃料分配限度内,并且在每个相应的燃料喷射之间的限定的延迟限度内,将定义的气缸活塞位移参数内的多个燃料喷射射击中的每一个传送到控制废气排放。
