ABSTRACT:
Engineers have come to learn that a fuel injection system with a variety of capabilities to produce a variety of injection strategies can better perform and reduce emissions at all engine operation conditions than a fuel injection system limited in its control over injection timing, number, quantity and rate shapes. According to the present invention, in order to increase the variability of available injection strategies, a fuel injection system includes at least one fuel injector fluidly connectable to at least a first common rail and a second common rail. By fluidly connecting the fuel injector to the first common rail, fuel can be injected at a first pressure. By fluidly connecting the fuel injector to the second common rail, fuel can be injected at a second pressure that is independent of the first pressure.
