摘要： A variable pressure fuel injection system and multi-flow rate injector is provided which produces multiple fuel injection flow rates from a common source of pressurized fuel to enable reductions in emissions, combustion noise and particulates while improving fuel consumption. The present invention includes inner and outer needle valve elements biased into respective closed positions against respective valve seats for controlling the flow through corresponding sets of injection orifices. The movement of each valve is controlled by an injection control valve controlling the drain flow of control fuel from respective control volumes positioned at outer ends of the valve elements. Valve element bias spring preloads along with control flow orifices and needle valve element surface areas are selected to cause, for example, single valve operation at low fuel supply pressure and dual valve operation at high supply pressure.

摘要： An improved fuel injection system is provided which incorporates a common rail and a plurality of unit injectors which function together to efficiently produce various injection rate shapes and different combinations of discreet and blended pilot, main, post and after treatment fuel injection events during a single injection. The fuel injection system effectively permits flexible, responsively timed, square shaped, discreet low to mid pressure level injections utilizing the fuel pressure of the common rail while also allowing the unit injector portion to function independently to produce flexible and responsively timed and pressure controlled, triangular shaped high pressure fuel injection events and to recover excess energy. In one embodiment, a separate common rail pump is avoided by utilizing the unit injector plunger to replace fuel into the common rail which was previously injected.
