Abstract: A dual fuel injector utilizes first and second control valves to open and close first and second nozzle outlet sets to inject a first fuel and a second fuel, respectively. The first and second control valves have concentric lines of action, and include a self alignment feature with respect to a flat seat. The two fuels may differ in at least one of chemical identity, matter phase and pressure.

Abstract: A fuel injector includes an injector body that defines a fuel inlet, a drain outlet and a nozzle outlet, and has disposed therein a nozzle chamber, a needle control chamber and a valve chamber. The needle control chamber is fluidly connected to the drain outlet through a drain passage that includes the conical seat, is fluidly connected to the nozzle chamber through a Z orifice, and fluidly connected to the valve chamber through an A orifice. The nozzle chamber is fluidly connected to the valve chamber by a pressure passage that includes an F orifice that opens through a flat seat. A control valve member is trapped to move between contact with conical seat and contact with the flat seat. An electrical actuator is operable to push the control valve member away from the conical seat toward the flat seat when energized. A direct control needle valve has an opening hydraulic surface positioned in the nozzle chamber and a closing hydraulic surface positioned in the needle control chamber. The fuel injector may include first and second electronically controlled valves for independently injecting a gaseous fuel and a liquid fuel.

Abstract: A dual fuel common rail system may be operated in a regular mode in which a relatively large charge of gaseous fuel is ignited by compression igniting a relatively small injection quantity of liquid diesel fuel. The dual fuel system may be operated in a single fuel limp home mode in which liquid diesel fuel is injected at higher pressures. Over pressurization of the gaseous fuel side of the fuel system due to leaked liquid fuel is avoided by regularly injecting leaked liquid fuel, but not gaseous fuel, from the gaseous nozzle outlet set during the limp home mode of operation.
Abstract translation: 双燃料共轨系统可以以常规模式操作，其中相对较大量的气体燃料通过压缩点燃，点燃相对较小量的液体柴油燃料。 双燃料系统可以在单一燃料跛行家庭模式中操作，其中液体柴油燃料在较高压力下喷射。 由于泄漏的液体燃料，燃料系统的气体燃料侧的过度加压通过在跛行家庭操作模式期间从设置的气体喷嘴出口定期注入泄漏的液体燃料而不是气体燃料来避免。
