摘要： A fuel injector is provided comprising an outer housing, a nozzle housing disposed within the outer housing, a flow path between the outer housing and the nozzle housing, the flow path being coupled to a low pressure fuel source, and a circumferential gap in flow communication with the flow path and extending about a tip of the fuel injector between an outer surface of the nozzle housing and an inner surface of a combustion shield adjacent the injector tip. The circumferential gap is in flow communication with a drain gap between the outer housing and a bore for receiving the fuel injector, the drain gap routing the low pressure fuel away from the injector tip.

摘要： A fuel pump is disclosed wherein a substantially cylindrical plunger bore is provided with an annular drain groove fluidically coupled to a drain duct. A pump plunger is driven by a drive system located in a separate mechanical compartment that holds a reservoir of lubricating oil. An annular seal is provided adjacent the drain groove substantially at the end of the bore and retained in position by a seal support. Exemplary embodiments provide the drain groove and seal as being positioned immediately adjacent one another so that the seal forms a lower wall of the drain groove.

摘要： A flow limiter for a fuel system is provided. The flow limiter includes a self-contained portion that enables testing of the flow limiter prior to assembly into a fuel system. A housing of the flow limiter is arranged to provide reduced or no pressure differential across a wall of the housing, permitting the housing to be reduced in size and thickness and providing improved consistency of operation.

摘要： The present disclosure provides a fuel injector for an internal combustion engine with a fuel injector body having a valve chamber, a first conduit in fluid communication with the valve chamber for a first flow of fuel having a first pressure, and a second conduit in fluid communication with the valve chamber for a second flow of fuel having a second pressure. The fuel injector further includes a valve member configured to move between the first conduit and the second conduit. Additionally, an actuator of the fuel injector is configured to move the valve member during a fuel injection cycle. The fuel injector is configured to operate in at least three modes.
