Dual Fuel Injector With Hydraulic Lock Seal And Liquid Leak Purge Strategy |
摘要 |
A dual fuel system includes a dual fuel injector that has disposed therein a gaseous nozzle chamber fluidly connected to a gaseous fuel inlet, and a liquid nozzle chamber fluidly connected to the liquid fuel inlet. The dual fuel injector also includes a hydraulic lock seal with an annular volume of liquid fuel surrounding a guide segment of a gas needle valve member for inhibiting migration of gaseous fuel into the liquid fuel. A liquid fuel common rail is fluidly connected to a liquid fuel inlet. A check valve is fluidly positioned between the gaseous fuel common rail and the gaseous nozzle chamber of the dual fuel injector for blocking liquid fuel leaked into a gaseous nozzle chamber through the hydraulic lock seal from entering the gaseous fuel common rail.
