ABSTRACT:
High pressure post injection using only one valve is accomplished by fluidly connecting the control valve (76) in a fuel injection pump system (50) to the upper nozzle chamber (70) of a fuel injector (60), and connecting the upper nozzle to a reservoir (80) by way of a restriction. The restriction creates enough residual pressure in the fuel circuit to enable high pressure post injection by closing the control valve (76) a second time.
