Abstract
High pressure post injection using only one valve is accomplished by fluidly connecting the control valve () in a fuel injection pump system () to the upper nozzle chamber () of a fuel injector (), and connecting the upper nozzle to a reservoir () 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 () a second time.
