Abstract
Often there is a limited fuel injector spatial envelope above and within a cylinder head for a fuel injector. In order to fit a fuel injector with a direct control needle valve and a capability of injecting fuel at a rail pressure and an intensified pressure into the limited fuel injector spatial envelope, the present disclosure includes a fuel injection system in which a pressure intensifier and nozzle outlets of a fuel injector are fluidly connected to a source of fuel via an intensifier line and an injector line, respectively. The flow of fuel to the pressure intensifier is controlled via a valve attached to the source of fuel.
