Disclosed is an injector nozzle through which fluid is delivered and which has a port () having an internal surface and a valve member () having a complementary external surface. The valve member () is movable relative to the port () to respectively provide a passage between the internal and external surfaces for delivery of fluid in the form of a spray. Alternatively, sealed contact of the surfaces will prevent the delivery of fluid. The nozzle includes a flow control body () located beyond an extremity of the port (). The flow control body () has a control surface () arranged downstream of the port () in the direction of movement of the valve member (). The control surface () is configured and positioned to promote the fluid spray established by the fluid issuing from the port () to in part follow a path determined by the shape of the control surface (). The flow control body () includes an insulating region () arranged to restrict heat transfer from the control surface () to the nozzle. The insulating region () may be the spacing between the surface () of the flow control body () closest to an end face () of the valve member () and that end face ().

Fuel injector nozzles

A method of lubricating and cleaning a fuel injector of a fuel injection system of an internal combustion engine during running of the engine including delivering both a lubricant and a cleaning additive to the injector. The injector injects directly into the combustion chamber of the engine. The lubricant and cleaning additive are delivered to the fuel exit area of the injector.
