ABSTRACT:
A fuel injection nozzle for supplying fuel to a compression ignition engine includes a valve member slidable within a bore, a seating in the bore and the valve member being shaped to co-operate with the seating. An extension is carried by the valve member and is slidable in a guide bore extending from the seating to the exterior of the nozzle. The extension has an outlet chamber into which opens a first passage through which fuel can flow as soon as the valve member is lifted from the seating and a second passage through which fuel can flow with increasing quantity as the valve member lifts from the seating. The first passage causes swirling of fuel in the chamber and produces a bushy fuel spray and the fuel flowing through the second passage progressively cancels the swirling to produce a penetrative jet of fuel.
