Abstract

An internal combustion engine in-cylinder fuel injector nozzle having a body having a fuel passage terminating in a port that, in use, communicates the fuel passage with an engine combustion chamber. The port has an annular seat therein and a valve element also having an annular seat co-operates with the seat in the port to control fuel flow therethrough. An annular flow directing surface extends downstream from each of the annular seats, and each flow directing surface is contoured to blend smoothly with its respective seat.
