Abstract (en)

[origin: CA2473639A1] A fuel injection valve is provided for introducing a fuel into an engine a nd controlling fuel flow to reduce variability between injection events. The fuel injection valve employs an arrangement for a valve nozzle that cooperates with a valve needle to provide a range of needle movement within which the fuel mass flow rate is substantially constant. This can be achieved by providing a restriction with a constant flow area for a predetermined range of needle movement. The method comprises commanding a valve needle to a position within the predetermined range of needle movement to reduce variability in the fuel mass flow rate, particular ly when the engine is idling or operating under low load conditions.
