Document Type and Number:
Japanese Patent JP2654029
Kind Code:
B2
Abstract:
Improvements in fuel injection nozzles for spark ignited internal combustion engines enabling a metered quantity of fuel entrained in a gas to be delivered into a combustion chamber to optimize the efficiency of operation of the engine. The fuel injection nozzle has a port (11) and a valve (15) movable relative to the port (11). Port (11) and the valve (15) have respective annular sealing faces (13) and (18) defining an annular frustoconical shaped throat (25) when the nozzle is open for the flow of metered fuel therethrough. The nozzle has a shroud (20) extending from the port (11) surrounding the periphery of the valve (15) when the nozzle is open and defining a delivery passage 27 downstream of the throat in the direction of fuel flow towards the combustion chamber. The delivery passage 27 is configured to be purged of fuel after each fuel delivery cycle to prevent carbon build-up in the nozzle.
