Title:
DEVICE FOR SUPPLYING FUEL
Document Type and Number:
Japanese Patent JPS54160938
Kind Code:
A
Abstract:

PURPOSE: To prevent a device for supplying fuel for an internal combustion engine from decreasing its atomizing capacity even when the fuel flow rate of the device is increased by incorporating the atomizing capacity at the fuel injection nozzle itself.

CONSTITUTION: There is provided an air injection nozzle 15 communicating with a conduit 11 around a fuel supply nozzle 14. There is also provided an orifice 17 surrounding the jet port 16 of the fuel supply nozzle 14 at the end of the respective nozzles 14, 15. Air is supplied from the upstream side of an air measuring valve at a flowrate measuring device 9, and injected from the orifice 17 toward the port 16 of the nozzle 14 due to the differential pressure (p1 - P2) between the upstream and the downstream of the air measuring valve. Fuel is fed from a fuel measuring mechanism 12 through a fuel supply tube 18, and injected from the port 16 of the nozzle 14 toward the throttle valve 7. The nozzle 14 is a swirl nozzle. The fuel is injected from a port 20 tangentially toward a turbulence chamber 19.
