Electronic control carbureter

Abstract

Abstract PURPOSE: To simplify the structure of electronic control carbureter and further to supply a sufficient fuel-air mixture to the engine even if the electron control failed, by adjusting the opening of an auxiliary valve and a control valve via a control circuit in accordance with the detector signal showing the operational condition. CONSTITUTION: Main air bleeder 7 and variable air bleeder 8 are open to the midway of main fuel path 6 connected to main noxxle 5, which is open to venturi 4. Variable bleeder 8 is provided with control valve 9 and on-off type main fuel correction electromagnetic valve 10. Electromagnetic valve 10 is supplied with main system air-fuel ratio control signal A. Auxiliary fuel path 16, which is linked to auxiliary nozzle 15, is provided with on-off type auxiliary fuel control electromagnetic valve 17. Auxiliary fuel control signal B is supplied to open or close it. Air supply path 18 is provided with on-off type air control electromagnetic valve 19. The valve 19 is supplied with idling rotation and start control signal C. COPYRIGHT: (C)1980,JPO&Japio
