Title:
FUEL CARBURETOR OF ENGINE
Document Type and Number:
Japanese Patent JPH06249072
Kind Code:
A
Abstract:

PURPOSE: To prevent air fuel ratio from variation along with a change in the rotational speed of an engine.

CONSTITUTION: A fuel feed pipe 12 is connected to a proximal end of a main nozzle 5 through a fuel flow controlling valve 11. This flow controlling valve 11 is composed of a fuel feed controller 13 to operatively control the flow. The fuel feed controller 13 calculates a fuel feed Q next after a fuel feed calculating device first indexes the magnitude of a load Tr from a rotational speed signal No of a rotational speed sensor 14 of an engine and a intake negative pressure signal Pb of an intake negative pressure sensor 16 in an intake path 15 so that an actuator 18 for controlling flow of the flow controlling valve 11 is constituted to be adjustably operated. Then, air fuel ratio is kept constant even if the rotational speed of the engine is changed under every load.
