Title:
AIR-FUEL MIXTURE RATIO CORRECTING DEVICE FOR CARBURETOR OF ENGINE
Document Type and Number:
Japanese Patent JPH06241122
Kind Code:
A
Abstract:

PURPOSE: To obtain a proper air-fuel mixture ratio in the all load range of an engine so as to suppress wasteful consumption of fuel and generation of smoke.

CONSTITUTION: In an air-fuel mixture ratio correcting device 20 attached to an already installed carburetor, a load detecting means 25 for outputting a load signal J1 by detecting the load of an engine, an air-fuel ratio detecting means 26 for outputting an air fuel ratio signal J2 by detecting the air-fuel mixture ratio of the engine, and a correction control circuit 23 for outputting an air-fuel ratio correcting signal K on the basis of the load signal J1 and the air-fuel ratio signal J2 are provided, and a setting apparatus operating means 22 can be driven and controlled on the basis of the air-fuel ratio correcting signal K from the correction control circuit 23. The fuel flow rate of a main jet 12 is regulated in response to the load by regulating and driving a flow rate setting apparatus 21 by the setting apparatus operating means 22.
