ジンの燃料制御装置。 A feedback control device that controls the air-fuel ratio supplied to the combustion chamber to a predetermined target air-fuel ratio by driving a control valve provided in the fuel control passage of the carburetor based on a signal from an air-fuel ratio detection means that detects the air-fuel ratio. In a fuel control device for an engine equipped with a carburetor, there is provided an acceleration determining means for determining whether or not an acceleration state is occurring, a gear change determining means for determining whether a gear change has been performed, and signals from the acceleration determining means and the gear change determining means. Based on
1. A fuel control device for an engine, comprising: control means for outputting a signal for correcting an air-fuel ratio to a control valve of the carburetor to correct the air-fuel ratio to be richer by a predetermined amount than a target air-fuel ratio for a predetermined period of time.
