Apparatus for controlling the supply of fuel to an internal combustion engine
First Claim
1. In an apparatus for controlling the supply of fuel to an internal combustion engine having a control valve means for controlling the amount of air to be supplied to an engine piston downstream of a throttle valve, the improvement which comprises:
- means for detecting any disorder in the amount of air and outputting a disorder indicating signal;
an engine speed sensor for detecting the rotating speed of the engine;
a throttle opening sensor for detecting the degree of opening of said throttle valve; and
fuel cut means coupled to said disorder detecting means, said engine speed sensor, and said throttle opening sensor, for determining a fuel cut area defined by the degree of throttle opening and the rotating speed of the engine, and for executing fuel cut in response to the disorder indicating signal, when the output of said engine speed sensor and said throttle opening sensor indicate that the engine is operating within the fuel cut area.

Abstract
An apparatus is provided for controlling the supply of fuel to internal combustion engine having a control valve for controlling the amount of air to be supplied to an engine piston downstream of a throttle valve. The apparatus comprises a detector for detecting any disorder in the amount of air and for providing a disorder indicating signal. An engine speed sensor detects the rotating speed of the engine and a throttle opening sensor detects the degree of opening of the throttle valve. A fuel cut circuit is coupled to the disorder detector, the engine speed sensor, and the throttle opening sensor for storing a fuel cut area defined by the degree of throttle opening and the rotating speed of the engine. The fuel cut circuit produces, in response to the disorder indicating signal, a fuel cut command signal when the outputs of the engine speed sensor and the throttle opening sensor indicate that the engine is operating within the fuel cut area.
