First Claim
Patent Images
1. A fuel control system for an internal combustion engine including an air intake passage, a throttle valve disposed therein and means for injecting fuel into said intake passage, comprising:
- means for detecting the amount of depression by a vehicle occupant of an accelerator pedal;
means for determining the amount of fuel to be injected in response to the detected amount of acceleration and correspondingly operating said fuel injecting means; and
means for determining the amount of air to be inducted in response to the determined amount of fuel anc correspondingly operating said throttle valve so that air and fuel are mixed in a predetermined ratio.

Abstract
A fuel control system for internal combustion engines includes a fuel injection control unit responsive to the amount of depression of an accelerator pedal to determine the fuel quantity and an air intake control unit which determines the amount of air to be mixed therewith in response to the determined fuel quantity to correspondingly operate a throttle valve. Fuel and air are supplied to the engine such that they reach the cylinder simultaneously.

7. A fuel control system for an internal combustion engine including an air intake passage, a throttle valve disposed therein and means for injecting fuel into said intake passage, comprising:
-
means for detecting the amount of depression by a vehicle occupant of an accelerator pedal; means for determining the amount of fuel to be injected for each revolution of the engine in response to the detected amount of acceleration and correspondingly operating said fuel injecting means; means for detecting the speed of said engine; and means for determining the amount of air to be inducted for each revolution of the engine in response to the determined amount of fuel and to said detected engine speed such that air and fuel are mixed in a predetermined ratio and correspondingly operating said throttle valve.
