Fuel control system for modifying fuel injection according to transmission type and acceleration

Claim 1

A fuel control system for an automotive engine, comprising: fuel injection means for injecting a properly controlled quantitiy of fuel into cylinders of said automotive engine ; engine control value detection means for detecting an engine control value which varies with a speed of rotation of said automotive engine; a temperature sensor for detecting a temperature of said automotive engine; and a control unit for (a) determining if said temperature is lower than a preselected temperature, (b) determining whether said engine control value is at least equal to a specific value, (c) calculating, when said engine control value is at least enqual to said specific value, a current amount of fuel according to said engine control value, and using, as said properly controlled quantity of fuel, said current amount of fuel when said current amount of fuel is equal to or larger than a previously calculated amount of fuel and said previously calculated amount of fuel when said current amount of fuel is smaller than said prevously calculated amount of fuel, (d) causing said fuel injection means to inject the properly controlled quantity of fuel into said cylinders when said temperature is not lower than said preslected temperature and said engine control value detection means detects that said engine control value is at least equal to said specific value, and (e) decreasing said specific value as said temperature sensor detects lower temperatures.
