Abstract
The acceleration of an internal combustion engine is detected for generating at least one electrical signal indicating when acceleration exceeds a predetermined degree. In response to this signal, the fuel feeding rate of the engine is instantly increased by a predetermined increment. After each increasing operation is executed, the increased fuel feeding rate is decreased with a variable reduction rate. The variable reduction rate, according to the present invention, is decreased in accordance with the lapse of time after the increasing operation has been executed.
Claims12
A method of controlling the fuel feeding rate of an internal combustion engine, comprising the steps of:
- generating at least one first electrical signal when acceleration of said engine exceeds a predetermined degree;
- instantly increasing the fuel feeding rate of the engine by a predetermined increment in response to said first electrical signal;
- and
- after each execution of said increasing step, decreasing the increased fuel feeding rate with a variable reduction rate which reduction rate decreases in accordance with the lapse of time after said increasing step has been executed.
An apparatus for controlling the fuel feeding rate of an internal combustion engine, comprising:
- means for generating at least one first electrical signal when acceleration of said engine exceeds a predetermined degree;
- means for substantially instantly increasing the fuel feeding rate of said engine by a predetermined increment in response to said first electrical signal;
- and
- means for decreasing, after each of said fuel feeding rate increases, said fuel feeding rate by a variable reduction rate, said variable reduction rate decreasing with time measured from said fuel feeding rate increases.
