  • Method of and apparatus for controlling the air intake of an internal combustion engine
    Patent number: 4386591
    Abstract: The sectional area of an air bypass passage which is bypassing a throttle valve in an intake passage of an internal combustion engine is increased or decreased depending upon the difference between the actual rotational speed of the engine and the variable desired rotational speed. The variable desired rotational speed is slowly changed with respect to time according to an increment rate or to a decrement rate, when the operating condition of the engine and/or the load condition of the engine changes.
