ABSTRACT:
An apparatus for controllably sucking intake air into each cylinder of an internal combustion engine and method for controlling the intake air quantity of the internal combustion engine are disclosed in which, in an intake air passage, a first throttle valve associated with an acceleration element (accelerator pedal) is installed in a portion of the intake air passage located upstream of an intake manifold and a plurality of second throttle valves are installed in intake ports branched from the intake manifold whose opening angle is controlled by means of an actuator in response to a control signal input thereto. In addition, a bypass passage is connected between the intake air passage upstream of the first throttle valve and exits of the intake ports downstream of the second throttle valves to provide a swirl stream of the intake air sucked into each combustion chamber and a bypass intake air quantity control valve is installed in the bypass passage. Furthermore, a plurality of fuel injection valves are intervened in branched bypass passages located adjacent to the intake ports. The engine output control using the apparatus described above provides a faster responsive characteristic.
