A variable air induction control system is described for a multi-cylindered internal combustion engine, comprising: a first means disposed in the vicinity of the cylinders of the engine for respectively detecting a combustion state therein; a second means for receiving an output signal of the first means and for generating a signal indicative of a pressure in the cylinders; a third means disposed in a rotational shaft of the engine for detecting an angular position of a crankshaft to generate a signal indicative of the engine speed; a first air intake passage provided upstream of a throttle valve for introducing an air into the chambers; a second air intake passage connected to the first air intake passage at one end and at the other end thereof to the cylinders, the second air intake passage having a variable diameter and length; control means for receiving the output signals from the second and third means, and for outputting a setting signal to set the diameter and length of the second air intake passage such that the cylinder pressure is constantly maximized; and an actuator means receiving the setting signal from the control means for adjusting the second air intake passage to have diameter and length in accordance with the setting signal.
