Abstract
An air intake system for a supercharged automotive engine has an independent air intake passage an end of which is communicated independently and separately with a combustion chamber of each cylinder and a supercharger for supercharging intake air. The air intake valve closing timing is delayed after bottom dead point and the independent air intake passage is shaped so that the number of revolutions which causes maximum inertia in the independent air intake passage by supercharging in a high-speed region is higher than the number of revolutions of the engine at which maximum horse power is generated.
