ABSTRACT:
An air intake arrangement for an internal combustion engine comprising: a main air intake conduit leading to a gas intake valve (241 ) for respective engine cylinders (206 ) and including a main air intake passage (202 ), a main collector chamber (204 ) and independent branching air intake passages (205) for the respective engine cylinders (206) connected in series; a throttle valve (203 ) disposed in the main intake air passage (202 ) for controlling the flow rate of air passing therethrough; an auxiliary air intake passage (210 ) bypassing the main air intake conduit, an inlet port of the auxiliary air intake passage (210 ) opens into the main air intake passage (202) at the upstream of the throttle valve (203 ), an outlet port (213 ) of the auxiliary air intake passage (210 ) opens into the respective independent branching air intake passages (205) near the gas intake valve (241) for the respective engine cylinders (206 ) in such a manner that gas blown-out from the auxiliary air intake passage (210 ) induces a gas swirl in the respective engine cylinders (206); an intake air control valve (211) disposed in the auxiliary air intake passage (210 ) for controlling the flow rate of air passing therethrough; and a control unit (222) which determined an operating condition of the internal combustion engine and controls an opening degree of the intake air control valve (211) based on the determined engine operating condition.
