Abstract
This invention relates to an intake means for a reciprocating internal combustion having a plurality of cylinders having cylinder heads in each of which there are provided at least two charging ducts (14, 15), provided with inlet valves, for intake air for the respective cylinder, of which charging ducts at least one is designed as a swirl duct, one of the charging ducts (14, 15) being controllable via a throttle valve (18) at an associated intake passage (4, 3). In order to achieve a simple design along with a favorable configuration of the valves in terms of space, the intake passages (3, 4) and the charging ducts (14, 15) are incorporated in a cast intake manifold (1) with the intake passages (3, 4) and the charging ducts (14, 15), cylinder by cylinder, being separated from another by means of partitions (2, 16), and a control valve (18) for one intake passage (4) being positioned next to an uncontrolled intake passage (3) at the inlet end to the intake manifold (1).
