Abstract

PURPOSE: To provide an intake structure for an internal combustion engine, which can form swirl in the low speed operation and smoothly withdraw a geat quantity of intake air in a state free from swirl in the high speed, thus permitting improvement of the combustion efficiency of the whole engine.
CONSTITUTION: A high speed side intake port 8 and a lower stage low speed side intake port 8 and a lower stage low speed side intake part 10 are formed integral with each other for communication from one side of a cylinder head 5 to an intake valve 7 on the other side, and a planer inlet control valve 14 is pivotably mounted on a pin 13 at an end of an intake air distribution cylinder 12. The valve 14 is operated from a control section 19 through rack 15 and gear 16 in accordance with the extent of advancement or retreat of a control rack 18 provided on a fuel injection chamber 4 in a state free swirl a at the time of the high speed operation and to the side of a port 10 from and thence into a combustion chamber 4 by causing the formation of a swirl at the time of the low speed.
