ABSTRACT:
An internal combustion engine with an air intake system for transmitting combustion air to at least one cylinder chamber is involved which consists of one or more intake pipes (1-4) coiled more than 180.degree. and of means for controlled variation of the effective intake pipe length as well as at least one throttle mechanism whose movement can be controlled, where the means for varying the intake pipe length and the throttle mechanism for controlling the air volume are combined structurally in a substantially cylindrical, rotary slide valve (17) which can be rotated in a controlled manner about a cylinder axis (18) and also in a controlled manner can be moved to a limited degree in the direction of the cylinder axis (18).
