A continuous-variable induction system is provided to improve engine output over the entire speed range of an engine, by continuously varying the length of an intake manifold through the position control of a variable intake port. A continuous-variable induction system comprises a variable intake housing(1), a return unit(7), a belt driving unit(9), and a variable intake control belt(5). The variable intake housing has one side connected to a surge tank and the other side connected to each intake port of an engine, and an inner bottom surface on which a partition for division of intake ports is formed. The return unit is arranged in one inner side of the variable intake housing. The belt driving unit is arranged in the other side of the variable intake housing in the width-wise direction, and operates in accordance with a control signal of a controller. The variable intake control belt divides the inside of the variable intake housing into an upper section and a lower section, and has variable intake ports(13) formed on one side at regular intervals in a width-wise direction correspondingly to the intake ports of the engine. One end of the variable intake control belt is connected to the return unit and the other end is connected to the belt driving unit.
