The invention relates to an air-inlet system (10), and relates to an air-conditioning system (100, 101) and an internal combustion engine (200) comprising the air-inlet system. The air-inlet system comprises an air intake port (20), an air output port (30) and a turbine (40) for controlling air mass flow into a combustion chamber (202) of an internal combustion engine. The turbine is provided with a propeller hub (42) which comprises at least one blade (44). The propeller hub is arranged between the air intake port and the air output port for propelling the blade of the turbine. The turbine has an air-flow resistance for determining the air mass flow into the combustion chamber. The effect of the air-inlet system according to the invention is that the use of a turbine enables to use at least some of the pressure drop across the turbine to drive the blade of the turbine for generating rotational energy.
