A system of an internal combustion engine which is induced by an air flow amplifier via a turbine and centrifugal compressor, one side of which is mechanically and pneumatically connected to the turbine and the other side with an air intake of the internal combustion engine. The operation of the engine induction system can be enhanced by using an intercooler that supplies a cooled primary flow of compressed air to the air amplifier. The use of the engine induction system without a turbocharger and, hence, without hot exhaust gases, makes it possible to utilize light magnesium alloys for parts of the turbine and compressor and thus to reduce the weight of the system as a whole.
