Forced induction system and method of forced induction for an internal combustion engine

Abstract

Various types of forced induction systems are known for various types of internal combustions engines, including turbochargers and superchargers typically used in cars. The present system includes a first compressor 2 configured to produce a first stream of gas 3, an air multiplier 4 arranged to receive the first stream of gas 3 and eject the first stream of gas 3 over a Coandă surface, the air multiplier 4 configured to entrain ambient air 5 with the ejected first stream of gas to produce a second stream of gas 8, and a second compressor 9 arranged to receive the second stream of gas 8, and configured to compress the second stream of gas 8 for supply to an internal combustion engine. In this way, a mass of air being introduced into an internal combustion engine can be increased, by virtue of the air multiplier 4 upstream of the second compressor 9.
