    Abstract: A two-stroke internal combustion engine, comprising a cylinder, a piston reciprocating within the cylinder, a crankcase that is correspondingly pressurised and de-pressurised beneath said piston, a throttle-controlled carburettor for creating combustible air- fuel mixture, a passageway for conducting air-fuel mixture into periodically de-pressurised crankcase, scavenging passageways conducting the air-fuel mixture from the crankcase and into the cylinder once the piston has opened said cylinder's exhaust and scavenging ports, a conduit delivering pressurised-air from the means of its pressurisation and into the cylinder via its own passageway and its own port, a pressurised-air passageway with a port residing between at least two ports through which air-fuel mixture emerges from its passageways for the purpose of jointly scavenging the cylinder's exhaust once the piston has opened their respective ports.

    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 Coanda 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 upstream of the second compressor.

    Abstract: A Venturi device with a primary flow path and a secondary flow path introduced into the primary flow path, wherein a flow of one or more flowable mediums in the primary flow path and the secondary flow path creates a vortex generating a suction at an inlet of the Venturi device. Systems incorporating the Venturi device in which the primary flow path is charged with energy in the form of thermal energy from the ambient environment through the flow-induced vortex formation. Supercharger systems incorporating the Venturi device, wherein the primary flow of air into an engine is compressed with exhaust gases recirculated through the secondary flow path.
