Abstract (en)

[origin: US2008022980A1] The invention relates to a reciprocating internal combustion engine having at least one cylinder ( 1 a) provided with at least one admission valve ( 2 ) and at least one exhaust valve ( 3 ). The pulsating stream of first gas is exhausted from the cylinder ( 1 a) via an exhaust duct ( 5 ) fitted with an expansion nozzle leading tangentially to a peripheral wall of a circularly symmetrical centrifuge chamber ( 10 ) and perpendicularly to the axis of said chamber. The centrifuge chamber ( 10 ) communicates with a duct for feeding the turbines of a turbocharger unit ( 30 ) via an annular radial diffuser.
