Claim Text:
1. A method of compounding at least one rotary engine, the method comprising: drivingly engaging a second turbine and a compressor in a turbocharger; forming a fluid communication between an outlet of the compressor and an inlet port of each rotary engine; forming a fluid communication between an exhaust port of each rotary engine and an inlet of a first turbine, including directing exhaust pulses from the rotary engine onto blades of a rotor of the first turbine; driving a rotation of the blades of the rotor of the first turbine using kinetic energy imparted by impingement of the exhaust pulses against the blades; forming a fluid communication between an outlet of the first turbine and an inlet of the second turbine of the turbocharger; and drivingly engaging each rotary engine and the first turbine to a common shaft; wherein the first turbine is configured as a velocity turbine and the second turbine is configured as a pressure turbine, the first turbine having a pressure ratio smaller than that of the second turbine.
