Abstract:
A rotary engine where the rotor cavity has a peripheral inner surface having a peritrochoid configuration defined by a first eccentricity and the rotor has a peripheral outer surface having a peritrochoid inner envelope configuration defined by a second eccentricity larger than the first eccentricity. Also, a rotary engine where the rotor cavity has a peripheral inner surface having a peritrochoid configuration defined by an eccentricity, and a rotor with a peripheral outer surface between adjacent ones of the apex portions being inwardly offset from a peritrochoid inner envelope configuration defined by the eccentricity. The engine may have an expansion ratio with a value of at most 8. The rotary engine may be part of a compound engine system.

Claim (Index 14):
The compound engine system as defined in  claim 13 , wherein an expansion ratio r EXP  of the rotary engine is defined by V MAX + V R V MIN + V R , where V R  is a volume of any recess defined in the peripheral surface between the adjacent ones of the apex portions, V MAX  is a maximum volume of a chamber defined between the peripheral inner surface of the rotor cavity and the peripheral outer surface of the rotor during rotation of the rotor, and V MIN  is a minimum volume of the chamber, the expansion ratio having a value of at most 8.
