RE: New Evolution 10cc gas engine
Interesting concept.
FWIW- all IC engines are simply air pumps and as such have an rpm envelope where flow is maximized . (maximum torque)
if the engine can not reach this rpm- power is reduced .
Also above this envelope , flow again is reduced - per cycle but may increase over a given time period (rpm)-and HP can increase.
Electric motors don't have these constraints.
max torque can occur at zero rpm
