What are the advantages of Wankel rotary engines?
Advantages. A Wankel rotary engine has stronger flows of air-fuel mixture and a longer operating cycle than a reciprocating engine, achieving a concomitantly thorough mixing of hydrogen and air. The result is a homogeneous mixture and no hot spots in the engine, which is crucial for hydrogen combustion.
How fast do rotors turn in a Wankel engine?
Only the eccentric shaft spins fast, while the rotors turn at exactly one-third of the shaft speed. If the shaft is spinning at 7,500 rpm, the rotors are turning at a much slower 2,500 rpm. Pratt & Whitney Rocketdyne has been commissioned by DARPA to develop a diesel Wankel engine for use in a prototype VTOL flying car called the “Transformer”.
