One of the distinguishing features is that they don't need valves to operate. That's to say, the Wankel rotary engine design doesn't have valves — but quite a few rotary engine designs have ...

This means it is a reciprocating rotary engine. Yeah, weird stuff. The camshaft is also centrally located in the crankcase ...

The engine is giant, gorgeous ... In addition to the lack of failure points—you don't need valves on a rotary—the need for it to run at wide-open-throttle for hours sounds like solid ground ...

The redline was set at 6,000 rpm, but the engine could actually go much higher as it doesn't contend with valve float or the damage from pistons being jerked back and forth too fast. A rotary ...

The rotary engine uses the same principles as an internal ... and they are released through a gap on the side of the housing, and no valves are needed. Wankel's original design had an outer ...

(Remember, the combustion rotors are located outboard of these valve rings and intake plenums.) See All 13 Photos As with most rotary engines, air primarily flows in and out through ports in the ...

Felix Wankel’s rotary engine is an engineering marvel because of its simplicity. Rather than the conventional pistons, camshafts, valves, and lifters, his design has a roughly triangular-shaped ...

Mazda might have already confirmed a rotary engine as a range extender for the ... Specifically, Mazda has reinvented the concept of variable valve timing for a rotary range extender, although ...

rotary engines have a triangular-shaped rotor that spins on an axis. They also have no valves which contributes to far fewer moving parts.
