Meet the Birotary, a crazy new and complicated engine that has three cylinders arranged like a star, a rotating block, a ...

The mind-bending world of birotary engines - a hybrid of piston and rotary technology that could revolutionize aviation. But ...

It has come to our attention that many of the top drag racing builders are overbalancing their engine assemblies. Basically, this is done to help high-rpm out-of-balance conditions and generate longer ...

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

I love weird engines—give me a rotary, a turbine, or, hell, even a flat-eight and I’ll be happy. That’s why I was so excited when I heard that INNengine of Granada, Spain had produced a opposed-piston ...

The road to 1,000 horsepower from pro drifter RAD Dan Burkett's Toyota 2JZ-GTE inline-6 engine ends here. We've shown you what goes into the rotating assembly guts of the beast; we've also shown you ...

German aerospace researchers are showing off a high-efficiency powerplant concept which combines geared-fan architecture with a piston-engine core. While unlikely to enter service before 2050, the ...
