The crankshaft is, by far, the most massive moving part in your race engine. There's a reason for that-the crankshaft is essentially ground zero for every bit of the torque your high-buck race engine ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

Despite being in use for more than a century, combustion engines are still way to complex and inefficient in turing fossil fuel to mechanical work. Naturally, engineers have been battling their way ...

You're looking at one very clever piece of engineering. It's an Adams-Farwell air-cooled, piston-driven, rotary engine. The crankshaft stays put, connected to the frame of the car, while the crankcase ...
