The Smartest Piston Engine You’ve Never Heard Of

In a world rushing toward electric vehicles, one engineer is quietly reimagining the internal combustion engine. Gary Way’s WY engine replaces the century-old crankshaft and connecting rod system with an innovative eccentric disc design, eliminating side-load friction, reducing weight, and improving efficiency. Built using off-the-shelf Honda parts, this working prototype proves that combustion technology still has room to evolve. From potential use as a hybrid range extender to running on alternative fuels like hydrogen, the WY engine offers a practical, versatile path forward. This is more than an experiment—it’s a challenge to the idea that combustion’s best days are behind it.
