The fascinating Hüttlin Kugelmotor spinning piston hybrid motor

Hüttlin Kugelmotor Could Revolutionize Extended Range

The new hybrid Hüttlin Kugelmotor could extend the life of internal gas engine, making it a perfect fit for future plug-in hybrids and other extended range-like vehicles.

The Hüttlin Kugelmotor has have arrived and if you haven’t heard about, you’re not the only one. The little, compact and highly unorthodox internal combustion fits somewhere between a Wankel rotary engine and a more tradition piston system. In a nutshell, it’s two sets of opposing pistons, following a sine wave shaft, spinning a cam turning a rotor inside a stator.

Das Hüttlin Kugelmotor. What is it, who did it, what are you talking about? The Hüttlin Kugelmotor motor is an inventive take on what a more efficient internal combustion should look like. By radically moving away from traditional pistons, it uses two pairs of opposite pistons spinning around a crack. In some ways, it looks like a rotary engine but it still has pistons. The rotating pistons spin around a rotor, thus bridging a gasoline piston engine and an electric motor. Confused yet?
