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?

Technically Speaking. This hybrid engine, part of an electric motor is brilliant in many ways. By using a pair of opposing curved pistons spinning on a bearing, the two heads are pushed apart pushing the opposite pistons together. So far, this sounds like a normal internal combustion engine. Based on a four-stroke cycle, each of the piston heads is enclosed in a titanium ball bearing inside a circular axis shaped like a sine wave of sorts, making it a rotor. The other fixed circular axis that houses permanent magnets is the stator and when the pistons spin, you have electricity.

Since describing it is more difficult than words can convey, here’s a video of how it works.
