Crankshaft Motion
Wasted motion robs power. A typical engine's crank is powered for at most 120 degrees out of every 720 degrees of rotation — only part of each third cycle. The crankshaft's motion is out of balance and unsynchronized. When you have pressure, there is little leverage. And by the time you have leverage there is very little power. |
vs. Roller Cam
Our engine applies power directly to rotation. The Circle 18SM uses a roller cam instead of a crankshaft. Six pistons fire every 10 degrees of rotation. Each of the 18 pistons fires 12 times in a full 360 degree rotation. This results in a much steadier torque. The engine's forces are balanced. Pistons are equal and opposed. The wave form of the cam transfers the force efficiently. |
