A nutating internal combustion engine is disclosed including a disc (110) having cone-shaped surfaces and a centrally disposed sphere (100) positioned within a symmetrical spherical-segment shaped chamber (300) which is adapted to contain the disc (110) and has a central bearing to movably engage the sphere and to allow the disc to nutate within the chamber to turn drive shafts (210, 220). Preferably, the engine operates on a four cycle principle and combines the intake and compression chambers into a single chamber and the combustion and exhaust chambers into a single chamber to fire every 180 degrees.

Why it's free to use
- Filed December 29, 1992 and granted May 13, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 29, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 29, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
