Abstract
An internal combustion engine featuring a radial array of cylinders and pistons; the pistons having rods including cam followers engaging the surface of a cam drive to transfer reciprocating linear motion into rotary motion; wherein between the piston rods and the engine housing are disposed arrays of toothed rollers to provide a rolling interface.
Claims16
An engine comprising:
- two shells, which comprising a plurality of cylinders and a plurality of toothed tracks,
- a plurality of pistons, wherein each of the plurality of pistons is configured to move inside one of the plurality of cylinders;
- wherein each piston comprises toothed tracks and wheels;
- a plurality of arrays of toothed rollers, each array of toothed rollers configured to roll between and mesh with one of the toothed tracks of one of the pistons and one of the toothed tracks of the shells;
- a cam, named power-cam, comprising tracks, wherein the cam is configured to drive the pistons, via the wheels of the pistons and the tracks of the cam, and to force the piston's motion along the piston-top motion curve (1H);
- a plurality of cylinder heads;
- a valve timing mechanism;
- a fuel supplying system and
- an ignition system.
