Cam to cam no reg
In a four-stroke engine, these forces reverse cyclically: In the induction phase, the piston is forced upwards, against the reduced induction depression.The simple cam mechanism only works with a force in one direction.A relatively successful swashplate cam engine was developed by the bearing expert George Michell, who also developed the slipper-pad thrust block.Unlike a crankshaft, a cam may easily have more than one throw per rotation.
An early version of the Michel engine was a rotary engine, a form of radial engine where the cylinders rotate around a fixed crank.
The output work of the engine is driven by this cam. The first engine to get an airworthiness certificate from the United States government was, in fact, a radial cam engine.
A variation of the cam engine, the swashplate engine (also the closely related wobble-plate engine), was briefly popular.
Internal combustion engines, though, remain almost unknown.
Some cam engines are two-stroke engines, rather than four-stroke.
One advantage is that the bearing surface area can be larger than for a crankshaft.
