Jonova engine

The Jonova engine / Jonova Motor is a type of rotary engine, designed originally by John Nowakowski - its name was given to a recent design by student engineers at the University of Arizona.

Consisting of only four moving parts, the newer Jonova engine loses no energy through vibration and has a wide power stroke of over 2/3rds of its rotation, as opposed to piston-cylinders which have power for only a 1/4 of their rotation.
