NOHC- No Over Head Cam
No Underhead cam, either!......I truly hope this is a real invention and not a pie in the sky toy. If applied, it could truly revolutionise the internal combustion engine. Complete digital control of the valves and injectors (piezo electrics)! The engine could be gasoline or diesel and run on 2,4,6 or 8 cylinders as needed!...........
Good one
