Interesting 4 cycle engine

[Noitoen]

I saw this engine a couple of years ago and thought it's quite interesting.

That's pretty interesting. There was an engine that Smoky Yunick had designed years ago. It was designed to have rotary valves in the cylinder head. That had to be in the late 70's. Then in the 90's a company called Coates Engines had a prototype cylinder head of a similar design.

Helder,

I have a friend who bought one of those, they are easily available here.

It is one of the smoothest and quietest running four strokes I have ever seen.

As far as I know, they also make them for use in ROV aircraft, not just for models.
