One cylinder is not enough.

Ha Ha. I wouldn't fly in a plane with a 1950s petrol engine, either. Like your average Lycoming.

Actually, I've written earlier on these posts quite a lot about the concept. I personally couldn't build a aircraft engine. I doubt if anyone after, what? - 1910 - could.

An aircraft engine should be designed just for that purpose - not a modified car engine.
There is a three cylinder engine which is not bad but I would like to see a V6 or V8. About 3 L capacity. But to build anything like that is beyond anyone other than an established manufacturer.

No, I wanted to convince a particular manufacturer that a certain design would have advantages that seem to have been overlooked. Central to this "proof of concept" is the inlet valve arrangement (which in my foto does not show final machining but never mind - - later) and gas flow. But there are six other advantages that follow and no disadvantages.

I can test the effectiveness of the idea (prove or disprove - I can't predict if that will work) best with an uncomplicated single cylinder engine. If the idea is right, then I can argue that "this is the way forward." (I doubt if anyone will listen which is the way of the world). But there is a manufacturer - & I know those guys well enough that they just might be interested.

But do you know, it cost Diamond/Centurion nearly a million Euros just dealing with the EU Regulators - proving that their motor is ultra reliable. Not manufacturing - proving it was safe. If it breaks down, the AA is a long way off!

So, no, I'm not building an engine to fly a plane. I'm building an engine which - if it does what I hope - will allow an aero engine to be designed using this concept.

All ze best
