Weird? This is nothing new. In Germany they use these engines for small in-house power plants for heating and electricity. And the concept is used for the air conditioning compressor in nearly every modern car.

Looks like they've been reading the enginephile thread? :)

First used as an engine in torpedoes before world war 1.

Harrison V5 and V7 air conditioners are a variable stroke implementation of the same idea. Go to a scrapyard and get one if you are interested.

It's just a swashplate engine, I wouldn't call it new. It's been discussed at some length on this forum before.

This is a very typical swashplate engine, a design known well over 100 years ago when Steam was king and people were making steam engines with this kind of mechanism.

Now if you want a really revolutionary kind of engine, you'll have to wait until I get my design to run correctly.

I found a way to make a 4 stroke piston engine with only 3 moving parts, almost perfect balance, and really the only engineering issue that hasn't been addressed in the hundred years of engine building that has been done is the issue of keeping it sealed up tight- simply because of how I made it all work.

A proof of concept made from scrap metal just to see if mechanically it could perform has been demonstrated breathing fire on the test stand- but where it should be around 180 PSI compression I'm only getting about 45 PSI from it. Just getting reliable ignition at all with such a major compression leak is startling, and proves that I was able to get a usable timing diagram.

I have no crankshaft. No camshaft. No timing gears. No valvetrain. It looks like some type of jet engine, yet it has a typical small engine carburetor, sparkplug, and muffler. Fires twice per revolution, and by calculation I arrive at a very nearly 1:1 power to weight ratio, for an iron block without any boosting. If only it didn't leak so much.

How about a supercharged through scavenge two stroke with only one moving part.
Any investors out there?

Wouldn't that just be a jet engine?

Though I've heard of free piston two strokes that do this.

They use the brayton cycle. A single piston with a large diameter for the compressor and a small piston for the working cylinder with a common shaft, using piston-port valving.

The large piston compresses the charge in advance, and then when the small piston uncovers the port the precompressed charge rushes in driving the exhaust out, is compressed, by the spring and/or counterweight, and ignites it again driving the weight upward or compressing the spring- at the same time preparing the next charge.

There really hasn't been any new development in engine technology that can't be found in the engines of 100 years ago.

Even my design, all I did was took well documented concepts and put them together a little differently.

But despite being built out of scrap metal on a peanuts budget, it breathes fire. And I am currently drawing up plans for an even better one built with my recently improved budget that should have a lot less friction and much better sealing- hopefully enough to make it come alive.

My thoughts too, it is elegant and compact though.
