I am renewing knowledge of this very interesting engine...

Guys your really need to look into all the information here:

https://www.bourkeengineprojectllc.com/

I ran into a guy with photo copies of the scraped together book by Mr. Bourke about the engine... it was a bit of a mess.

It has been cleaned up and is much better form now.

Now if I was struck rich I have a second dream to build, and this engine just might be number one ahead of Gasoline vapor.

I can see the slipper bearing. Now I have to figure out what the transfer port does.

My favorite interesting engine is the Scuderi split-cycle engine, and it has a transfer port. But it's 4-cycle so probably not much likelihood of combining the two, although the Scotch Yoke might carry over.



I guess the 15 crank offset is a problem.

Scuderi split-cycle still sounds more down-to-earth compared to other breakthrough designs.

Seems silly, to use a whole piston to do a pre-compression, when a simple super charger, or turbo charger is so much better at cramming in air.

As in a 2-stroke Diesel?

The magic is that the transfer port can be a compressed air tank. So it can run as a compressed air engine. Engine compression is ~150psi, SCUBA tanks hold 1500psi.

Had it been combined with an electric compressor or other auxiliary air supply, could qualify as some sort of hybrid. Makes me wonder to which extent DFCO and engine-braking could be compared to the regenerative braking of a hybrid.
