Before getting to the engine and its engineering I'm going to make a few observations, and express a few acerbic opinions. 

I'm also going to relate a few lessons I've learned while patenting and working on my inventions which I expect will help other inventors protect their endeavors.

If you're an individual who might some day file for a patent in the U.S. and wish to avoid the problems I've experience while patenting and developing a substantial new technology, I suggest you use a patent attorney.

Subsisting on a social security disability pension negated this option for me.

In addition to filing your application for patent at the U. S. Patent and Trademark Office (PTO), use the Patent Cooperation Treaty and file additional applications in at least two other countries. 

Multiple filling will give your formal documentation two additional "secured" locations for reference.

The foreign patent platform documentation can still be relied upon for original content, in the event that your records, your attorneys records, and the PTO records are all criminally modified (not an impossibility).

Your attorney might even advise filing your initial application in a foreign country.
