Okay Lets look at how the Bourke Engine works and why its a gas guzzler.

The Bourke cycle

1. Intake air below the piston. (fine)

2. Compress the intake charge below the piston

3. Let the intake charge that you expended energy on to compress decompress into top the cylinder above the piston with out extracting a bit of energy back out of it. (oops... wasted energy)

4. Compress the intake charge again.

5. ignite the compressed charge and hold it compressed while it burns around top dead center as long as possible. (oops.... we are letting all the heat energy dissipate into the combustion chamber walls)

6. Extract power from the combustion gasses that we have allowed to cool at top dead center and thus allowed significant energy to already escape.

7. exhaust the spent gasses.

Inefficient no matter how you look at it. Want to claim it runs in detonation mode making it efficient like a pulse detonation engine? Detonation in an internal combustion engine does nothing more than scrub combustion gasses against the combustion chamber walls via echoing shockwaves and loose more heat to the cooling system thus making it more inefficient. Want more proof of how inefficient it is? Look at the size of the heat dissipation fins on the engines that Russell Bourke built.

The Bourke engine is a scam just like browns gas and HHO. Backers of this
scam have even published a book about it and tried to post date it and claim it was published by the Experimental Aircraft Association in 1968 to give it credibility. Unfortunately its easy to look up and see that The Bourke Engine Documentary doesn't appear in a list of Experimental Aircraft Associations published works. Further digging will reveal it was first published in 1990 by Tesla Books.

These scam artists have done nothing but collect a few examples of a bourke engine, set up a web site, hype it, and ask for money to run tests that they will never do.
