How does that work? I'm talking about the main page.

If I could block their channels like Black Lie Smatter and Free With Ads, that would be great.

OK Here was an engine that still had some kind of connecting rods but not the same as standard engines: THE Bourke Engine.

I have a large report on the engine, it WAS built and run.

Here are some excerpts from this article: Bourke-Engine : Bourke 30

And this from the article: Bourke Engine Documentary - Bourke Cycle Edition

"The Bourke Engine Ran With A 50:1 Air/Fuel Ratio And Produced More Horsepower & Torque Per Pound Than Any Other Engine In History. It Had Only 2 Moving Parts, The Oil Never Had To Be Changed, It Was Very Quiet, And It Ran Very Cool. At nearly 70% thermal efficiency, it's the most efficient gasoline engine ever made!"
REVEALED: The most important gasoline engine ever made, where it came from, how it works and how to build one.

Sadly this page is also SELLING info on this engine so be warned.
None the less there is a ton of info in these pages…this could be very worthwhile looking deeply into these claims.

Free info at en.wikipedia.org/wiki/Bourke_engine


en.wikipedia.org/wiki/Bourke_engine#Engineering_critique_of_the_Bourke_e ngine lists 12 points. The Scotch Yoke is a deal-killer for me.

"The Scotch Yoke is a deal-killer for me."

Why??

I can see the write up is not accurate, the 4 cylinder version of this engine was a 4 cylinder boxer engine like the VW.

As far as I have read it ran up to 50:1 A/F radio, and it fires on each compression stroke which is each time the piston compresses, plus the power stroke of a firing piston helps compress the other side piston.

Anyway this is a very interesting design and should be researched more.

Sliding friction vs rotating friction.

Which is why I liked the example at Permalink #1.

I had never seen most of these designs ... fascinating! That's why I like this forum - no matter how much you think you know (or are aware of), somebody always manages to come by with new and interesting stuff! ;-)

racprops — I opened both links and Cmd-F 'skipper' gets 0/0 on both. DDG 'bourke skipper bearing' yields sail boating links.
