Bourke is Otto cycle taken to its' extreme.
The roller cam assembly spins as a flywheel, independent of the rod-yoke assembly. Counterweights correct only for the mass of the journal bearing. It is strobe balanced to 10k by removing small amounts of material from the counterweights...

I have what you request on floppy disc- Microsoft spreadsheet. It will be posted as soon as we can get it to our site manager.
Thanks for the heads-up on safety. Early-on it was a little scary, but as I gained confidence that it wasn't going to explode, I got a little closer to it.
Were it possible that Russ Bourke was unknowingly doing HCCI in 1936? Homogenous charge compression ignition, about which I learned from this forum, fits his descriptions perfectly. Honda's "active radical" engine can maintain this condition for 15% of the powerband. Once "in cycle", Bourke's...
If anyone believes this hobbiest is fraudulent, you are mistaken. I have tried to unravel the Bourke engine since 1979. Bourke said we would have to "shake off our preconceived notions" while working with them. Bourke is an unusual animal in that it can produce a smooth flow of power from...
Since the design is clearly "unbalanced", how does it run so smoothly in the video? Rethink the dynamics. I was skeptical, but it can and does run very smoothly, and maintains its' character for all RPM's. One ignition piick-up is moved ever so slowly , while running, so as to achieve the "null"...
Wow! Looks like old Russ Bourke is still stirring the I/C pot.
There are no hidden weights. Bourke's dynamic balance works exactly as he describes it. I ripped more than one lord mount trying to get the cylinders in sync. All forces are equal and out of phase by exactly 180 degrees. We have a...
Obviously lots of questions about the Bourke Cycle.
Oxides of nitrogen are avoided by not being produced in the first place. Combustion chamber temperature is lower than that needed to produce NOx.
F/A ratio as lean as 24/1. Excess air.
Low E.G.T is the result of the expansion of the spent...
Russell Bourke invented the perfect lean burn engine in 1938, in which detonation is harnessed and not shunned. "The Bourke Engine Documentary" manual will put all of these issues into perspective. If you want the facts behind his amazing engine, please see <http://bourke-engine-project.com>
Hello group, Having found this group listed #2 on a Google search for "Bourke engine", I offer my site on the Bourke engine. I have researched and run O.E.M. Bourke 30 C.I.D. engines, as well as my own homebuilt prototype powering a 15 Kw Hobart generator. At <http://bourke-engine-project.com>...
