Russ Bourke devised an engine that would harness the destructive forces of
detonation, to produce a smooth flow of power, with minimal loss.
Bourke Engines embody attributes of the ideal internal combustion engine.

I taught myself CAD, so that I would be better able to really get intimate with Old Russ, and gain better insight into why his engines gained "legendary" status. The evolution and refinement of his design presented itself on my computer screen.
Bourke was very much misunderstood and ignored.
Dr. Diesel would stand in awe of a Bourke 400"
I applied several of the later 400 features to the Proto-30 to
reduce flexure of the yoke assembly, and simplify the
manufacturing process. Attention to detail-required.
The 200" reverse roller cam crosshead assembly.
The 400 is actually two coupled 200" units. Multiple twin
cylinder units can be coupled directly, or geared to a common
shaft. Modular engine layouts can provide many benefits.
Beefy roller cam assembly. Cranks and roller cams have
differences in geometry-Russ used them to advantage.
Precision roller yoke and rod assembly-heat treated and
ground. The rod most be absolutely straight and true.
Bottom view of 200" cylinder. I believe my CAD model is the most
detailed work you will find on this Bourke masterpiece.
