Roger Richard’s protégé, Sky Huddleston, presented at the 2021 ESTC on the Bourke Engine and is the most comprehensive and authoritative presentation ever given on this technology.
Here is a relatively recent video demonstration by Roger Richard that you can watch here. Roger’s description is:
“I played with a trial video editor and got some interesting results. Sorry about the watermark, but I couldn’t wait to post it and used it anyway. The video is an overlay of two Bourke 30″ engines running about a second apart. Also, this run is with 87 octane pump gas . A slight modification of the original design made this possible. True homogenous charge compression ignition, HCCI. Russ Bourke was right and still is.”
