Thanks for the book leads, Fred, I'll have my librarian friend see if she can borrow one or more for me. I met Gordon Jennings briefly several (6-8) years ago when he visited us at General Motors Engineering Staff, he was a neat guy. Yes, almost all the fellows and gals involved with our 2-stroke cycle program (except a couple new hires) were 4-stroke people. (fresh off the design of the SATURN engine, if I remember) One guy came from Ireland, University of Dubland, I think, and there were some with a Detroit Diesel background, but hay, where are you going to find 2-stroke talent in the heart of GM's advanced engine design community? And no, he wasn't ignored at all, the team knew that there was a universe of knowledge that they lacked when they began the program, and there was a lot of skepticism of the information that was being provided by the Austrailians. It finally ended up that, like the Wankel rotary engine program thet proceeded it by at least a decade, the two-storke engine could not be made to meet the current, proposed, and expected federal and state vehicle exhaust emissions standards and it was dropped.
