Just to slightly sidetrack things, have you seen this Ed?

Yeah, they had one of these on display at my local Honda Powerhouse bike
shop, and the owner spent some time showing it to me. Very interesting.


You've seen it in person? I'm envious........

Here's a good article on fuels and detonation (gasoline based).

Back in the early eighties Toyota had a real nice experimental 2
stroke engine. It was, IIRC, a 2 liter engine. All ceramic, valve
operated 2 stroke with a wet sump crankcase and pressurized bearings,
running a positive displacement supercharger like the old JIMMY
diesel.
They figured the fuel economy and efficiency would have been
significantly better than a 4 stroke, with lower HC and CO emissions.
Only problem was it was to operate somewhere well north of 600 degrees
F and NOX was a severe problem
