So did the Honda cvcc run a rich fuel mixture in the prechambers, while the combustion chamber was extremely lean? Causing the spark from within the prechamber to ignite the cylinder? Funny how such "groundbreaking" technology has been around for ages, it's just that now we're able to hone in these combustion processes at very precise levels. Nobody is reinventing the wheel, just making sure it can roll a little bit better...

I've also read articles that stated cost of emission control devices will go up if these powerplants are implemented in mass.
