Hi guys! Did you miss me? Anyway, ive been reading up on the last two threads, and i have been thinking, what if you had dual injectors for each cylinder. Use a direct-rail system for each strip, and injected oxyogen by one and propane by the other? or hydrogen, but im not as big on that due to the molecular size. As the computer would automaticaly sense the amount of oxyogen being left out due to current o2 sensors, you could re-calibrate the system, get a really clean burn, get fairly good mileage and have a low-emmision system at high timing. I know this seems simplistic, so whos going to tell me whats wrong with it? Streets, Tech, Don, heres looking at you
