In order to work the mixture must be in a narrow range - stoichemic - which is neither good for mileage or power. What happens is that an engine must pump out crap so the secondary scrubber can work and clean the crap up. Typical government non-thinking. Virtually all work on running on lean efficient mixtures has stopped because its a waste of time as long as devices are mandated and not numbers. Until numbers matter more than devices, no one will ever see high efficiency transportation.

Please accept my apology for my moment of insanity - just got off freeway from my normal daily 2 hour 70 mile daily LA commute "When some one gets something for nothing - some one else gets nothing for something " If the first ingredient ain't Habanero, then the rest don't matter.
