And I bet that in 2006 they had not discovered what a problem NOX was to become.

I still believe vaporizing can still greatly improve an engines fuel mileage and lower pollution.

NOx actually drops above a certain AFR, because combustion starts to cool off again. Nonetheless, Honda added a second catalyst to the USDM Insights which was designed chemically to specifically break down NOx - a NOx trap, if you will.

And, it will hold a 24:1 AFR out to around 95% load. Above that it drops to stoich, though this is probably more because of power expectations with the pedal to the floor.
