That's why natural gas autos have such clean emissions.  The problem is
atomization.  Liquid doesn't burn...gasses do.  The problem is getting the
liquid to become a gas (ie. atomization).  This is affected by the spray
pattern of the injectors, the pressure, air temperature, intake design,
cylinder design, valve design, etc.

I can't say I'm an expert, but IMO this is the basic root of the problem.  If
atomization is complete, the emissions will go way down.  However, the basic
chemicals makeup of gasoline make it prone to produce more hydrocarbons and
carbon monoxide than other combustibles.
