Internal combustion engine system and method with reduced noxious emissions

For use in conjunction with a combustion-based system including a combustion chamber having an exhaust, a source of input air and a source of fuel for providing input air and fuel to said combustion chamber, means communicating with said combustion chamber for obtaining power from said combustion, and a chemical for reacting with a component of noxious emissions of the combustion chamber exhaust;

• the improvement comprising:
• an ultrasonic fogging device communicating with said input air, said fogging device being adapted to receive a fogger air supply and a fogger water supply, and to generate a fog in said source of input air;
• means for sensing noxious emissions in exhaust gases from said combustion chamber;
• means for combining said chemical with the water supplied to said fogging device at a rate which depends on the sensed noxious emissions.
