Abstract
Abstract An ultrasonic fog generator can be used to advantage in injecting a fog into the input air of a combustion chamber, in order to improve the efficiency of the combustion chamber and reduce the noxious emissions in the exhaust. In accordance with a feature of the disclosure, a sensor is provided to sense the concentration of noxious emissions in the exhaust of the combustion chamber. The volume per unit time of the injected fog is increased as the concentration of the noxious emissions increases, and controlled to a preselected emissions setpoint. In accordance with a further feature of the disclosure, a supply of chemical suitable for reacting with a component of the noxious emissions is provided, along with means for combining the chemical with the water supplied to the fogging device.
