  • Apparatus and Method for Preventing and Removing Carbon Deposits
    Publication number: 20160047284
    Abstract: Oxyhydrogen (HHO) generated by an HHO generator hydrogenates solid carbon to liquid and gaseous hydrocarbons in the exhaust system of an internal combustion engine, such as in the particulate filter of a diesel engine to clean the solid carbon from the particulate filter without conventional regeneration. Discharge of the HHO to the exhaust system also reacts with NOx in the exhaust gas to reduce the NOx. The HHO may be discharged to a plurality of locations to clean solid carbon and reduce NOx emissions from a diesel engine.
