  • Systems and techniques for nozzle cooling of diesel exhaust fluid injection systems
    Patent number: 9719392
    Abstract: A system is provided for delivery of diesel exhaust fluid or other reductant to an injector for release into an engine exhaust aftertreatment system. The injector includes a nozzle assembly that thermally shields the diesel exhaust fluid from the exhaust gas temperatures. A diesel exhaust fluid delivery procedure is also disclosed for nozzle cooling prior to operation of the injector for emissions reduction.
    Type: Grant

  • Ammonia generation system for an SCR system
    Patent number: 9353665
    Abstract: A system including a reductant source storing reductant, an ammonia generation system configured to generate gaseous ammonia via cavitation, and a gaseous ammonia delivery device in fluid communication with the ammonia generation system and an exhaust system. The system may selectively activate the ammonia generation system responsive to a detected temperature of an exhaust gas of an exhaust system being equal to or below a predetermined value. The ammonia generation system may utilize ultrasonic cavitation or laser cavitation to generate gaseous ammonia to be delivered to the exhaust system responsive to the temperature of the exhaust gas of the exhaust system being equal to or below the predetermined value. If the temperature of the exhaust gas of the exhaust system above the predetermined value, a dosing module to dose reductant to the exhaust system may be activated.
