Patent number: 10605138Abstract: An exemplary embodiment includes a blending chamber having a urea inlet, a blending chamber gas inlet, and a blending chamber outlet. A urea source provides a pressurized urea solution to the urea inlet at a urea injection pressure, and a pressurized gas source transmits pressurized gas to the blending chamber gas inlet via a passageway. The passageway is configured to decrease pressure of the pressurized gas transmitted along its length from a first pressure of gas received from the pressurized gas source to a second pressure of gas provided to the blending chamber gas inlet. The first pressure of gas received from the pressurized gas source is greater than the urea injection pressure and the second pressure of gas provided to the blending chamber gas inlet is less than the urea injection pressure.Type: GrantFiled: February 13, 2018Date of Patent: March 31, 2020Assignee: Cummins Emission Solutions Inc.Inventors: George L. Muntean, Steve Holl, Joydeep Chakrabarti, John Anthis, Joshua D. Henry, Samuel Johnson, Andrew Myer, John K. Heichelbech

Patent number: 9719392Abstract: 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: GrantFiled: March 2, 2017Date of Patent: August 1, 2017Assignee: Cummins Emission Solutions Inc.Inventors: Aalok Trivedi, Andrew Myer, Stephanie L. Apewokin, Samuel Johnson, Srivardhan Chandrapati, George L. Muntean, Joshua D. Henry, John Anthis, Omkar Tendolkar
