  • Near-zero emitting diesel-electric locomotive using a high-speed diesel engine
    Patent number: 11739673
    Abstract: A diesel-emissions reduction unit having an inlet adapted to receive an exhaust stream of the diesel engine; a diesel oxidation trap catalyst located adjacent the inlet; a dosing controller and an injection lance arranged to meter aqueous NH3 into the exhaust stream; a NOx concentration sensor and a NH3 concentration sensor with at least one oxidation catalyst panel arranged to isolate the NOx concentration sensor from NH3 in the exhaust stream; and an exhaust heater arranged to heat the exhaust stream of the diesel engine toward the inlet of the diesel emissions reduction unit.
    Type: Grant
    Filed: September 30, 2022
    Date of Patent: August 29, 2023
    Assignees: Catalytic Combustion Corporation, Knoxville Locomotive Works, Inc.

  • Near-zero emitting diesel-electric locomotive using a high-speed diesel engine
    Patent number: 11499459
    Abstract: A diesel-electric locomotive includes a diesel emissions reduction unit, including an inlet configured to receive an exhaust stream of a high-speed diesel engine; means for trapping at least a portion of diesel particulate matter contained in the exhaust stream; an aqueous NH3 dosing system including a dosing controller in communication with an electronic locomotive controller and a nitrogen oxide (“NOx”) concentration sensor and an ammonia (“NH3”) concentration sensor, at least one oxidation catalyst panel arranged to isolate the NOx concentration sensor from NH3 in the exhaust stream; mixing elements located between the dosing system and the NOx and NH3 concentration sensors to mix metered aqueous NH3 in the exhaust stream; a selective catalyst reactor bed located between the mixing elements and the NOx and NH3 concentration sensors; and an exhaust heating system in communication with at least one of the dosing and electronic locomotive controllers.
