Jacob Backhaus has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Systems and methods for decreasing time to reach light-off temperature
    Patent number: 11834978
    Abstract: A vehicle system includes a diesel oxidation catalyst. The vehicle system includes a hydrocarbon-selective catalytic reduction unit located downstream of the diesel oxidation catalyst. The hydrocarbon-selective catalytic reduction unit is configured to receive exhaust gas from the diesel oxidation catalyst. The vehicle system includes a turbocharger located downstream of the hydrocarbon-selective catalytic reduction unit. The turbocharger is configured to receive exhaust gas from the hydrocarbon-selective catalytic reduction unit.
    Type: Grant

  • Reductant generation systems and methods
    Patent number: 10989088
    Abstract: A system comprises an engine including a plurality of cylinders. A first intake throttle is positioned upstream of a first set of cylinders of the plurality of cylinders. The first intake throttle provides air at a first flow rate to the first set of cylinders so as to produce a lean air/fuel mixture in the first set of cylinders. A second intake throttle is positioned upstream of a second set of cylinders included in the plurality of cylinders and in parallel of the first intake throttle. The second intake throttle provides air at a second flow rate to the second set of cylinders so as to produce a rich air/fuel mixture in the second set of cylinders.
