David Mark Ginter 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).

  • Patent number: 9987612
    Abstract: A reactor assembly is provided. The reactor assembly includes a substrate and a first catalytic layer provided on the substrate. The first catalytic layer further includes a first temperature zone configured to operate at a first temperature. The first catalytic layer further includes a second temperature zone extending from the first temperature zone. The second temperature zone is configured to operate at a second temperature. The second temperature is lower than the first temperature. The reactor assembly also includes a diffusion barrier coating provided on the first catalytic layer. The diffusion barrier coating is configured to regulate a diffusion of gas phase oxygen therethrough for controlling the first temperature with respect to the second temperature.

  • Publication number: 20160160742
    Abstract: A spark plug arrangement is disclosed for use in an engine system. The spark plug arrangement may include a body, and a cap fixedly connected to the body to form an integral pre-chamber. The cap may have at least one orifice. The spark plug arrangement may also include an electrode extending through the body and at least partially into the pre-chamber. The electrode may be configured to create a spark in the pre-chamber. The spark plug arrangement may further include a capillary tube disposed within the body and configured to inject gaseous fuel into the pre-chamber to form an air and fuel mixture to be ignited by the spark in the pre-chamber.

  • Patent number: 8069654
    Abstract: Rhodium utilization in LNT/SCR-based exhaust after treatment systems for medium and heavy duty trucks is reduced by operating inline fuel reformers in a certain manner. The fuel processors are operated at steam reforming temperatures to produce a reformate-containing exhaust having a hydrogen to CO ratio of at least about 3:2 or at least about 3% hydrogen, This generally involves operating the fuel reformers at temperatures from about 500 to about 625° C. and with an overall fuel to air ratio from about 1.10 to about 1.40. In this manner, regeneration can be efficiently carried out while limiting the catalyst loading of the fuel processors to no more than about 1.0 grams rhodium per liter maximum displacement of the diesel engine and the catalyst loading of the LNTs to no more than about 0.50 grams rhodium per liter maximum displacement of the diesel engine.

  • Patent number: 7610751
    Abstract: One concept relates to power generation system, comprising a diesel engine, an exhaust manifold, a turbocharger, and an exhaust line in which are configured a fuel reformer and a LNT. A fuel injector is configured to inject fuel into the manifold upstream of the turbine. The high temperatures upstream of the turbine cause the fuel to crack into smaller molecules, releasing heat and providing a boost to the turbocharger. The fuel injected into the manifold also undergoes intense mixing as it passes through the turbocharger. Injecting fuel in this manner provides several benefits for reformer operation. Another concept relates to a manifold fuel injector used to provide fuel for heating a DPF.

  • Patent number: 6159442
    Abstract: Processes for use of a controlled continuous high pressure multiple reactant streams flowing into a chemical mixer/reactor. Individual reactant streams are pressurized to about 8,000 to 50,000 psi and achieve velocities up to about 250 meters/second in the final stage of the chemical mixer/reactor.
