  • Publication number: 20160076424
    Abstract: A system and method for heating main unit containing host salt having ammonia that is used as reductant in an engine exhaust gas after-treatment system. Engine coolant is delivered from internal combustion engine to auxiliary heating device. When necessary, the auxiliary heating device heats the engine coolant to temperatures that will aid in releasing ammonia from the host salt. The auxiliary heating device may employ an electric heating element, a combustion element, or be an exhaust gas heat exchanger, among other heating methods. The heated engine coolant is delivered to a coolant heating manifold, where heat from the heated coolant is transferred to the main unit. The transferred heat may aid in elevating the temperature in/of the main unit to facilitate the release of stored ammonia from the host salt as a gaseous reductant. The gaseous ammonia may then flow from the main unit.

  • Patent number: 9248815
    Abstract: A method for automatically decelerating a vehicle having a first side with a first front wheel brake and a first rear wheel brake and second side with a second front wheel brake and a second rear wheel brake, and in which the vehicle further has a braking system with a pump operable to deliver a flow of pressurized hydraulic fluid to the first and second front wheel brakes and to the first and second rear wheel brakes, includes receiving a signal associated with an emergency braking event. The method further includes increasing the hydraulic pressure at the first and second front wheel brakes at a greater rate than at the first and second rear wheel brakes. The method also includes directing hydraulic fluid from the first front wheel brake to the second rear wheel brake upon achieving a targeted level of deceleration or wheel slip.

  • Publication number: 20150101675
    Abstract: A reductant storage and dosing system which uses at least one canister containing a supply of reductant to supply, via a delivery line, an exhaust gas after-treatment system having an injector is disclosed. A controller may be used to meter the flow of the reductant through the delivery line to the injector, while a status indicator indicates a status of the connection—i.e., connected or disconnected. In an embodiment, the status indicator provides a visual signal or indication, such as an LED or series of LEDs, an audible signal, such as a beep, click or buzz, or both. Iternatively, the status indicator may be an analog or digital gauge.

  • Publication number: 20140325964
    Abstract: A system and method for delivering a reductant into an engine exhaust stream for use in the reduction of NOx is disclosed. The system includes a cartridge having an interior space for storing the reductant containing material, a fluid supply line fluidly connected to the cartridge for receiving the reductant, a pressure boosting device for boosting the flow of reductant, a flow management device, and, an injector for injecting the reductant into an after-treatment system for combining with the exhaust stream. The reductant may include ammonia. Use of the pressure boosting device increases the reductant pressure into the aftertreatment system, providing for a reduction in the time to inject the reductant into the exhaust stream, while improving the distribution of reductant into the exhaust stream.
