  • Status indicator for amonia cartridge
    Patent number: 9322695
    Abstract: Systems and methods for determining amount of solid ammonia stored in a canister used in providing ammonia fluid in exhaust gas after-treatment systems. A microcontroller sets an ammonia level based on the data read from an RFID tag associated with the canister. The data may provide the amount of solid ammonia stored in the canister or a tag number that the microcontroller may use to retrieve the quantity of stored solid ammonia. A measured amount of ammonia fluid used during the treatment process may be used by the microcontroller in determining the amount of solid ammonia depleted from the canister. At predetermined precisions, the amount of depleted ammonia is subtracted from the set ammonia level to determine the remaining amount of solid ammonia in the canister. This determined amount of may be used to reset the ammonia level and be written onto the RFID tag.

  • THERMOSTAT
    Publication number: 20160108797
    Abstract: A thermostat for controlling the flow of a coolant into a radiator and a bypass circuit is provided. When the bypass circuit is to be closed, the thermostat displaces a shaft that is operably attached to a bypass plate. When in the closed position, the bypass plate is configured to engage a top wall of the bypass circuit so as to prevent the flow of coolant into the bypass circuit. To minimize the formation of a water pressure pulses generated by the closing of the bypass circuit, only a portion of the bypass plate initially contacts the top wall. Such limited contact allows for the restriction of the flow of coolant into the bypass circuit, and interrupts the even flow of coolant around the bypass plate. Such restriction and/or interruption allows for the gradual closing of the bypass circuit, which minimizes the associated water hammer effect.
