  • Patent number: 10605135
    Abstract: A method includes determining, by a controller, a total emissions amount from a plurality of engines; comparing, by the controller, the total emissions amount to a predetermined threshold, wherein the predetermined threshold includes an alert value, an adjustment value, and a deactivation value, the deactivation value being greater than the adjustment value, which is greater than the alert value; deactivating, by the controller, at least one engine in response to the total emissions amount being at or greater than the deactivation value; adjusting, by the controller, operation of at least one engine in the plurality of engines in response to the total emissions amount being at or greater than the adjustment value but less than the deactivation value; and providing, by the controller, an alert in response to the total emissions amount being at or greater than the alert value but less than the adjustment value.
    Type: Grant

  • Patent number: 9890677
    Abstract: An apparatus for controlling a total emissions amount from a facility includes an emissions module structured to interpret data indicative of an emissions amount from a test cell system in the facility; an emissions threshold module structured to aggregate the emissions amount from each test cell system in the facility to determine a total emissions amount for the facility and compare the total emissions amount to a predetermined threshold for the facility; and an aftertreatment system control module structured to selectively control a component in an aftertreatment system associated with each test cell system responsive to the comparison of the total emissions amount to the predetermined threshold.
