  • Publication number: 20220398876
    Abstract: A computing system is structured to receive operating data provided by a telematics circuit associated with a remote engine. The operating data comprises information provided by at least one sensor and/or at least one actuation command. The computing system is structured to determine, based on the operating data, a plurality of field-replaceable units (FRUs) associated with the operating data. The computing system is structured to generate a computer-based simulation corresponding to at least one degradation level for an FRU from the plurality of FRUs, identify a most probable failure, and rank the computer-based simulations across the plurality of FRUs. The computing system is structured to generate an electronic notification comprising data associated with the most probable failure and transmit the electronic notification to a computing device.

  • Patent number: 11352931
    Abstract: A method, system, and apparatus relating to operating an internal combustion engine include steps or features for determining a performance threshold of a particulate filter disposed in an exhaust gas flow of the engine having a set time interval between regeneration events of the particulate filter; determining a rate at which the particulate filter is reaching the performance threshold; and controlling an exhaust gas characteristic to control the rate so that the performance threshold is reached at or just before an end of the time interval. In an embodiment, there are steps or features for interpreting a filter condition of the particulate filter; determining a particulate matter load rate of the filter as a function of the condition; determining a limit of an exhaust gas characteristic based on the load rate; and controlling engine operation to control the exhaust gas characteristic to satisfy the limit.

  • Publication number: 20200400088
    Abstract: Systems and apparatuses include an a system including an engine out sensor, an exhaust sensor, and one or more processing circuits comprising one or more memory devices coupled to one or more processors. The one or more memory devices are configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to receive the engine out sensor information from the engine out sensor, receive the exhaust information from the exhaust sensor, determine the aftertreatment system characteristic based on the exhaust information, compare the aftertreatment system characteristic to an exhaust condition, determine an acceptable input value when the aftertreatment system characteristic meets the exhaust condition, and control at least one of a fuel system actuator and an air handling actuator to achieve the acceptable input value.

  • Patent number: 10767584
    Abstract: Systems and apparatuses include an apparatus including an aftertreatment system control circuit structured to receive a signal indicative of an exhaust gas characteristic from a sensor, determine an aftertreatment system characteristic based on the exhaust gas characteristic, determine an acceptable input value responsive to the aftertreatment system characteristic, and control at least one of a fuel system actuator and an air handling actuator to achieve or substantially achieve the acceptable input value.
