    Abstract: A sensor and housing assembly may include a sensor configured to detect a quantity of a gas in engine exhaust, and a housing including an inner upstream wall, a first inner side wall having a sensor opening for the sensor, an inner downstream wall opposite to the inner upstream wall, and a second inner side wall opposite to the first inner side wall, and having a housing inlet and a housing outlet that is opposite to the sensor opening in the first inner side wall. The sensor is positioned within the sensor opening on the first inner side wall, and a tip of the sensor protrudes through the housing outlet.

    Abstract: An exhaust pipe includes a first end, a second end, and a wall connecting the first end to the second end. The first end has a first opening, and the second end has a second opening that fluidly communicates with the first opening to define a bore. The wall includes an inner curved second and an outer curved section that includes an indentation. The indentation includes a first inwardly extending part and a second inwardly extending part. The second inwardly extending part includes a through hole having an inner opening and an outer opening. The inner opening is located between the outer opening and the second opening. A diameter of the outer opening is less than a diameter of the inner opening. A thickness of the second inwardly extending part is less than the diameter of the outer opening.

    Abstract: A method and system for modeling growth of reductant deposits for an aftertreatment system on a real time basis using input including exhaust gas temperature, exhaust gas flow rate, and reductant dosing rate. The growth of the reductant deposits are affected by a rate at which reductant accumulates and decomposes from a surface of the aftertreatment system. Thus, the method and system disclosed determines a net reductant deposit growth rate value based on a reductant deposit accumulation rate value and a reductant deposit decomposition rate value. Further, the method and system disclosed determines a reductant mass deposit value based on the net reductant deposit growth rate value. The reductant mass deposit value determined by the method and system may then be used to control a regeneration strategy of the aftertreatment system to eliminate the reductant deposits from the aftertreatment system.

    Abstract: An engine system is provided. The engine system includes a passageway having an inner surface and an outer surface. The passageway is adapted to allow a flow of air therethrough. The engine system also includes a sensor provided in the passageway and in contact with the air. The sensor is adapted to sense a parameter of the air. The engine system further includes a hydrophobic coating having a micropatterned texture provided on at least one of the inner surface of the passageway and the sensor. The hydrophobic coating is adapted to limit deposition of at least one of a fluid and a solid thereon.

    Abstract: A coolant system for a reductant tank is disclosed. The coolant system includes a valve configured to control a coolant flow to the reductant tank. The coolant system also includes a cyclonic filter element provided in fluid communication with the valve. The cyclonic filter is positioned upstream of the valve with respect to the coolant flow. The cyclonic filter is configured to separate particulate contaminants from the coolant flow to create a filtered coolant flow. The cyclonic filter is also configured to direct the separated particulate contaminants away from the valve. The cyclonic filter is further configured to provide the filtered coolant flow to the valve.
