摘要： Systems and methods for controlling and managing ammonia slip are provided. A method includes: receiving, by a controller, data regarding operation of an exhaust aftertreatment system; determining, by the controller, that a condition for ammonia slip is present based on the data regarding operation of the exhaust aftertreatment system; determining, by the controller, that a condition for ammonia storage is present based on the data regarding operation of the exhaust aftertreatment system; and, commanding, by the controller, a heater to activate and warm a component of the exhaust aftertreatment system to reduce the stored amount of ammonia.

摘要： A internal combustion engine system includes a gasoline internal combustion engine having a set of donor cylinders and a set of non-donor cylinders. The donor cylinders provide a proportion of the exhaust gas to an exhaust gas recirculation system and the remainder of the exhaust gas to an exhaust gas aftertreatment system including a particulate filter. The non-donor cylinders also provide exhaust gas to exhaust gas aftertreatment system. An engine controller can determine whether the particulate filter needs regeneration, and in response, retard a spark timing of the non-donor cylinders by an amount that is different from an amount or retardation of the donor cylinders.

摘要： A method includes determining, by a controller, that a transient event for a hybrid vehicle is occurring; determining, by the controller, an increase of power demand for the hybrid vehicle based on the determined transient event; directing, by the controller, an amount of power from an electric motor of the hybrid vehicle to a powertrain of the hybrid vehicle based on the increase in power demand, the amount of power from the electric motor determined based on at least one of a state of charge of a battery of the hybrid vehicle; and increasing, by the controller, an amount of power from an engine of the hybrid vehicle as a power output from the electric motor decays to avoid an engine power output spike from the engine based on the determined increase in power demand.

摘要： A method for managing emissions from a vehicle having an aftertreatment system is provided. The method includes: receiving, by a controller, information indicative of a temperature of an aftertreatment system of the vehicle and a power output of an engine of the vehicle; comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold; comparing, by the controller, the power output to a power output threshold; and responsive to the comparisons, commanding, by the controller, an aftertreatment system heater to selectively engage and disengage to warm the aftertreatment system of the vehicle.

摘要： The enclosed disclosure relates to vehicle systems in which an engine, a particulate filter fluidly coupled with the engine, a selective catalytic reduction (SCR) system fluidly coupled with the engine downstream of the particulate filter, an electrical heating device implemented with the particulate filter, and a controller operatively coupled with the engine and the electrical heating device, are implemented. The controller can detect, when the engine is turned off, a condition for turning on the engine, detect a temperature of the particulate filter of the SCR system, activate the electrical heating device in response to the detected temperature being below a lower temperature threshold, and turn on the engine in response to the detected temperature being at or above the lower temperature threshold.

摘要： A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to, determine that the catalyst is operating under cold start conditions, control the bypass valve to direct exhaust gas to the PNA, determine that the catalyst is no longer operating under cold start conditions and continue to control the bypass valve to direct exhaust gas to the PNA for a predetermined duration, and after the elapse of the predetermined duration, control the bypass valve to direct exhaust gas to the catalyst bypassing the PNA. The controller is also configured to detect a high transient torque demand while the exhaust gas is provided to the PNA, and split the torque demand between the engine and an electric motor.

摘要： A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to: while controlling the bypass valve to direct exhaust gas to the PNA, detect a torque demand that is greater than a threshold value; responsive to detecting that the torque demand is greater than the threshold value, engage a motor, coupled with a battery system, with a drive shaft of the system to meet at least a portion of the torque demand; in response to the engagement of the motor with the drive shaft not meeting all of the torque demand, engage the engine with the drive shaft to meet a remainder of the torque demand.
