An engine exhaust after-treatment system is provided, which may include a particulate trap configured to remove at least some constituents of the exhaust flowing from an engine through an exhaust system. The system may also include a controller configured to collect in-service data related to an operating parameter indicative of the amount of time the engine operates. In addition, the system may include a memory device attached to the particulate trap and including a memory. The memory may be configured to store usage data indicative of how much time the particulate trap has been used in service. The memory may be configured to communicate with the controller to receive information related to the in-service data collected by the controller and update the usage data in the memory, based on the communication with the controller, to reflect a total amount of time the particulate trap has been in service.

A method of regenerating a particulate filter of an exhaust system of an engine system is disclosed. The method may include determining a condition indicative of an accumulation of hydrocarbons in the particulate filter, and monitoring the particulate filter to determine when to initiate regeneration of the particulate filter. The method may also include selecting a regeneration profile for regeneration of the particulate filter based on the determined condition, and regenerating the particulate filter in accordance with the regeneration profile.

Detecting ash in a diesel particulate filter includes receiving data indicative of signal attenuation for ash-responsive and ash-insensitive RF signals transmitted through a diesel particulate filter containing trapped soot and ash. A difference between the RF signals, such as a difference in signal attenuation, may be leveraged to detect a relative ash loading state or a change in relative ash loading state of the diesel particulate filter, and responsively indicate that filter cleaning is needed.

A method for operating an internal combustion engine includes compressing intake air using a compressor, supplying the compressed intake air to at least one combustion chamber of the engine, operating the at least one combustion chamber to output exhaust gas, and directing the exhaust gas to an inlet of a turbine configured to drive the compressor. The method also includes directing the exhaust gas from an outlet of the turbine to an exhaust system, bypassing at least a portion of the compressed intake air around the at least one combustion chamber, and adjusting a geometry of the turbine from a first configuration to a second configuration. The turbine is in the second configuration when the at least the portion of the compressed intake air is bypassed around the at least one combustion chamber.

A system for cold starting a machine is disclosed. The system may have an engine and a reductant tank. The system may also have a temperature sensor, which may be configured to generate a signal indicative of a temperature within the reductant tank. Additionally, the system may have a controller, which may be in communication with the engine and the temperature sensor. The controller may be configured to increase an operating temperature of the engine, based on the signal.
