发明名称 Exhaust system having regeneration temperature control strategy
摘要 An exhaust system for use with a combustion engine is disclosed. The exhaust system may have an exhaust passage configured to receive a flow of exhaust from the combustion engine, a particulate filter located within the exhaust passage, and a heating device located to selectively warm the flow of exhaust passing through the particulate filter. The exhaust system may also have a controller in communication with the combustion engine and the heating device. The controller may be configured to continuously determine an amount of particulate matter within the particulate filter, continuously determine a desired regeneration temperature based on the amount of particulate matter, and continuously determine an error value as a function of the desired regeneration temperature and an actual regeneration temperature. The controller may be further configured to determine an amount of particulate matter within the particulate filter, and adjust an amount of warming provided by the heating device based on the error value.
