摘要： An exhaust aftertreatment system for an engine is provided that includes a burner, an air supply system and a control module. The air supply system may be in fluid communication with the burner and may include an air compressor disposed upstream from the burner. The air compressor may include a pump mechanism, a clutch assembly selectively transferring torque from the engine to the pump mechanism, and a motor selectively driving the pump mechanism. The control module may be in communication with the clutch assembly and the motor. The control module may selectively switch the air compressor between a first operating mode in which the clutch assembly transfers torque from the engine to the pump mechanism and a second operating mode in which the motor drives the pump mechanism.

摘要： Methods and systems are provided for controlling the temperature and ratio of gases within a gas mixing tank reservoir and selectively charging/discharging gases from the reservoir to one or both of an intake system or an exhaust system. In one example, a method (or system) may include storing exhaust gas and/or compressed intake air into a gas mixing reservoir, and increasing or decreasing flow of coolant to the reservoir based on engine operating conditions. The stored gases may be discharged to an intake system and/or an exhaust system based on requests from a controller, and coolant flow to the reservoir may be adjusted based on the composition of the gases stored within the reservoir.

摘要： The present disclosure relates generally to aftertreatment of exhaust gases in internal combustion engines. The teachings thereof may be embodied in a method for operating a secondary air system comprising: measuring an actual pressure downstream of a pump of the secondary air system; acquiring a dynamic pressure based on the actual pressure, characteristic of changes caused by dynamic operation of the engine; acquiring a basic pressure based on peripheral conditions of the secondary air system; calculating a model pressure based on the basic and the dynamic pressure; determining a capacity of the pump based on a ratio between the model pressure and the actual pressure; and adjusting operation of the secondary air system based on the capacity.

摘要： A method for operating an engine includes selectively introducing air in an exhaust conduit upstream of a selective catalytic reduction system based on an exhaust gas temperature and a nitrous oxide conversion efficiency of the selective catalytic reduction system and changing at least one engine operating map for engine operation when the nitrous oxide conversion efficiency after introducing air is above a threshold nitrous oxide conversion efficiency.

摘要： A purging system for an engine system is disclosed. The engine system includes an engine and one or more to-be-purged sub-systems. The purging system includes a centralized purging unit with one or more compressed air sources to store and provide compressed air. The compressed air sources are fluidly communicable with each of the to-be-purged sub-systems. A control valve assembly includes one or more valves that are operably positioned between the compressed air sources and the to-be-purged sub-systems. A controller, which is in control communication with the control valve assembly, is configured to alternate the valves between an active state and an inactive state. This is to vary the fluid communication between the compressed air sources and at least one of the to-be-purged sub-systems. This alteration is based on a set of predefined threshold conditions.
