摘要： Methods and systems are provided for addressing engine cold-start emissions while an exhaust catalyst is activated. In one example, a method for improving exhaust emissions may include flowing ionized air into an engine exhaust, downstream of an exhaust catalyst, to oxidize exhaust emissions left untreated by the catalyst. The approach reduces the PM load of the exhaust as well as of a downstream particulate matter filter.

摘要： It is an object to make it possible to burn and remove particulate matter without generating runaway even if the particulate matter is excessively accumulated at the time of regeneration of an exhaust gas purification device. A common rail engine and the exhaust gas purification device placed in an exhaust gas path of the engine are provided. A plurality of regeneration controls for burning and removing the particulate matter accumulated in the exhaust gas purification device can be executed. The plurality of regeneration controls include at least non-operation regeneration control for rising exhaust gas temperature by combining post injection (E) and predetermined high speed rotation speed, and recovery regeneration control which can be executed when the non-operation regeneration control fails. In the non-operation regeneration control and the recovery regeneration control, the engine is driven exclusively for burning and removing the particulate matter. The recovery regeneration control is carried out at exhaust gas temperature lower than that of the non-operation regeneration control while taking time longer than that of the non-operation regeneration control.

The system may include: an air supply passage adapted to provide for passing air to be supplied to an engine; an exhaust manifold adapted to transmit exhaust gas of the engine to an exhaust passage; an air injection passage adapted to connect the air supply passage with the exhaust manifold so as to supply a part of air passing through the air supply passage to the exhaust manifold; and an air valve disposed at the air injection passage so as to selectively open or close the air injection passage. Unburned gas melded in exhaust gas may be combusted according to air supplied to the exhaust manifold.

摘要： An exhaust treatment system for an engine includes a regeneration device being in receipt of exhaust from the engine and positioned upstream of a diesel particulate filter. A compressor provides a source of compressed air. An air/fuel nozzle is coupled to the regeneration device, in receipt of a fuel supply as well as the compressed air. The fuel and compressed air are forced through an orifice of the nozzle to atomize the fuel. A bypass line provides compressed air from the compressor to the regeneration device without passing through the orifice of the nozzle. A valve is operable to allow compressed air to flow through the bypass line when a predetermined condition exists.

摘要： A method of operating a hybrid vehicle when an internal combustion engine is not running includes heating a flow of air flowing through an exhaust gas treatment system of the internal combustion engine that is supplied by an air pump with a heating module and a hydrocarbon injector. The heating module heats an electrically heated catalyst of the exhaust gas treatment system in preparation for starting the internal combustion engine. Additionally, thermal energy is recovered from the flow of air downstream of the electrically heated catalyst and transferred to at least one other vehicle system to provide thermal energy to the vehicle system, such as an engine coolant for a cabin heating system or a transmission fluid for a drivetrain transmission system.
