Methods and systems are provided for an exhaust gas treatment device. In one example, the exhaust gas treatment device comprises an electrochemical cell having a first electrode, a second electrode and an electrolyte provided between the first and second electrodes, wherein the electrochemical cell is configured to convert a first pollutant species, such as nitric oxide, within the exhaust gas to a second pollutant species, such as nitrogen dioxide, such that a concentration of the second pollutant species within the exhaust gases leaving the exhaust gas treatment device is increased relative to the exhaust gases entering the exhaust gas treatment device.

Methods and systems are provided for varying the volume of an engine intake system to increase the volumetric efficiency of the engine. In one example, a resonance system may be coupled to the engine intake system and a position of a movable element in the resonance system may be varied to vary the volume of the chamber in accordance with engine speed. The intake system provides improved volumetric efficiency for the engine.

A method of operating a diesel enginehaving LNTand SCRaftertreatment devices arranged in series to receive exhaust gas from the engine is disclosed in which the engine is operated in a rich early injection mode to generate ammonia in the LNT for storage in the SCR located downstream from the LNT. This reduces the amount of soot produced permitting longer operation of the engine in rich early injection mode and further may reduce the use of PGM material in the LNT and increase the amount of ammonia for use in the SCR.
