Abstract: Engine exhaust system for an internal combustion engine, the engine exhaust system comprising an exhaust conduit (14) connected to an engine (30), an exhaust gas return conduit (32,33) such that at least a part of the exhaust gas can be returned to the engine. The exhaust gas return conduit, at least along a part of its length, is formed with at least two flow paths (48,49). The engine exhaust system further comprises a particle filter arranged in each of the at least two flow paths and at least one cold flame vaporizer (11) in which fuel is partially oxidized in preheated air to form a cold flame gas. The at least one cold flame vaporizer is arranged in fluid communication with all the flow paths such that the cold flame gas can flow through the particle filters, whereby the cold flame gas can be used to regenerate the particle filter in at least one of the exhaust flow paths while, simultaneously, exhaust gas can flow through the other exhaust flow path or exhaust flow paths. A method for the cleaning of a particle filter is also provided.

Abstract: Exhaust gas apparatus for the cleaning of exhaust gas where the exhaust gas apparatus comprises an exhaust conduit section which is formed with at least two separate flow paths. Each flow path is provided with a particle filter for the removal of particulate matter from the exhaust gas, an NOx trap for the removal of NOx from the exhaust gas. The exhaust gas apparatus further comprises at least one cold flame vaporizer in which fuel is partially oxidized in preheated air to form a cold flame gas where the cold flame vaporizer is arranged in fluid communication with each of the flow paths in the exhaust conduit section such that the cold flame gas can flow through the particle filter and the NOx trap, and valve means for controlling the flow of cold flame gas from the cold flame vaporizer to each flow path in the exhaust conduit section. Thereby, both the particle filter and the NOx trap in at least one of the flow paths can be regenerated in a single operation. There is also provided a method for regenerating cleaning means for exhaust gas where the cleaning means comprises an NOx trap and possibly a particle filter.
