Spark-ignited internal combustion engine oxide gas absorbing arrangement and method |
摘要 |
In the embodiments described in the specification, a spark-ignited internal combustion engine has an exhaust line containing an oxide gas absorber for absorbing NOx and SOx and desorbing NOx and SOx at elevated temperatures. The support member for the oxide gas absorber is a metal foil or a thin walled ceramic support to permit rapid heating and is coated with a layer of a gas absorbing material at least 50 microns thick to permit longer intervals between regeneration, thereby providing effective storage of oxide gases even with fuel consumption-optimized engines. |
