Method for regenerating the oxidation catalyzer of the exhaust gases of an internal combustion engine

摘要

In operation of an internal combustion engine, exhaust gases of the internal combustion engine are directed through an oxidation catalyzer and thereby heat the catalyzer. Subsequently the engine is stopped, and the catalyzer is regenerated by supplying reducing gas to the catalyzer while the catalyzer is still sufficiently hot for regeneration to occur.
