This is achieved by burning off the excess hydrocarbons which result from the extra-rich mixture required for a cold start. Slightly lean of stoichiometric, the exhaust gases from the engine contain excess oxygen, the production of NOx by the engine increases, and the efficiency of the catalyst at reducing NOx falls off rapidly.
