Method of controlling emission control for motor vehicle internal combustion engine involves special operating condition with unburnt fuel injected into exhaust gases

摘要

The method of controlling emission regulation in a motor vehicle internal combustion engine involves controlling the temperature of the emissions control (230) dependent on the condition of the control or the engine. The control method can include a special operating condition in two phases. In the special operating condition, unburnt fuel can be injected into the exhaust gases.
