Abstract (en)
[origin: WO0068551A1] An engine management system is disclosed for regulating the quantity of fuel supplied to the engine cylinders of an engine fitted with a three-way catalytic converter. The system operates in its normal mode to regulate the air to fuel ratio (AFR) such that emissions of hydrocarbons, carbon monoxide and oxides of nitrogen are minimised by the action of the catalytic converter. The system can also operate in a second mode in which the feed gases to the catalytic converter have excess oxygen. To regenerate the catalyst, the system switches periodically to the second mode of operation and remains in the second mode only for sufficient time to expose up to the entire volume of the catalytic converter to an oxidising environment.
