METHOD FOR TREATING POLLUTANTS USING A THREE-WAY CATALYST WHEN STARTING UP A COMBUSTION ENGINE

The invention relates to a method involving the treatment of the pollutants emitted by a vehicle having a heat engine, in which catalyst means (3) are heated, characterised in that the amount of oxygen (OS) in the catalyst means (3) is controlled to be over a minimum amount of oxygen (OS1) by inject...
