METHOD FOR CONTROLLING THE OPERATION OF A CATALYTIC NEUTRALIZER-STORAGE OF NITROGEN OXIDES ON A VEHICLE TAKING INTO ACCOUNT REGIONAL FUEL QUALITY

摘要

1. A method for controlling the operation of a catalytic converter-storage of nitrogen oxides on a vehicle that is equipped with a lean-burn gasoline engine or diesel engine and has an electronic engine control system, as well as a navigation system, taking into account the regional quality of the fuel, characterized in that the electronic the engine management system, in the case when the navigation system determines that the vehicle is in a region where fuel with a high sulfur content is used, in the case of a lean-burn gasoline engine, it switches it to operation on a stoichiometric fuel mixture or, respectively, in the case of diesel engine does not allow initiation of the automatic process of removing sulfur from the catalytic converter-storage of nitrogen oxides. ! 2. The method according to claim 1, characterized in that the lean-burn gasoline engine is switched to the stoichiometric combustion mode; accordingly, in the case of a diesel engine, it is not allowed to initiate the automatic process of removing sulfur from the catalytic converter-storage of nitrogen oxides only after how after a vehicle enters a region where fuel with a high sulfur content is used, the fuel in the tank will be completely consumed and the vehicle will need to be refueled. ! 3. The method according to claim 1, characterized in that the engine control system switches it back to normal operation only after the vehicle enters the region in which
