FIELD: transport.
SUBSTANCE: proposed method consists in selective catalytic recovery (in catalyst) of off-gases by reducing agent to be injected into exhaust system. Said method comprises the following stages starting from the vehicle motion beginning. Defining initial distance to be covered to next maintenance. Defining actual distance covered after the last motion beginning. Defining amount of reducing agent used after the last motion beginning. Defining the factor of aggressive driving depending upon said amount. Correcting actual distance covered depending upon aforesaid factor to obtain the distance smoothly covered. Finally, it includes upgrading of corrected distance to be covered to next maintenance depending on smoothly covered distance.
EFFECT: limited use of reducing agent.
