摘要： [0043] The method according to the invention is a method for controlling the purging of a selective catalytic reduction system (1) for a vehicle. The selective catalytic reduction system (1) has a pump (4) for reducing agent (3), at least one supply line (5) supplying reducing agent (3) to an exhaust line (10) of the vehicle, and a purge fluid suction device. The method is characterized in that it involves determining a purge duration as a function of a state of fill of the supply line (5) prior to activation of the purge phase, and in that the method further comprises the updating of the purge duration during purging.

摘要： The invention relates to a method for calculating a guideline for adding a reducer fluid, via an appropriate adding means (5), into an exhaust line of a combustion engine (1). Said method is characterized by the following steps: assessing the pressure in the exhaust line at the point where the reducer fluid is added; assessing the pressure of the reducer fluid at the inlet of the adding means (5); and calculating the adding guideline on the basis of the pressure within the exhaust line and the pressure of the reducer fluid.

摘要： The invention relates to a method for repriming a system for injecting a liquid additive in an exhaust system of a motor having a heat engine, wherein the injection system comprises: a tank for the additive; a hydraulic circuit for conveying said additive to one or more injectors; a pump for pumping the additive contained in said tank; in said hydraulic circuit, a valve positioned over the length of said hydraulic circuit; and an accumulator for said liquid additive on said hydraulic circuit. The invention is characterized in that it includes the steps of: refilling the accumulator with liquid additive; detecting the presence of air in the hydraulic circuit upstream from the accumulator; stopping the refill of liquid additive into the accumulator; depressurizing the hydraulic circuit between the tank and the accumulator; and discharging the air contained in the hydraulic circuit between the tank and the accumulator. The invention is can be used in particular in systems for injecting a mixture of water and urea for vehicles, the engine of which uses diesel fuel.
