    Abstract: A tank for storing an internal combustion engine exhaust gas liquid additive, the tank including a wall defining an internal volume, an electrical component located in the internal volume, and at least one electric cable configured to connect the electrical component to a voltage source outside the tank, at least one portion of the electric cable being inserted into an intermediate part connected to a base plate mounted over an opening in the wall, the base plate incorporating a casing mounted leaktight around an orifice in the base plate. The intermediate part is fastened by a quick-connect coupling including an electrical connector to which the electric cable is connected leaktight with aid of a seal and that emerges from the orifice in the base plate to outside the tank. The seal is inserted between the intermediate part and the connector and/or into a housing of the intermediate part.

    Abstract: Process for starting an SCR system intended for transporting urea from a tank to the exhaust gases of an engine using a feed line, this system comprising a rotary pump controlled by a controller and driven by a brushless direct current (BLDC) motor that comprises a rotor equipped with at least one permanent magnet and with a stator comprising at least 3 electromagnetic coils in which the direct current can flow according to a given sequence to make the rotor rotate, according to which, before starting the pump, a temperature is measured using a sensor and if this temperature is below a setpoint temperature, before making the rotor rotate, the current is passed through at least one of the coils in a way such that it preheats the pump without making the rotor rotate.
