PROCESS FOR STARTING AN SCR SYSTEM |
摘要 |
<p>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.</p> |
