Disclosed is a device for injecting ammonia in gaseous form into an exhaust line of a combustion engine, the device including a supervisor, an evaporation chamber incorporating a heater for heating a quantity of reducing agent thus releasing ammonia in gaseous form that exits the evaporation chamber via a pipe opening into the exhaust line. The control supervisor is associated with an internal first pressure sensor housed in the evaporation chamber and with a second pressure sensor intended to be housed in the exhaust line, including a calculator calculating a quantity of ammonia to be injected into the exhaust line at a given instant as a function of the pressure values from the first and second pressure sensors.
