Installation for dispensing a urea-based antipollution additive for automobiles

摘要

The installation has a dispenser including a flexible pipe (10) provided with a dispensing nozzle at its free end to permit transferring of volume of urea based antipollution liquid additive to a specific reservoir of a motor vehicle e.g. lorry. A heating circuit (14) has a heating electric cable (13) that is extended on the entire length of the tube. Control units (15) are associated to a temperature probe to automatically close the circuit when external temperature drops to a preset lower limit i.e. -5 degree Celsius, for reheating the additive contained in the tube.
