Abstract: Disclosed is a heater of a ureaaqueous solution supplying system for a selective catalyst reductor. The disclosed heater of the ureaaqueous solution supplying system for a selective catalyst reductor is mounted on a ureasolution tank which stores a ureaaqueous solution in order to defrost the ureaaqueous solution frozen under a low temperature condition. The heater of the ureaaqueous solution supplying system for a selective catalyst redactor comprises i) a PTC heater mounted inside the ureasolution tank to generate thermal energy by receiving electric power from a battery; ii) a piezoelectric sensor which is electrically connected with the battery and the PTC sensor, senses expansion pressure due to freezing of the ureaaqueous solution, generates electric energy according to the expansion pressure and applies a switching signal between the battery and the PTC heater; and iii) a cut-off sensor which is electrically connected with the PTC heater to cut off electric power applied from the PTC heater by increasing resistance when the temperature of the PTC heater is over the Curie temperature.

Abstract: An air vent structure integrally formed with a filler neck is provided to prevent moisture from being introduced into a canister by forming a water discharge path formed with a water discharge hole along the circular air vent structure. An air vent structure integrally formed with a filler neck comprises an air filter(40) and a vent line(50) connected to the air filter. The air filter is installed at the lower end of the filler neck(10). The vent line is connected with the upper end of the filler neck such that an air discharge port is positioned at the inner side of a filler door. The air discharge port is prepared in the form of a gap between a fuel injection port and a rubber packing, which surrounds the fuel injection port. A plate for fixing the injection port is formed around the fuel injection port. A water discharge path is formed along a circular passage groove of the plate.
