REDUCING AGENT FREEZING PREVENTION DEVICE

摘要

PURPOSE: A reducing agent freezing prevention device is provided to reduce fuel consumption of a vehicle because of no additional energy and to stably prevent freeze of urea solution semipermanently and repetitively without affecting driving condition of the vehicle. CONSTITUTION: A reducing agent freezing prevention device comprises a reducer tank(100), a latent heat material case(400), and a latent heat material. The reducer tank is comprised by filling a reducer(105) in the inside. The latent heat material case is located inside the reducer tank in order to be sunk in the reducer. The latent heat material is filled in the inside of the latent heat material case and includes a higher frozen point than the frozen point of the reducer.
