STRUCTURE OF CONTAINER FOR REDUCING AGENT

摘要

A structure of a container for a reducing agent, characterized in that a heat exchanger for the heat exchange between a heating medium using an engine as a heat source (a cooling water for the engine) and a liquid reducing agent and a strainer for the removal of a foreigner in the liquid reducing agent by filtration are provided on the ceiling plate of the body of the container, wherein a suction tube for sucking the liquid reducing agent from the inside of the body of the container is connected to the strainer and a supply port for a liquid reducing agent being freed of a foreigner by filtration is formed. The above structure prevents the whole of the strainer from being exposed to the outdoor atmosphere, especially to the running wind, and thus can inhibit the freezing of the liquid reducing agent present therein, which results in the inhibition of the freezing of an aqueous urea solution and in the achievement of the effective filtration thereof even in a cold district.
