    • PROBLEM TO BE SOLVED: To avoid possibility of injury of a human body such as burn, or fire by lowering a temperature of overheated gas. SOLUTION: An apparatus for cooling overheated gas in an engine room is connected between a diesel engine and an exhaust pipe of the diesel engine, and has a diesel particulate filter preventing particulate substances. The apparatus includes a through-hole provided to penetrate one side of the engine room, a tail pipe, one end of which is connected to the diesel particulate filter, and the other end of which is extended outwardly from the engine room through the through-hole, for discharging outwardly the overheated gas discharged when regenerating the diesel particulate filter, a cooling fan, provided on one side of the engine room, for generating an air stream by sucking ambient air, and a diffuser assembled in the through-hole to enclose the outer circumference of the tail pipe in such a way a space is formed between the diffuser and the tail pipe to prevent the diffuser from directly contacting the tail pipe, and to prevent dispersion of the air stream after sucking the air stream for lowering the temperature of the overheated gas.
