    Urea-SCR system is a high-effective NOx reduction technology in diesel vehicles. Urea injectors typically are installed on the vehicle's exhaust pipe. While the operating temperature of solenoid-type injector is 50℃, the exhaust gas temperature is higher than the temperature of the injector, and it will cause the overheating problem in the injector. Thus, in order to solve the problem, the cooling jacket (cooling system) is required to maintain the operating temperature of solenoid-type injector. In the paper, it was studied about the cooling performance of injector used in the heavy-duty commercial vehicles. First, the cooling performance by air was evaluated through the engine testing, and ESC and ETC mode are used for engine testing. Second, the cooling performance by water was evaluated through the CFD analysis. Therefore, through this study, we should select a more effective cooling system of the solenoid-type injector
