Urea Tank Assembly
Mitsubishi FUSO®

The Urea Tank Assembly, also known as the Diesel Exhaust Fluid (DEF) Tank, is a critical component in modern commercial trucks. This part is responsible for storing and supplying the DEF fluid to the Selective Catalytic Reduction (SCR) system. The SCR system reduces harmful emissions by converting nitrogen oxides into harmless nitrogen and water vapor. The Urea Tank Assembly is made up of several components, including the tank itself, a level sensor, a heating element, and a pump. The level sensor ensures that the tank is always filled to the appropriate level, while the heating element prevents the DEF fluid from freezing in cold temperatures. The pump then delivers the DEF fluid to the SCR system, where it is mixed with exhaust gases and converted into harmless emissions. Overall, the Urea Tank Assembly is a crucial part of any modern commercial truck, ensuring that it meets emissions regulations and operates efficiently.
