When nitrogen oxides are found in the exhaust pipe, the urea tank automatically sprays diesel exhaust treatment liquid(DEF). The diesel exhaust treatment liquid and nitrogen oxides undergo oxidation-reduction reactions in the SCR catalytic reaction tank to generate pollution-free nitrogen and water vapor for discharge. DEF pumps are used to dispense DEF. These are usually adjacent to fuel pumps so the driver can fill both tanks without moving the truck.
