Diesel Exhaust Treatment liquid (for:, automotive environmental urea), SCR technology must be used in consumables. Urea (AUS32 ) is classified as non-dangerous. AUS32 is a transparent liquid with a faint ammonia odor.
If spilled, the water evaporates, forming crystals. Vehicle selective catalytic reduction exhaust aftertreatment (SCR) is a technology that reacts with ammonia and automobile exhaust gas produced by urea reaction, and is a comprehensive emission control system certified to meet European Ⅳ regulations.
is a technology to control NOx in diesel engine exhaust. The AUS32 is stored in a urea tank mounted on the chassis. The urea tank supplies the solution to the dosing unit (DU) installed on the chassis. DU is controlled by the engine control module (ECM). DU uses compressed air from the vehicle system to produce AUS32 sprays, which are transported to the nozzles in the engine exhaust system through very precise metering and pumping systems. The number of AUS32 injected into the exhaust is controlled by the ECM and can be matched to the NOx output of the engine at any speed and load condition. When exposed to high-temperature exhaust, water evaporates rapidly and urea becomes ammonia. Ammonia and NOx in the catalytic converter through high temperature oxidation and reduction reaction to generate nitrogen and water, the system can effectively reduce the amount of nitrogen and oxygen compounds in automobile exhaust gas, reduce the air pollution caused by NOx. Do not allow urea to enter the eye when replacing urea. If the splash can be washed with water. Try not to wait until the environmental protection Urea Light instrument panel Alarm is more note, otherwise, you also need to input urea filling capacity to match.
Environmentally friendly urea is valid for two years and must be replaced when it expires.
