What to Do If Urea is Added to the Diesel Tank?
1 Answers
Diesel engines are equipped with a fuel-water separator; periodically drain more water from the fuel-water separator. The urea pump transports urea solution to the nozzle via a delivery pipeline. Diesel fuel, along with carbon soot in the exhaust, can gradually clog the after-treatment system. Urea solution undergoes a redox reaction with NOx, forming harmless N2. Diesel fuel may combust or even explode inside the exhaust pipe. It is recommended to immediately clean the urea tank and exhaust pipe. If the vehicle has been operated after adding diesel, the catalyst carrier in the after-treatment system may already be damaged.
