Що таке AdBlue ⁉️ Для чого потрібна система SCR в дизельних двигунах⁉️

🚙 AdBlue is a liquid for neutralizing nitrogen oxide emissions in the exhaust gases of diesel engines. Typically, such a system for selective neutralization of harmful emissions of diesel engines (SCR) is installed on trucks due to the high amount of diesel fuel consumption and a significant concentration of nitrogen oxide in the exhaust. 🔄 Getting into the exhaust gas stream, urea reacts with nitrogen oxide and breaks it down into water and nitrogen. At the same time, it does not affect the amount of soot in the particulate filter! 🚛 But recently the SCR system has also been installed on passenger cars. The fact is that the concentration of nitrogen oxide increases sharply with increasing efficiency of a diesel engine. This dependence is not linear and increases sharply with increasing efficiency, and therefore power. That is why the SCR system is very often found in diesel engines where maximum power is squeezed out. 👉🏻 A banal example: VW Passat with a 150 hp engine. does not have an ADBLUE system, and the Passat with 190 and 240 hp is already 100% equipped with a nitrogen oxide neutralizer. ⚠️ The ADBLUE system includes ⚠️ Heated tank Feed pump Spray nozzle SCR catalyst where neutralization occurs 🥶The crystallization temperature, conversion to gel, is -11.5, and for complete freezing, a car with an ADBLUE system must stand for two days in the cold at -35. The liquid does not expand like water, so it cannot rupture the tank. After defrosting, AdBlue has the same properties as before freezing. ⛽️ AdBlue consumption is up to 3-5% of the consumption of diesel fuel or 1-3 liters per 1000 km. More in the city, less on the highway. Long-term driving without ADBLUE fluid can disable the catalyst itself. It is not recommended to drive a car with a faulty ADBLUE system for more than 50 hours. 📝 In order not to prematurely disable the ADBLUE supply system, you need to monitor the purity and quality of the liquid that is poured into the tank. It is highly recommended to use only original urea from the car manufacturer. ☢️ You need to be careful with ADBLUE liquid, because it causes accelerated corrosion of iron, aluminum and copper. And if it happens that it spills, you need to rinse it with water as soon as possible and wipe it dry.
