As the world becomes increasingly concerned about environmental pollution, the use of automotive urea has gained widespread attention. Automotive urea, also known as diesel exhaust fluid (DEF), is a solution that helps reduce the emissions of nitrogen oxides (NOx) from diesel engines. However, there are specific rules for the use of automotive urea in different regions across the world, including China, Europe, and America.
In China, the use of automotive urea is mandatory for commercial vehicles. The government has set strict rules for the use of this substance, and any vehicle found without it can face serious penalties. The urea solution must be of a certain quality, and the vehicle must be equipped with a urea tank and a system for injecting it into the exhaust.
RULES FOR THE USE OF AUTOMOTIVE UREA
When cleaning urea related accessories, pure water must be used for flushing, and tap water is not allowed;
Carbon steel, galvanized carbon steel, and cast iron materials shall not be used for contact with urea;
Metals or alloys that cannot be contacted by urea: copper, bronze, lead, zinc, aluminum, aluminum alloy, magnesium, magnesium alloy, solder (containing lead), tin;
During transportation and storage, avoid light and high temperatures. When the transportation and storage temperatures are between - 5 ℃ and 25 ℃, and below - 5 ℃, insulation measures should be taken, and when the temperature is above 25 ℃, it should be cooled;
To avoid volatilization and hydrolysis of vehicle urea solution, it should be stored in an airtight and dark place, avoiding direct sunlight
If the inferior urea is used, the SCR system will not work properly. The urea is easy to crystallize, block the SCR nozzle, and the exhaust gas conversion rate is low.
At last , if you are using automotive urea, it is important to follow the rules and guidelines set by your government. This will help ensure that your vehicle is running efficiently and that you are doing your part to reduce harmful emissions.
