Does the Maxus G20 diesel version require urea?

[DiMaria]

The Maxus G20 diesel version requires urea. After filling up with urea, the Maxus G20 diesel vehicle can run for 2,000 to 3,000 kilometers. Urea can last a long time, but if there are any abnormalities, it indicates a system issue that requires immediate inspection. Adding urea to diesel engines: Urea is required for diesel engine vehicles because diesel engines emit harmful nitrogen oxide (NOx) gases, which cause environmental pollution. Long-term inhalation of these exhaust gases can be highly detrimental to human health. To mitigate this harm, vehicles with diesel engines use urea, which has a catalytic function. When it encounters nitrogen oxides, it triggers a chemical reaction, converting them into nitrogen and water before being expelled. Catalytic reduction reaction: Qualified urea solution consists of 32.5% ultra-pure urea and purified water. The vehicle's urea solution reacts with NOx through selective catalytic reduction, converting it into nitrogen, oxygen, and water, thereby reducing nitrogen oxide emissions. This applies to all Euro IV and Euro V emission-standard diesel engine SCR systems.
