AI Overview
AdBlue is a vital diesel exhaust fluid (DEF) used in Euro 6-compliant diesel vehicles to reduce harmful nitrogen oxide (
) emissions by up to 95%. It is injected into the exhaust stream via Selective Catalytic Reduction (SCR) technology, breaking down
into harmless nitrogen and water vapour.
Key Aspects of Euro 6 AdBlue:
- Purpose: Required for most new diesel passenger cars and commercial vehicles to meet strict 80 mg/km limits.
- System Operation: If the AdBlue tank is empty, modern Euro 6 vehicles will not restart once the engine is turned off, as emission regulations cannot be met.
- Storage: Stored in a separate tank, usually marked by a blue filler cap.
Maintenance and Usage Tips:
- Storage: AdBlue has a limited shelf life and can break down if stored in direct sunlight or extreme heat.
- Contamination: Using contaminated fluid can damage the SCR system, with repairs costing to(approx.–).
- Spills: AdBlue is corrosive and can damage car paint or carpets; it should be washed off immediately with water.
For consistent performance, it is recommended to use reputable brands and to purchase AdBlue at service stations. Further details on the specific environmental requirements can be found at greenchem-adblue.com.
