Diesel exhaust fluid
What is AdBlue
AdBlue is a diesel exhaust fluid used in vehicles with Selective Catalytic Reduction (SCR) technology To reduce harmful gases being released into the atmosphere.
AdBlue is a 32,5 % solution of high-purity,
synthetically manufactured urea in de-mineralized water.
It is a safe-to-use fluid.
HJ OIL AdBlue product is certified according To ISO 22241 (ISO 22241-1, ISO 22241-2, ISO 22241-3).
This international standard protects your vehicle from contamination which could cause serious damage. Using a urea solution of incorrect or low quality that does not follow these standards risks costly repairs.
Since 2005, HJ OIL has been a pioneer in this market. We have worked alongside and guided hundreds of retailers, distributors and fleets of all sizes in their choice of AdBlue and AdBlue equipment.
To find your nearest contact we have dedicated AdBlue Sales Teams in most countries.
How AdBlue works diagram
Vehicles with SCR technology have a separate tank filled with AdBlue.
This is then injected into the exhaust pipe, in front of the SCR catalyst, downstream of the engine.
Heated in the exhaust, it decomposes into ammonia and CO₂.
When the NOx from the engine exhaust reacts inside the catalyst with the ammonia, the harmful NOx molecules in the exhaust are converted to harmless nitrogen and water, which are released from the tail pipe as steam.
