Selective Catalytic Reduction (SCR)
If you’re using a modern Euro 6 diesel engine, the exhaust fumes are then sent to the SCR system to remove harmful emissions with the use of diesel exhaust fluid (AUS 32, commonly called AdBlue).In the SCR system, the SCR catalyst mixes exhaust fumes with AdBlue diesel engine fluid, resulting in the NOx particles being reduced to NH3 (ammonia) and water being expelled from the exhaust valve.
Because the exhaust fluid is added inside the diesel system, it is essential to use AdBlue that meets ISO 22241 specifications to avoid harming your engine with rogue particles. Crown Oil supplies AdBlue® across the UK for a wide range of customers.
