Commonly mistaken for a fuel additive, Adblue is a fluid used most commonly within the Euro 4&5 engines. It is in fact, so essential to their functionality, they are unable to operate without it.
Adblue is essential for the cleansing and reduction of harmful emissions and is injected into the exhaust gasses cleaning the exhaust gasses before they enter the atmosphere. It is Stored safely within a separate tank on the vehicle, and is specifically measured and applied by spraying into the exhaust manifold, reacting with the gasses within it, creating the cleansing and catalytic effect. Adblue consumption is typically around 3% – 5% of the diesel consumption for a typical vehicle, dependent of loading weight and other relative factors.
Requirement for Public Transport
Since 2006, the use of Adblue has been a fundamental requirement for many types of public transport including bus and trucks produced on or after that date. Dependent on the truck and mileage it is generally acknowledged that a vehicles Adblue stocks will need to be replenished approximately every 10 days. This is based on each vehicle having a 80 –90 litre adblue tank.
This generally equates to around 1000 litres each month for each vehicle and is not required to apply retrospectively, due to the difficulties in applying the requirement to older modes of transport.
There are currently very stringent quality and regulatory standards in place to govern the way Adblue is produced and to ensure that it conforms with government regulations including the DIN70070 and ISO22241 standards.
Importance of Handling & Storage
By upholding and complying with the relevant guidelines Adblue will perform its role to the highest standards but due to nature of the product it is easy to compromise the overall quality. Such things include handling and storage to name the most prevalent types of misuse and it is not uncommon for vehicle manufacturers to fail to support warranties if this type of misuse has occurred.
The two most important things to remember when handling and storing Adblue is the storage temperature, which should never fall below -11°C and secondly to prevent any foreign objects from coming into contact with the solution causing contamination.
To conclude, Adblue is a fundamental resource for many modes of transport and is so important it has been made an essential regulation that requires strict adherence and governance. Due to the nature of the product it is essential to maintain its natural state and not to compromise its condition in any way, particularly those involving changing temperatures and foreign bodies. Handling Adblue requires care and consideration and these measures should not be overlooked under any circumstances.
