The Euro 6\nemission standards introduced in September 2014 require that oxides of nitrogen\n(NOx) emissions be cut by more than 50% when compared to previous levels. This\nis intended to decrease the pollutants released by diesel exhaust gases and to\ndiminish their environmental impact. As a result, a growing number of vehicle\nmanufacturers are choosing Selective Catalyst Reduction (SCR) exhaust\nafter-treatment that uses AdBlue\u00ae.<\/p>\n\n\n\n

What is AdBlue\u00ae?<\/strong><\/h2>\n\n\n\n

AdBlue\u00ae is the commercial name for this aqueous urea solution. It is\nstored in a tank situated in the vehicle and varies in size ranging from 8 \u2013 24\nlitres. The fluid is dosed into the hot exhaust gases using a pump and an\ninjector situated just before the SCR. The fluid enters the exhaust stream and\na reaction occurs by means of thermolysis and hydrolysis in the SCR. The\nnitrogen oxides are then converted into harmless nitrogen and water.<\/p>\n\n\n\n

A mid-size diesel car\u2019s consumption\nof this fluid lasts for approximately 10,000 to 20,000 kilometres between fill\nups. This makes this more of a consumable item than a service item. The need to\ntop up AdBlue\u00ae levels may be\nquite frequent for high mileage drivers and subject to driving conditions.<\/p>\n\n\n\n

Useful Information<\/strong><\/h2>\n\n\n\n

The vehicle has a low fluid level\nwarning system fitted; this is intended to tell the driver that they need to\ntop up their AdBlue\u00ae tank. Failure to\nadhere to the multiple visual and audible warnings can result in the vehicle\nbeing unable to start after it has run out. The car will not start until the\nfluid tank is refilled and may need resetting with diagnostic equipment. <\/p>\n\n\n\n

Euro 5 and Euro 6 exhaust gas\nlegislation requires that the vehicle is prevented from being restarted if an\nadditional reaction agent is used for exhaust gas after-treatment, if there is\na risk of the urea solution running out, or when certain system errors occur. <\/p>\n\n\n\n

It is recommended that drivers should\npay attention to their vehicle\u2019s AdBlue\u00ae level and\nimmediately fill up once a dashboard warning appears.<\/p>\n
