Euro 6 – AdBlue®

ADVANCED EMISSIONS CONTROL FOR DIESEL ENGINES

Auto-Sleepers 2017 motorhome range will feature engines with Selective Catalytic Reduction (SCR) using AdBlue®*, a water/urea based additive which is stored in a tank (like diesel fuel), however, unlike fuel it is not injected into the engine, but directly into a specially modified part of the vehicle’s exhaust. This begins a chemical reaction which removes the polluting oxides of nitrogen (NOx), converting them into harmless oxygen and nitrogen in a process known as Selective Catalytic Reduction, or SCR for short. SCR is only applicable to diesel engines and the more economically you drive, typically, the less AdBlue® you will use.

Generated from a world-famous diesel heritage and innovative, automotive engineering excellence, BlueHDi complies with Euro 6 emission standards to deliver a driving experience rich in power and performance but with exceptional fuel economy and lower CO2 emissions.

Why is this new technology required?
All manufacturers must meet Euro 6.1 requirements for base vehicles built on or after the 1st September 2016. These requirements ensure that vehicles feature the latest and best emission equipment which emits fewer pollutants with aim to reduce effects on the environment.

How does AdBlue® meet the Euro 6 standards?
BlueHDi engines meet Euro 6 standards thanks to Selective Catalytic Reduction (SCR) and Particle Filtration processes. A three stage cleansing process specifically targets the pollutants of diesel combustion, removing hydrocarbons and carbon monoxide, reducing nitrogen oxides by up to 90% and eliminating 99.9% of particulates:

Stage One – the oxidation catalytic converter eliminates the HC and the CO2, transforming them into water (H2O) and carbon dioxide (CO2).

Stage Two – the SCR (Selective Catalytic Reduction) transforms the nitrogen oxides (NOx) into water and nitrogen (N2), which is the main constituent of air (78%), due to the addition of AdBlue® (mixture of urea and water).

Stage Three – the Particulate Emission Filter eliminates 99.9% of the particulates by number.Peugeot Euro 6 Ad Blue Engine Image

What happens if my AdBlue® runs out?
If your AdBlue® runs out, your vehicle will then stop. Under the legislation it is a mandatory requirement that a vehicle cannot be driven under conditions where emissions will not meet the required level. To avoid this keep alert of your UREA warning lights, once there is 1,500 miles left before the tank is empty an orange UREA warning light and audible warning will alert the driver. 350 miles before running out the driver is signalled continuously by the illumination of a red UREA warning light and a service warning light, along with an audible and verbal warning. If the driver continues until the tank is completely empty, when the vehicle is switched off the vehicle will not restart. The average annual motorhome mileage is between 6,000 – 8,000 miles, the AdBlue® tank if full is more than capable of these sorts of distances without the requirement to fill up, also on the annual service the Peugeot dealership will top up your AdBlue® as part of the service. Therefore for the majority of motorhome customers there will be no need to fill up between services. If a top up is required, it can be easily purchased from your Peugeot dealership or most service stations.

Do we have to use a Peugeot specific AdBlue®?
No. There is only one type of AdBlue®, which can easily be purchased if required from either a Peugeot dealership or most fuel stations.

Does AdBlue® reduce the payload of a vehicle?
No. On a boxer base the engine has changed to a 2.0, which is lighter than the Euro 5 engine, therefore there is no difference in base vehicle payload from Euro 5 to Euro 6.

What is the operational cost as a motorhome driver for AdBlue®? 
As the average annual motorhome mileage is relatively low, it is expected that with the majority of customers the AdBlue® will be topped up by the Peugeot dealership at the point of your annual service. However if it is required your Peugeot dealer can top up 10 litres at a fixed price of £9.99.

Is the AdBlue® tank easy to locate and fill?
Yes. The 15-litre tank is accessible from the outside and is located under the fuel filter.

Important Information

  • AdBlue® is not a fuel additive. This is why there is a separate AdBlue® tank
  • If you put AdBlue® in your fuel tank by mistake, please do not start the engine, but contact a retailer for help
  • Put only AdBlue® in the AdBlue® tank; do not fill the AdBlue® tank with any other liquids
  • Prevent anything from contaminating AdBlue®
  • If small quantities of AdBlue® come into contact with the vehicle’s paintwork, for example, wipe them off and if necessary rinse the area with water

* Models built on a Fiat Chassis will not feature SCR using AdBlue®, utilising NOx Trap technology instead.
