BlueHDi ENGINE: EXHAUST GASES TREATMENT

i

AN EXCLUSIVE TECHNOLOGY

/image/06/5/peugeot-308-2015-059-en.343065.jpg

Developed by the PSA Group, BlueHDi technology combines the additive particulate filter (DPF) with SCR (Selective Catalytic Reduction) to treat emissions of nitrogen oxide (NOx) by adding AdBlue®. This technology slashes NOx emissions by up to 90%. The SCR catalyst breaks down the NOx into water vapour (H2O) and nitrogen (N2).

BlueHDi technology is the most efficient on the market in reducing polluting emissions. With this range, PEUGEOT maintains its lead in reducing pollution from diesel engines.
The 1.6L BlueHDi and 2.0L BlueHDi engines are fitted in the PEUGEOT 208, 2008, 308, 308 SW, 3008, 508, 5008, Partner Tepee, Traveller, Partner, Expert, and Boxer.

AdBlue® and SCR technology

To respect the environment without impacting the performance or fuel efficiency of its diesel engines, PEUGEOT has decided to equip its vehicles with a system to break down emissions of nitrogen oxide (NOx) into nitrogen (N2) and water vapour (H2O). This system combines SCR (Selective Catalytic Reduction) with AdBlue® i in order to treat exhaust gases in compliance with the requirements of the new Euro 6 standard.

AdBlue® is a non-flammable, colourless and odourless solution, to be stored in a cool place. It comprises 32.5% of urea, diluted in demineralised water.

AdBlue® is held in a special tank of around 17 litres, for a driving range of around 20,000 km. A warning is sent out automatically as soon as the tank reaches the reserve level: you can then drive for a further 2,400 km or so before the tank runs out.

The AdBlue® tank is accessible from the fuel flap or boot. The AdBlue® is topped up whenever your vehicle is brought into the PEUGEOT network or a qualified workshop for maintenance. Nevertheless, depending on the way you use your car, you may need to top up the level between two maintenance operations, particularly in the event of an alert (indicators and message).
If you intend to top up the level yourself, please read the onboard documentation carefully.

AdBlue® freezes at temperatures below -11°C approximately and deteriorates at temperatures over 25°C. The SCR system includes a function to heat the AdBlue® tank so that you can drive in any weather conditions. The bottles or cans should be stored in a cool place away from direct sunlight. If these conditions are respected, the liquid will keep for at least a year. If the liquid freezes, it can be used after thawing at ambient temperature. The date of manufacture is given on the label of your AdBlue® container. Only use AdBlue® complying with the standard ISO 22241.

When the AdBlue® tank is almost empty (remaining range of around 600 km), you need to take your car to the PEUGEOT network or to a qualified workshop as soon as possible. When the AdBlue® tank is completely empty, a regulatory device will be activated automatically to stop the engine starting. A range indicator tells you how far you can go before the vehicle stops.

Advice for use

  • Don't store AdBlue® bottles or cans in your car.
  • Never top up your tank from an AdBlue® distributor for trucks if the AdBlue® tank filler cap is in the boot of your car.
  • Never transfer AdBlue® to another recipient: it will lose its purity.
  • Never dilute AdBlue® with water.
  • Never pour AdBlue® into the diesel fuel tank, or diesel fuel into the AdBlue® tank. AdBlue® is not an additive so must not be mixed directly with the fuel.
  • If you splash the liquid onto your skin, rinse immediately with cold water or wipe with a damp cloth. If the liquid has crystallised, remove it using a sponge and hot water.

If you make a mistake, don't start the engine. Contact the PEUGEOT network or a qualified workshop.

CONTROLLED EMISSIONS

BlueHDi technology is PEUGEOT'S solution for preserving air quality by fine-tuning combustion and filtering exhaust gases.

The goal is to reduce NOx emissions by 90% while removing 99.9% of fine particles. The SCR (Selective Catalytic Reduction) transforms NOx gases into water vapour and nitrogen by catalytic action.

RECOGNISED EFFICACY

BlueHDi is the only technology that provides rapid priming after starting. In fact, the Selective Catalytic Reduction (SCR) is positioned upstream of the additive particle filter (FAP).

This combination (SCR + additive FAP) is particularly effective in treating exhaust gases.

Always leading the field, PEUGEOT fitted its cars with FAP technology 11 years before it became an industry norm. It was a world first with the PEUGEOT 607 in the year 2000.
