BANS ON DRIVING

NOx reduction systems for Euro 5 diesel vehicles

Driving bans on diesel cars have been in force in German cities such as Hamburg, Stuttgart and Darmstadt for several months. Many more cities and local authorities are in the process of enacting regulations that will soon restrict the use of diesel vehicles, including those compliant with Euro 5.

Widespread driving bans on diesel vehicles are the result of legislation in Germany regulating air-quality standards and peak emissions (39. BImSchV) (39th Federal Emissions Protection Act). This directive is intended to ensure air pollution does not exceed the nitrogen oxide emissions limit of 40 micrograms per cubic metre of ambient air set by the European Union, and is based on local measurements of nitrogen oxide emissions. Cities and communities that exceed the EU limit can resort to a number of measures, including various forms of driving bans on diesel vehicles.

It is possible to completely avoid diesel driving bans in Germany by retrofitting diesel cars with the new Dr Pley by Bosal SCR technology. Suitably retrofitted vehicles are permanently exempt from driving bans from the day of installation. There is no need for a change to the emissions standard, merely an additional mention in the vehicle documentation.

As it currently stands, major vehicle manufacturers are prepared to provide financial support for such retrofitting. For further information, see the websites of the individual manufacturers.

SCR Technology

Protecting the environment

The SCR system developed by Dr Pley SCR Technology GmbH and produced and sold by Bosal Retrofit GmbH is suitable for upgrading the hardware of diesel cars compliant with Euro 5 (SCR stands for Selective Catalyst Reduction). It fulfils all the requirements of the new retrofitting guideline for exemption from driving bans.The system is TÜV tested and certified with a homologation (ABE) from the German Federal Motor Vehicle Authority (KBA).

The SCR system reduces the harmful nitrogen-oxide emissions (NOx) produced by the combustion process in diesel engines using a targeted and precisely timed injection of AdBlue®, a liquid for the aftertreatment of exhaust gases. It reduces the NOx in a car’s exhaust by up to 80 percent, meaning retrofitted diesel vehicles comply with the stipulated maximum figure of 270 micrograms of NOx per cubic metre and can thus be fully exempted from diesel driving bans.

The main part of the retrofit involves the installation of a control unit, an SCR catalyst and hydrolysis device as well as an AdBlue® tank and a number of sensors. The installation takes around three hours at an approved dealer or service centre and costs an average of 3,000 to 3,600 euros. Following successful installation, the retrofit system is certified and added to the vehicle documentation. There is no need for a new environment sticker.

Vehicle Registration and Contact for Approved Service Centres

We are working on making SCR systems available for all vehicle makes and models. However, our range is currently limited to models by Volvo, Mercedes-Benz and BMW and available only via approved service centres.

If you drive a diesel car, you will soon be able to register your interest in a retrofit kit via an online form. We will then check your options and pass your details on to a suitable approved service centre.

Representatives of dealers and service centres can access further information and kit supply details by contacting our Workshop Service team at Bosal Retrofit GmbH in Viersen, Germany.
