Menden, September 2017 – buses are on the move throughout the entire city, however, are not always clean. In order to lower the nitrogen oxide output, the Federal Government has issued a billion fund. An SCR retrofit is an ecologically appropriate and economically clever solution. With HJS technology, nitrogen oxide pollutants can be removed almost completely from the diesel exhaust gases.

- Technically autonomous system, available immediately
- The system has proved itself as highly efficient in real-life operation (RDE)
Dieselgate, contract violation process of the EU against Germany and complaints from environmental associations because of massive emission contamination – the negative headlines about diesel do not relent. In order to avoid driving bans, the Federal Government wants to invest a billion Euro in the fight of municipalities against nitrogen oxide pollution. One key to a clean future here is the retrofitting of diesel operated commercial and municipal vehicles, and particularly buses used in public transport, with a SCR system. Just how economically attractive and ecologically effective a retrofit with such an autonomous system is will be shown at “Busworld” in the Kortrijk Belgium (20th to 25th October 2017).
In addition, the Federal Government decided at the beginning of September to increase the funds for the retrofit of communal vehicle fleets. Particularly cities are being affected by increased nitrogen oxide pollution.
Functioning pollutant reduction
The modular system developed by HJS removes the harmful nitrogen oxide pollutants (NOx) from the diesel exhaust gases almost completely. The optimisation of the exhaust gas treatment for intra-urban operation and the employment of state-of-the-art technologies makes a significant difference here. In real-life operation (RDE), the HJS systems prove highly efficient and reliable and are available immediately. The retrofit of public transport buses is an especially effective means, because public buses are driving the entire day throughout the city. In addition: Faced with further threats of driving bans, an even greater importance will be attached to public transport in future. Therefore the cities are requested to use vehicles which are as clean as possible and correspond to the current state of exhaust gas technology.
Considered economically, over 40 existing buses can be retrofitted for the price of the new purchase of an electric bus. Over 80 percent of the public service buses in Germany do not yet correspond to exhaust gas standard Euro VI – a retrofit with SCR is absolutely possible. In particular, vehicles of emission standards Euro IV / V / EEV are on offer. In real-life operation the NOx emissions can be reduced by up to 95 percent.
With retrofitting in public local transport, there are already interesting pilot projects ongoing on a European level. Cities such as Berlin, Madrid or London are already demanding clean buses – and with that a cleaner future for their inner cities. Forerunner in Germany is the capital with the Berlin Passenger Transport companies (BVG). In particular, London has already applied many measures for the improvement of air quality. Here more than 1,000 HJS systems were supplied and installed.
Due to the good results experienced in London, in the next two to three years an additional 5,000 buses will be retrofitted with SCR systems for nitrogen oxide reduction. Here the competence of the exhaust gas specialist from South-Westphalia has been expressed in “Made in Germany”: HJS is included among those providers selected, whose technology has been approved by the London Transport Authority (TfL – Transport for London). For this, the British government is currently financing a promotion with approximately 78 million British Pounds in total (an equivalent of over 89 million Euro).
Monitoring of the exhaust gas values
The equipping of city buses with the so-called TV NOx monitoring is a further plus. As a result of remote interrogation, the emissions of the bus can be displayed at any time and in real time with a telematics App. For this, the collated data is provided in a Cloud for calling up for every bus.
The retrofit of thousands of city buses with effective technologies is a milestone for a low-pollutant future. There is detailed information on the technology for public local transport available at “Busworld”, dated 20th to 25 October 2017, in Kortrijk, Belgium. The HJS stand is in Hall 8, Stand 870.
