Diesels in conurbations: ban or improve? HJS Emission Technology to use IAA 2016 to launch solutions to cut commercial vehicle emissions in urban traffic.

22/08/2016 - HJS

Hanover/Menden – July 2016: Dieselgate, EU infringement proceedings, a flood of lawsuits against local authorities due to massive immission levels – the stream of negative headlines concerning "diesel pollutant emissions" has been constant for months. For although it's clear that diesel exhaust fumes – with their NOx and particulate loads – pose a serious danger to the health particularly of people who live and work in conurbations and inner-city areas, the critical limits laid down are still being greatly exceeded in many places. The consequence of this is that the reputation of diesel is at stake!

For Dr Markus Müller, HJS Emission Technology's board member responsible for development, production and sales, the task is clear: "More and more people are living in cities and large urban centres. This future living environment requires mobility and logistics, while industry and the whole economy demand a good infrastructure in order to secure jobs. Even if in future the internal combustion engine is destined to play an increasingly less significant role in passenger cars, there's as good as no real alternative to diesel or gas-powered engines in respect of many applications in the commercial vehicles segment." This is why technically legitimate and economically viable solutions to make emissions as clean as possible and improve people's quality of life are so important. HJS, a specialist in vehicle emissions treatment systems for 40 years, will be presenting such solutions at this year's IAA Commercial Vehicles, the 66th edition of this trade fair, which is being held between 22 and 29 September in Hanover, Germany.

Under the slogan "Into a clean future – as good as PM- and NOx-free city driving", the key focus of the company's presence at this world-leading exhibition is its SCR systems developed in-house. These SCR systems and their technology that has been optimised specifically for the low-load conditions typical in urban traffic reduce diesel engines' emissions of nitrogen oxides – which pollute the environment and damage people's health – by more than 90 per cent. The combination of SCR system with HJS's sintered metal filter (SMF) creates what is known as the SCRT® system, which reduces the levels of almost all pollutants found in diesel exhaust emissions. "Many relatively modern vehicles that fulfil the Euro V emissions standard are only fitted with SCR or a particulate filter, but not both. At this year's IAA, we want to show that our emissions reduction solutions can be used to optimise all vehicles operating in our inner cities so that they are genuinely green when on the road", explains Dr Müller.

And this is something that is becoming increasingly significant to the commercial vehicles segment, because goods and delivery vehicles in particular are growing in importance thanks to the good state of the economy and booming internet trade. This was also recently made clear by the President of the German Association of the Automotive Industry (VDA), Matthias Wissmann: "Commercial vehicles are the driving force of our economy", said Wissmann. "In use every day, they play a massive part towards safeguarding our prosperity. No other means of transport is as flexible."

Environmentally friendly vehicles are also of huge importance to city and local authorities. Some 29 German local authorities are currently the subject of infringement proceedings initiated by the European Union due to the statutory immissions limits being exceeded in their area. In future, then, we can expect even stricter limits as well as the introduction of new low emission zones. "This will affect fleet operators and public transport companies in particular", says Axel Middendorf, the man in charge of HJS's retrofit business. "It is absolutely essential to parcel services, tradespeople and inner-city bus operators, but also to local authorities and long-distance hauliers, that they are able to move freely around cities and conurbations. But in future this will presumably only be possible if their vehicles are kitted out with the very best in emissions reduction technology."

Operators, therefore, see themselves under more and more pressure to act, and they will have to modernise their fleets in order to meet the immission levels required. In many cases, it's simply not economically viable to replace vehicles. The process of replacing all fleets with the very latest in Euro VI vehicles will take years. For this reason, in addition to its OEM products, HJS has an established portfolio of highly efficient retrofit systems.

The sales team of HJS Emission Technology will be offering any amount of information on technically efficient and economically viable solutions to the immissions problem at the 66th IAA Commercial Vehicles fair in Hanover (Hall 13, Stand B44) between 22 and 29 September.
