DIESEL – into a clean future

HJS at bauma 2016

Diesel emissions with their NOx- and soot contaminations, especially in our inner cities, are a serious danger to the health of everyone who lives and works there. Only recently, repeated particulate matter alarms in the southern German city of Stuttgart triggered a fierce response, because society's sensitivity to the issue of sustainable environmental protection has grown and continues to grow worldwide.

The diesel-emissions bombshell that has befallen the automotive industry over the past months clearly highlights the potential impact. Without doubt, the entire diesel industry is going to have to take a long, hard look at itself: The standing of diesel is at stake. Diesel based powertrains have to fulfil ever stricter emissions regulations – consequent and sustainably.

"Despite all this, there's practically no real alternative to the diesel engine, particularly in respect of many applications in the commercial vehicles and industrial engines segment", emphasizes Stefan Lefarth, HJS's man responsible for Business Development. "All the more important is it, then, to find technologically sound answers to the challenges posed by legislation. The ongoing globalisation of the markets, each with its own specific parameters, such as fuel quality, makes the situation all the more difficult. Alternative fuels, such as CNG and LPG, are playing an increasingly important role in many segments, both commercially and ecologically."

It's in this area of friction that HJS has become one of the leading comprehensive exhaust system specialists and, thanks to 40 years of experience and its broad product portfolio, is now better positioned than ever before. OEMs all around the world trust in HJS's development and production expertise:

  • End-to-end, turnkey exhaust-system solutions, including development, OBD and certification
  • Upgrading of existing Stage IIIA engines with standalone exhaust systems to Stage IV, already prepared for Stage V compliance thanks to the integration of SMF® particulate filters
  • Sulphur-resistant filter technologies for emerging markets
  • Technologies for diesel, petrol and gas-powered engines

Furthermore, in Germany, the first local authorities and private organisations are already introducing emissions limits for inner-city and urban areas and, step by step, the compulsory fitting of particulate filters in construction machinery. Berlin, Bremen and Baden-Württemberg are the first German states to have laid down binding environmental standards that should lead to a significant improvement in air quality. Companies must respond because the awarding of future public contracts will in many cases be conditional upon the use of only construction machines that are equipped with a built-in PM filter.

"The task of upgrading older vehicle fleets in line with current emissions standards is one that will take many a year. In addition, not all Stage IV construction machines are equipped with particulate filters. What's needed are cost-effective and, above all, easy-to-apply retrofit concepts, such as our SMF®-ER system with external cleaning", adds Axel Middendorf, Head of Retrofit at HJS. "This system stands out thanks to the ease with which it can be mounted, dismantled and reinstalled on the machine by means of quick-action clips."

As a result of the discussions on this topic being held in the public domain, industry and manufacturers find themselves under ever increasing pressure to act. HJS offers an established product portfolio comprising autarkic and robust retrofit systems:

  • Affordable particulate filters from HJS's modular range of retrofit products
  • SCR & SCRT systems, including all peripherals
  • SMF®-AR particulate filters with active regeneration
  • Innovative SMF®-ER replaceable filters

From 11 to 17 April 2016, the HJS Team will be ready and waiting to answer questions and provide information on any aspect to do with emissions treatment systems. You can find us at bauma 2016 in Hall A5 on Stand 203.

About HJS:

HJS Emission Technology GmbH & Co. KG is a medium-sized company founded in 1976 and based in Menden in central Germany. HJS has many years of experience and expertise in the field of exhaust-gas aftertreatment. Some 450 employees are engaged in the development, production and marketing of modular systems for reducing pollutant emissions. These innovative environmental protection technologies can be used either as original equipment or for retrofitting in passenger cars, commercial vehicles as well as in a wide range of non-road mobile machinery and stationary applications. In addition to systems for spark-ignition engines, HJS today focuses on solutions for diesel engines – especially solutions for reducing the emissions of soot particles (particulate matter, PM) and nitrogen oxides (NOx). With its extensive portfolio of patents for DPF® (diesel particulate filter) and SCRT® (Selective Catalytic Reduction Technology) systems, and cooperation with Germany's TÜV certification agency as well, HJS sets benchmarks internationally.
