Reduce Bus & Coach emissions with Euro 6 retrofit upgrades
HJS Emission Technology are providing a valuable contribution to air quality improvements in towns and cities across the UK through the use of retrofit SCRT® Exhaust Technology.
Retrofitting with our HJS SCRT System
To reduce emissions, the HJS SCRT® system can be retrofitted to a large range of vehicle applications enabling operators to retrofit older vehicles to meet Euro 6 emission standards. Vehicles in compliance with these standards can travel freely within the Clean Air Zones and Low Emission Zones being introduced throughout the UK and the Ultra Low Emission Zone in London. Non-compliant vehicles may be required to pay daily charges in order to access these zones.
The SCRT® system combines a diesel particulate filter with an SCR unit for the reduction of nitrogen oxides. New buses that are already fitted with particulate filters can be retrofitted with an SCR unit to create an SCRT® system. Likewise, older vehicles without an exhaust treatment system can be retrofitted with an SCRT® system. SCRT® is currently the most advanced and effective exhaust gas aftertreatment technology available.
With the aid of an HJS filter soot particles can be filtered from diesel exhaust gases down to the limit of detection. It’s not just particulate matter that pollutes the environment and damages people’s health: gaseous substances such as Nitrogen Oxides are also harmful. In order to reduce the levels of these gases, HJS has contributed to the development of the SCRT® (Selective Catalytic Reduction Technology) system over the last 25 years.

- Over 95% reduction of gaseous pollutants (CO / HC)
- Low maintenance and cost effective
- Live system performance monitoring via the HJS telematics system
HJS Telematics Module – Aftertreatment Connectivity 4.0
System operating information is logged at a frequency of 1Hz to 1,000Hz by the HJS telematics unit. All recorded data is then stored as a file which is then uploaded to the Cloud system every 2 to 10 minutes ensuring that the most recent data is available to view.
If the mobile network connection is temporarily unavailable, the telematics system will buffer the data until the data network connection is restored and data re-transmission will occur.
Where predetermined system operating limits are breached or if system servicing is required, text message and email alerts can be created.
