Upgrade for a greener urban transportation and reduce Taxi emissions
Urban mobility is essential, but taxi fleets can face challenges in meeting stricter emission standards. HJS UK provides innovative clean air technology specifically designed to reduce taxi emissions.
Our solutions help you achieve compliance with NOx reduction targets, improve air quality, and contribute to a healthier urban environment.
Euro 5 to Euro 6 taxi emission upgrade
Explore how HJS UK can reduce your taxi fleet’s emissions and position you as a leader in sustainable urban transportation.
Convert Taxis to Euro 6 with HJS Retrofit SCR Technology and reduce emissions
- HJS Emission Technology have developed a range of retrofit Selective Catalytic Reduction (SCR) exhaust systems that enable drivers of Euro 5 diesel taxis to upgrade to Euro 6 emission standards.
- HJS retrofit conversions are currently available for the Euro 5 LTi TX4, the Mercedes Vito and Peugeot E7 taxis. All systems have been tested and approved by the Clean Vehicle Retrofit Accreditation Scheme (CVRAS) which is managed by the Energy Saving Trust.
- HJS Selective Catalytic Reduction (SCR) is an advanced active emissions control system that can reduce exhaust tailpipe emissions of nitrogen oxides (NOx) by over 90%.
- The HJS SCR system operates in conjunction with the vehicles existing DPF which already meets the requirements for the reduction of Particulate Matter. The SCR system supplied by HJS consists of an underfloor catalyst, an Adblue tank with airless pump, a variety of sensors and an independent control unit with driver information display.
- The SCR system operates by injecting Adblue (an Ammonia based solution) directly into the exhaust gas stream. The Adblue is mixed with the dirty exhaust gases and passes over the SCR catalyst converting Nitrogen Dioxide emissions into mainly water and Nitrogen.
- SCR retrofit systems have already helped many drivers across the UK to comply with Local Authority Clean Air Zone requirements and avoid the daily access charges. In many cases, government grant funding has been made available to support the taxi trade to upgrade their vehicles.
- Retrofitting existing taxis to meet Euro 6 emission standards is a highly cost-effective way for drivers to avoid the daily access charges and can also give the vehicle a longer life span and can increase its value. It will also help drivers to reduce their environmental impact and contribute to local air quality improvements.
- The SCR system is manufactured in Germany to the highest standard and can normally be installed within one day.

Our systems utilises a two-light dashboard display for clear and immediate status checks. A yellow light indicates a Malfunction Indicator Lamp (MIL) requiring attention, while a blue light reminds you when to refill AdBlue®.
- Electrical diagnosis of all actuators and sensors
- Further diagnosis functions (depending on system scope)
- System status and error messages
- AdBlue level
- Warning light for Adblue level below certain limit
- MIL activation for poor adblue quality is out of range, error message to ECU possible if requested
