Emission Technology
For reduction of the particle emissions of combustion engines, HJS has been developing and producing application-optimised filter systems since the 1990s. There are HJS products available for cars and commercial vehicles, but also for industrial engines and off-highway applications. In this case, as well as market standard ceramics, HJS also uses in-house sintered metal technology. HJS offers solutions for original equipment, for retrofitting existing vehicles as well as for the spare parts trade.

It is vital that the correct diesel particulate filter system (DPF) is selected for short term use. These applications can be retrofitted with the HJS SMF® ER system in order to remove harmful soot particles from the exhaust. The SMF® ER system is characterised by its easy installation and removal from the machine thanks to its quick release clamps. The SMF® ER offers several advantages to machine operators as it provides an economical solution for equipping an entire fleet of similar construction machines. HJS provides a range of baseplates that can be installed to each machine of equipment which enables a single filter to be used across a range of machines. The regeneration requirements of the filter are displayed via a simple to read gauge and the filter can be removed and cleaned on the operator’s site.
Technology and functioning method
After connection of the flexible hose to the existing exhaust gas system, the exhaust gas is filtered in on-going operation for so long until the limit value is reached, as indicated by the attached pressure gauge. The filter module is pulled out by opening the quick-action locks and cleaned externally. As a result of the modular structure, the system can be mounted or replaced simply on every machine.

HJS filter systems are based on filter modules which are manufactured from ceramic materials. They are often used where no large ash quantities occur. These filter systems can generally replace the original acoustic damper in the area of retrofitting and can be adapted individually to the machines and to stationary applications.
These filter systems require no additional regeneration aids, additives or interventions in the engine management. Over the HJS service unit, the respective operating state and cleaning requirement of the filter system can be read off at any time.
The HJS ceramic filter system is also mainly suited for commercial vehicles and buses, however, for off-highway applications, as well as in combination with an SCR. This technology is also used in stationary engines, railways or shipping. HJS ceramic filter systems are available for application both in the original equipment and in retrofit

Active systems such as the SMF ® -AR (sintered metal filter with self-sufficient thermoelectric regeneration) are often used in mobile machines and stationary applications in the case of widely differing application profiles with exhaust gas temperatures that are often too low.
- Reduction of soot and fine particles by more than 99%
- Reliable filter regeneration even at low exhaust gas temperatures
- Regeneration without DOC enables operation even with high sulfur content of the fuel
- Flexible adaptation to different machines and engine outputs
- The high ash compatibility ensures long mileage.
- The modular design makes it easier to dismantle the system during service.

Many commercial vehicle applications, mobile machines, and stationary applications have load profiles that, owing to the low exhaust-gas temperatures, necessitate the use of active thermal management in order to guarantee full functional reliability of the exhaust aftertreatment system.
- Ensures Compliance with Emission Standards
- Maintains optimal exhaust temperatures for reliable DPF regeneration and DeNOx (SCR) system performance, even under low-load conditions.
- Prevents non-compliance risks by ensuring emission targets are met over the entire system lifetime.
- Active Thermal Management for Low-Temperature Applications
- Solves the challenge of low exhaust-gas temperatures in commercial vehicles, mobile machinery, and stationary engines.
- Uses two interlinked actuators to actively control heat, enabling efficient aftertreatment without engine modifications.
- Self-Sufficient & Engine-Independent System
- Unlike engine-based thermal management (which has limitations), HJS’s standalone system ensures consistent performance regardless of engine load or ambient conditions.
- Reduces dependency on engine recalibration or fuel dosing strategies.
- Advanced Heating Technology for Maximum Efficiency
- Features an electrically heated oxidation catalyst (eHOC) for faster light-off and improved cold-start performance.
- Enhances HC (hydrocarbon) conversion and particulate filter regeneration efficiency.
- Robust & Reliable Operation
- Designed for harsh conditions, ensuring durability in construction equipment, trucks, and industrial applications.
- Minimizes machine downtime by preventing failed regenerations or aftertreatment faults.
- Future-Proof Solution
- Adaptable to even stricter future regulations.
- Combines burner-based systems, HC dosing, and catalytic conversion for maximum flexibility.

HJS has specially developed a Diesel Particle Filter from Sintered Metal (Sintered Metal Filter SMF®) to reduce soot particles and eliminate diesel exhaust gases, and received the German Environmental Prize for it.
For the reduction of the gaseous pollutants, in combination with the diesel particle filter, jointly with the project partners Daimler and JohnsonMatthey, HJS has developed the SCRT® system (Selective Catalytic Reduction Trap). With this modular structured system, nitrogen oxides are also removed almost completely from the diesel exhaust gases.
Area of application
The SCRT®system is used both in the private car and commercial vehicle sectors, and is the leading system architecture with vehicles of generation Euro VI/ 6 or EPA 2010 when it involves clean exhaust gases. In addition, at the latest from 2019, Stage V will also be standard on a lot of off-road diesel engines, i.e., for example, in use on construction machines, mining machinery, as well as agricultural and forestry machines.
This technology is also used for fixed-in-place engines or railways, and shipping. HJS SCRT® systems are available both for application in the original equipment and for retrofit.
