(Virtual Showroom) Diesel engine emissions are a major health and environmental concern. At HJS Emission Technology SA, we help companies reduce Diesel Particulate Matter (DPM) directly at the source with advanced Diesel Particulate Filters (DPFs). But what exactly is DPM, and why should you care about it?

What Is Diesel Particulate Matter (DPM)?

Diesel Particulate Matter is a highly toxic mix of tiny particles found in diesel exhaust. It consists of carbon soot, ash, metal particles, sulfates, and silicates—many of which are carcinogenic. According to the World Health Organization (WHO), prolonged exposure to DPM increases the risk of lung cancer and respiratory illness.

DPM forms during the incomplete combustion of diesel fuel and engine oil, and the fine particles can easily penetrate deep into the lungs, causing lasting damage.

What Does Black Smoke from a Diesel Engine Mean?

Black smoke from your vehicle's exhaust is a warning sign. It signals inefficient combustion, which leads to increased fuel consumption, reduced engine performance, and higher emissions of DPM. Addressing this issue not only protects your health but also extends your engine’s lifespan and cuts maintenance costs.

10 Ways to Reduce Diesel Particulate Matter at the Source

1. Install a Diesel Particulate Filter (DPF)

A high-efficiency DPF can reduce diesel particulate matter emissions. Several other DPFs on the market are not up to standard, but HJS Diesel Particulate Filters with SMF technology have been proven and tested to reduce emissions by up to 99%. Explore our DPF solutions here. 

2. Perform Regular Maintenance

Keep your engine in top shape with routine servicing. Well-maintained engines produce fewer emissions and operate more efficiently.

3. Use Low Ash Engine Oil

Low ash oil burns cleaner and leaves fewer residues, helping reduce DPM accumulation in the exhaust system.

4. Optimize Diesel Pump Calibration

A correctly adjusted pump ensures optimal fuel-to-air ratio, boosting engine efficiency and reducing visible smoke.

5. Clean Diesel Injectors

Dirty injectors disrupt combustion. Use approved diesel additives to clean and protect your fuel injection system.

6. Replace Air Filters Frequently

Clogged air filters lower oxygen intake, increasing unburned fuel and black smoke. Clean air equals cleaner combustion

7. Replace Oil Filters Regularly

Clean oil filters prevent particle buildup and reduce the formation of particulate matter from burned oil.

8. Install an Exhaust Gas Recirculation (EGR) System

EGR systems lower nitrogen oxide (NOx) and particulate emissions by reintroducing a portion of the exhaust gases into the intake system.

9. Use a Diesel Oxidation Catalyst (DOC)

DOCs break down harmful exhaust compounds, including hydrocarbons and carbon monoxide. HJS can help you select a catalytic converter solution tailored to your equipment.

10. Use Clean, Low-Sulphur Diesel Fuel

Choose diesel with 50 PPM sulphur content or lower. Clean fuel enhances combustion and significantly cuts DPM emissions.
