After-Treatment

Reduce the emissions of harmful pollutants.
Make your vehicle more environmentally friendly!

MON-SAT 7AM - 8PM*
* For special circumstances, we will extend our hours and/or open on Sunday to minimize your fleets downtime.
frequent regenerations or frequent cleaning?

Inspection and cleaning of Diesel Oxidation Catalysts (DOC) and Diesel Particulate Filters (DPF)

Cleaning of the after-treatment is a regular maintenance procedure. However, if you are finding your vehicle requiring frequent regenerations or frequent cleaning, allow us to perform a check of the engine operation to ensure there is no issue mechanically or electrically with the engine that could be causing the issue but not issuing an engine code.

Contribute to a cleaner and more sustainable transportation

Clean up the emissions produced by internal combustion engines in buses and trucks.


The purpose of after-treatment is to reduce the levels of harmful pollutants, such as nitrogen oxides (NOx), particulate matter (PM), and hydrocarbons (HC), that are released into the environment through the exhaust of the vehicle.

Nitrogen oxides (NOx) and particulate matter (PM) are two of the main pollutants produced by diesel engines and can have serious impacts on public health, including respiratory problems and increased risk of heart disease. Additionally, NOx emissions contribute to smog and acid rain, which can damage crops, forests, and other natural habitats.

There are several different types of after-treatment systems, including diesel particulate filters (DPF), selective catalytic reduction (SCR) systems, and exhaust gas recirculation (EGR) systems.

DPFs trap and filter out particulate matter from the exhaust, while SCR systems use a urea-based solution to reduce NOx emissions. EGR systems recirculate a portion of the exhaust gases back into the engine to reduce the amount of oxygen available for combustion and thus reduce NOx emissions.

After-treatment systems are becoming increasingly common in heavy-duty diesel engines as a result of tighter emissions regulations and a growing demand for more environmentally-friendly vehicles. The goal of after-treatment is to help reduce the impact of diesel vehicles on air quality and public health, and to support the transition towards a cleaner and more sustainable transportation sector.
