Truck EGR & DPF Services in Charlton, MA

Understanding how these work, the maintenance they require, and signs of failure can help keep you on the right side of regulations and avoid expensive penalties.

EGR and DPF systems are essential to your truck meeting emissions regulations. Understanding how these work, the maintenance they require, and signs of failure can help keep you on the right side of regulations and avoid expensive penalties.

EGR Systems

Exhaust gas recirculation (EGR) systems, as the name suggests, recirculate a portion of your truck’s exhaust gas back into the combustion chamber. This lowers the amount of oxygen in the chamber and the combustion temperature, which in turn reduces the amount of harmful nitrogen oxide (NOx) generated during combustion.

EGR System Maintenance

To maintain a clean and efficient EGR system that keeps within regulatory compliance, enhances engine performance, and reduces the risk of costly repairs, regular maintenance is essential. At C. M. T. S., our skilled team meticulously inspects and cleans all components, including the EGR valve, cooler, and pipes, to ensure that they are free from carbon build-up and working properly. 

Signs of EGR Failure

Detecting early signs of EGR system failure can save you from major headaches down the road. Keep an eye out for these indicators that your EGR system may require attention:

  • Check engine light
  • Rough idling
  • Increased fuel consumption
  • Engine performance issues
    (Lack of power, reduced acceleration, or a decrease in overall performance)

If you notice any of these, then pay us a visit at C. M. T. S., Charlton, MA, immediately. Ignoring these can not only cause more expensive issues to develop, but you could also be subject to expensive fines of over $45,000 from the EPA. 

DPF Systems

Diesel particulate filter (DPF) systems trap particulate matter (PM) such as soot and ash and prevent them from entering the atmosphere. They also work in conjunction with a diesel oxidation catalyst (DOC) to convert carbon monoxide and hydrocarbons into less harmful gases.

DPF System Maintenance

Like an EGR system, our team will thoroughly inspect and clean your DPF system to return it to optimal condition. However, forced regeneration may be required to achieve this. This is where one of our team members manually overrides your system's ECM to raise the exhaust temperature to a point where excessive PM is burned away. 

Signs of DPF Failure

Recognizing signs of DPF system failure is crucial for timely repairs and avoiding costly replacements. Keep an eye out for these warning signals:

  • DPF warning light activation
  • Frequent regeneration cycles
  • Reduced engine power
  • A noticeable increase in exhaust smoke, particularly black smoke

Remember, if you fail to maintain your DPF, you could face extreme financial penalties as well as further damage to your vehicle. Don’t take that risk; visit us at C. M. T. S., Charlton, MA, today.
