At Northern Hydraulic & Fleet Service in Plaistow, NH, we understand the intricacies of truck and fleet maintenance. Two of the most critical components often requiring attention in diesel engines are the Exhaust Gas Recirculation (EGR) system and the Diesel Particulate Filter (DPF). Proper maintenance and timely repairs of these components are essential to ensure optimal performance, fuel efficiency, and compliance with emission standards.
Understanding the EGR System
What is the EGR System?
The EGR system is designed to reduce nitrogen oxide (NOx) emissions, which are harmful pollutants. It recirculates some exhaust gases into the engine's combustion chamber. This process lowers the oxygen concentration, reducing peak combustion temperatures and NOx emissions.
Common EGR System Issues
Over time, the EGR system can face issues like clogging due to carbon deposits. Symptoms of a malfunctioning EGR system include:
- Reduced engine performance
- Increased fuel consumption
- Engine knocking or pinging
- Check engine light activation
Importance of DPF in Diesel Engines
Role of the DPF
The DPF is an essential component in modern diesel engines, designed to capture and store soot particles, preventing them from being released into the atmosphere. As the DPF traps these particles, it periodically needs to undergo a process called regeneration to burn off the accumulated soot.
Indicators of DPF Issues
A malfunctioning DPF can lead to:
- Decreased engine performance
- Increased fuel consumption
- Potential engine damage due to backpressure
- Violation of emission standards

Had a good experience here. Had to bring my new Airflo dump body in for some adjustments. They had it in the next day and done in one day. It works great now, the way it should. Good communication too.
