What are EGR and DPF Systems?

Exhaust Gas Recirculation (EGR) and Diesel Particulate Filter (DPF) systems are integral to minimizing the trucking industry’s carbon footprint. The EGR system recirculates a portion of the engine's exhaust gases back into the combustion chamber, reducing the amount of oxygen available for combustion and lowering peak combustion temperatures. This helps reduce NOx emissions, making diesel trucks more environmentally friendly. DPFs, on the other hand, capture and trap soot and other harmful emissions to prevent them from being released into the environment. These filters require regular cleaning and maintenance to function correctly.

The Importance of EGR and DPF Repairs for Your Fleet

Some of the most common after-treatment problems, such as stuck EGR valves and clogged DPFs, won't only run you the risk of non-compliance with DOT regulations, but they can also cause significant performance problems in your fleet. Over thousands of miles on the road, the EGR valve can get stuck open, sending more exhaust gases back into the combustion chamber than what is required. This will drop the temperature in your combustion chamber and can lead to extensive engine damage.

Clogged DPFs are a common issue in light-duty trucks, as lower speeds in traffic won't meet the requirements the system needs to set off an automatic cleaning cycle. A Clogged DPF can cause your truck to enter limp mode and display a DPF service light, leading to a loss of power and decreased fuel efficiency. Regular EGR and DPF maintenance can prevent these issues and ensure that your fleet is running at optimal performance.

They got me right in when I needed a repair during a trip. Fair pricing with quality work. Went there worried since on the road repairs can go so wrong but left very happy.
