Diesel mechanic performing EGR System & DPF cleaning services on semi truck in El Paso, Texas

While EGR systems recirculate exhaust gases to reduce nitrogen oxide emissions, DPFs capture and trap soot and other particulate matter that are harmful to the environment. However, over time, both components build up leftover residue, leaving you with a truck that doesn’t comply with federal DOT regulations and expensive repairs down the line.

Our mechanics are specialists in EGR system and DPF cleaning and repairs. With our help, you can maximize your engine's performance, minimize emissions, and avoid costly repairs. Trust us to keep your medium- or heavy-duty diesel truck at peak performance and experience the peace of mind that comes with reliable, high-quality diesel services.

EGR Systems Explained

Exhaust gas recirculation (EGR) systems are designed to help reduce the emissions of diesel engines by recirculating a portion of the exhaust gases back into the intake system, which in effect creates a more diluted and efficient combustion mixture. But although EGR systems are generally left unchecked over the years, they can quickly develop issues that affect the performance and efficiency of the engine. Common problems associated with EGR systems include stuck or damaged EGR valves, failure of EGR coolers, and carbon buildup in the intake manifold.

As combustion temperature rises, the average concentration of NOₓ emission increases. If you get the “check engine” light, a malfunctioning indicator lamp, a lack of power, rough idling, stalling, or poor fuel economy, it may be due to the build-up of soot, dirt, and other debris in your fuel and EGR system causing higher-than-average combustion temperatures. To avoid these issues, regular maintenance is key. This can include cleaning or replacing the EGR valve, replacing the EGR cooler, and using high-quality fuel and oil.

If you’re in the El Paso, Texas area, then come into Duran & Sons Diesel, and we’ll get you sorted.

DPF Explained

DPF (Diesel Particulate Filter), in combination with the EGR system, is at the forefront of reducing harmful truck emissions into the atmosphere. When the diesel engine runs, it emits particulate matter which goes through your truck’s exhaust tubing. Since the DPF is attached to the exhaust tubing, it filters and traps soot, dirt, carbon, and other carbon emissions, reducing the amount of pollutants released into the environment.

Common issues with DPFs include soot buildup, clogging, and failure to regenerate—a reduction in engine power and increased fuel consumption are tell-tale signs that your DPF is most likely clogged up. At Duran & Sons Diesel, our DPF cleaning and replacement services are designed to keep your diesel engine running efficiently to reduce the risk of costly repairs.
