If you own a heavy-duty vehicle, chances are it uses an EGR system to reduce the Nitrogen Oxides (NOx) entering the atmosphere by recirculating exhaust gases back into the engine for combustion. Gallaher Fleet Solutions keeps those systems clean and working.
The heavy diesel mechanic team at Gallaher Fleet Solutions is a trusted name in NC for system and component servicing needs for all types of diesel vehicles.
Most fleet vehicles experience issues in their Exhaust Gas Recirculation (EGR) system at some point. Its job is to reduce emissions, but if it isn't in optimal working condition, a faulty exhaust system can end up putting unnecessary load on your engine.
Like the EGR, the diesel particulate filter (DPF) serves the same purpose — trapping soot from the exhaust in its honeycomb-shaped filter, storing it, and then burning it off. These two systems are necessary for the proper operation of your trucks, but they can run into many problems if they are not serviced regularly.

Towing and heavy loads take their toll. Our fleet EGR and DPF solutions keep the engine clean while improving fuel mileage and the life expectancy of your trucks. Call 704-960-8951 to learn more.
Both systems are essential to how your truck runs. Here's what to watch for — and when to bring it in.
The DPF system helps heavy-duty trucks travel long distances comfortably, but it's best to have it checked every 300,000 miles to avoid problems before they start.
Ignore DPF issues too long and your engine may start acting up. A clear indication is when the yellow light appears on your dashboard.
EGR coolers can plug with soot, which restricts the flow of gases through the system and puts extra strain on the engine.
Thermal cycling and constant system pressure can fracture the cooler internally. Timely EGR cleaning — or replacement if necessary — avoids further engine complications.
The DPF captures soot and burns it off through regeneration, the EGR cuts nitrogen oxides by recirculating exhaust gases, and the SCR uses diesel exhaust fluid to turn harmful emissions into nitrogen and water. Learn how these three systems work together — and why aftertreatment failures are among the most common and costly issues in modern diesel engines.
