How Do EGRs and DPFs Work?

EGR systems, or exhaust gas recirculation systems, work by recirculating 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. The EGR system includes the EGR valve, EGR cooler, and EGR control solenoid. 

DPFs capture and trap soot and other harmful emissions to prevent them from being released into the environment. Roughly every 300 miles, the engine management system initiates a regeneration process to burn off the trapped particles and keep the filter working effectively.

Stuck EGR Valves

Stuck EGR valves can cause significant performance problems in a heavy-duty truck. Over time, your EGR valve can get stuck open, shooting significantly more exhaust gases back into the combustion chamber. This will drop the temperature in your combustion chamber, leading to extensive engine damage if left unrepaired. Thankfully, Elite Truck & Fleet Service is fully equipped and qualified to repair or replace EGR valves on all types of diesel makes and models. Our experienced technicians can perform whatever type of repair you need to keep your after-treatment system in optimal condition.

Clogged DPFs

DPFs capture carbon and other diesel particulate matter to lessen the pollution that enters the atmosphere. When the filter becomes full, it may cause the truck to enter limp mode and display a DPF service light. However, this doesn't mean the DPF needs replacement—instead, at Elite Truck & Fleet Service, we have the equipment and expertise to clean DPF filters as necessary with our forced regeneration cycle service.

Courteous, professional staff that kept me updated throughout repairs. Excellent process for texting/emailing estimates. And wow, great customer service - owner Dustin delivered my truck to me himself on a weekend, with all repairs completed. Highly recommend.

Great shop and people! I was very glad to find this shop cause they were able to fix the mechanical issue of my box truck (truck didnt start due to bad injector seal) that other shops around were not able to. I definitely recommend this shop to any truckers in the area. Dustin is a great  person to deal with. His knowledge and experience is incredible and will help to keep your fleet running! Thank you, Elite Truck & Bus Center!

Dustin knew I was having issues with my AC on my Supra and was able to squeeze me in around my schedule. Once I got there, Luis went through a thorough diagnostic of my AC unit and saw there was a leak somewhere in the system. He recharged my AC and had me on my way! Elite was definitely a huge help. Thank you so much again!
