An Exhaust Gas Recirculation (EGR) is a valve that also reduces emissions. It operates by cycling part of the exhaust gas back to the engine’s cylinders. The purpose of an EGR is to send gases away from the engine, reducing the amount of nitrous oxide running through the exhaust system. In newer trucks, the valves of EGR are electronically controlled and monitored by an onboard computer system. This allows our technicians to make critical corrections to keep your engine regulated.
A Diesel Particulate Filter (DPF) is a part of the exhaust system of your diesel truck that filters out pollutants and collects soot (carbon) particles. This works by pulling unburned or partially burned fuel from the exhaust before it can exit into the atmosphere. The fuel is then sent again through the engine to be fully combusted.
The EGR and DPF systems of your diesel truck are vital components for proper engine emission control. Routine maintenance is important to confirm correct engine function and proper emission compliance. Although they do reduce emissions, a strain can be placed on your engine by these systems. The lack of regular maintenance can result in further difficulties with your truck.
The EGR and DPF help reduce greenhouse gas emissions, but they can also get clogged up over time, especially if your truck is not on a scheduled maintenance program. If this takes place, you will find the efficiency and power of your truck significantly drop.
How to tell if your EGR and/or DPF systems are blocked
Both the EGR and DPF systems can become clogged. The emissions control systems are created for diesel trucks that are often used for towing heavy weight at long distances. Depending on how you are using your diesel truck, you could run into emission control system issues.
You will know that your DPF needs cleaning when the DPF light on your dashboard lights up. If the DPF is not cleaned or replaced, the build of soot will cause the DPF to be blocked. When the filter becomes clogged up with soot this is another sign that you need to have your DPF cleaned. Your oil level and fuel consumption levels may increase.
Foothills Group specializes in professional DPF cleaning. We utilize the latest technologies to clean your DPF better than competitive shops. Our DPF machine uses extreme airflow and high pressure to remove dirt and particles from both sides of the DPF. The DPF cleaning service offered through Foothills Group offers optimum filter recovery. A DPF replacement will only be recommended if we find internal damage that cannot be easily resolved.
