The EGR and DPF system in your heavy-duty truck work together as part of your emissions system to limit the output of harmful exhaust. There are federal and state vehicle emissions and fuel economy standards which are monitored and these systems are necessary to ensure your vehicle remains compliant.

Regular maintenance is important to assure correct engine function and proper emission compliance.

The EGR and DPF system in your heavy-duty truck work together as part of your emissions system to limit the output of harmful exhaust. There are federal and state vehicle emissions and fuel economy standards which are monitored and these systems are necessary to ensure your vehicle remains compliant. As such, your truck’s EGR and DPF systems are essential components for proper engine emission control.  Regular maintenance is important to assure correct engine function and proper emission compliance. Although they do reduce emissions, these systems often put a strain on your engine and, especially if not maintained, can reduce the lifespan of your diesel truck.

What are EGR and DPF systems?

An Exhaust Gas Recirculation (EGR) is a valve that also reduces emissions. It works by circulating part of the exhaust gas back to the engine’s cylinders. This prevents DPF failure because it sends gases away from the engine, making it run more efficiently. The main goal of an EGR is to reduce the amount of nitrous oxide running through the exhaust system.

A Diesel Particulate Filter (DPF) is a part of the exhaust of your truck that collects soot to keep the air clean. It captures particles in a mesh net and reduces harmful emissions.

How to tell if your EGR and/or DPF systems are blocked

The EGR can become clogged and get stuck open or closed and your DPF system can quickly become clogged. Diesel trucks and their emissions control systems are designed for heavy towing at long distances. So, if you're using your diesel truck as a grocery-getter, you'll likely run into emission control system problems.  

You'll know your DPF is blocked when an orange light appears on your dashboard (it will look like smoke blowing through a filter). But why wait until it’s completely clogged? When dealing with a clogged EGR or DPF, cleaning is an essential service.  The service technicians at Absolute Repair are experienced in EGR and DPF repairs, maintenance and cleaning. Our technicians provide a detailed, quality cleaning and repair service for your EGR and DPF.
