Modern-day diesel engines have a lot of technology and systems designed to make them as efficient and environmentally friendly as possible. One such system is your Exhaust Gas Recirculation (EGR) system. This forces a portion of your exhaust back into your engine’s combustion chamber, therefore limiting the amount of carbon released into the atmosphere. Although these systems do great things for our environment, they introduce more points of potential failure. Over time these systems experience wear and tear and may require repairs or maintenance. Here at Whitecloud Mechanical, we’re emissions experts. We know the ins and outs of your EGR system better than anyone else around. You can count on our technicians to have your engine running better than ever before.
Common EGR Problems
Leaking EGR Valve
Your EGR valve is supposed to be closed at all times. However, over time it may start to leak or break open altogether. This is often due to a build-up of contaminants in your fuel, whether it be soot, dirt, or other debris. When this happens there are a variety of symptoms you may experience. First and foremost, you’ll likely notice a large decrease in fuel efficiency and a lack of engine power. You may also notice your vehicle idles roughly and may even stall at low RPMs. It’s very important that you bring your truck in for service if you believe you have a stuck EGR valve. On the one hand, you’re vehicle’s performance and health is in steep decline. On the other hand, the carbon being emitted from your vehicle is significantly amplified and is in violation of environmental rules and regulations.
Diesel Particulate Filter (DPF) Blockage
Diesel Particulate Filters (DPF) are designed to capture emissions before they enter the atmosphere. It works similarly to that of a catalytic converter, but is far more intertwined with your engine. Over time your DPF can get clogged, which can have serious implications for your vehicle. Common symptoms of a bad DPF include poor engine performance and decreased fuel efficiency. Newer diesel engines have been known to go into “limp mode” when DPF issues arise.
