In 2011 with LML Duramax, DEF aka Diesel Exhaust Fluid was introduced. Regen is the process of burning off accumulated soot in the DPF, also known as Diesel Particulate filter. Soot is a byproduct of unburnt fuel aka particulate matter. We can cover more of the Regen process in a different video so please comment below if that’s something you would be interested. DPF temperatures during an active regen will quickly climb to 1000 deg F in order to quickly burn collected soot off and allow the DPF differential pressure to come back down. Temperatures during active regen can reach as high as 1300 deg F. Driving the truck you'll notice a different engine pitch, and higher idle while stopped. You may feel extra heat underneath the truck during active regen and will occasionally catch a funny smell out of the exhaust. Now that we’ve explained the Regen process, those vents are starting to make sense… But Why is it so important to cool the exhaust? Take a look at this Exhaust tip that’s been powder-coated. Through several regens during our 2,000 mile drive back from SEMA, it has melted and burnt the powder coating on the tip. This is a DPF back 5” exhaust btw which didn’t have any vents. Curious to see how this works compared GM’s stock exhaust. I know what you’re thinking.. don’t powder coat exhaust tips… Well, on vehicle that do NOT go through Regen, powder coated tips seem to work fine. However, you may want to cerakote for this application since it can withstand more heat. Cooling the exhaust gasses before exiting out the tailpipe is important and has real life benefits. Because the tailpipe is exposed, the vents bring cooler air to reduce the temperature so you don’t burn yourself if you happen to walk behind your truck during or right after an active regen, and accidentally touch the exhaust tip, it could cause some injuries and result in lawsuits… Also imagine pulling your trailer hundreds to thousands of miles with truck going through several active regens. It could melt the trailer. If you live in a city and the truck goes through an active regen, it could potentially damage the vehicle next to the exhaust as well as your own vehicle’s paint. Lastly, cooled temperature can reduce wildfire according to the state of California.. JZU84_awEgo |
