Diesel engines are renowned for their power and efficiency, but they also come with complex emission systems designed to reduce harmful pollutants. Two critical components of these systems are the Exhaust Gas Recirculation (EGR) valve and the Diesel Particulate Filter (DPF). When these components fail, it can lead to decreased performance, increased emissions, and costly repairs. Understanding the common causes of EGR and DPF failure can help you maintain your diesel engine in top condition. Here are the top three causes of failure for each component:

5 Things You Probably Didn't Know About The 2011-2016 Duramax EGR

Some of you reading this are probably screaming at the computer already.  Mentioning EGR, or any emissions equipment tends to prompt that reaction.  Take a moment to read about how the EGR equipped on the 2011 - 2016 Duramax is NOT going to ruin your engine.  Afterwards, if you still want to send a letter about how terrible emissions equipment is, please address it to your local Congressman. 

Below you will find 5 things you probably didn't know about the EGR (exhaust gas re-circulation).  Including  how it is different than previous models, why it works well, and a few other note worthy facts.  

A few things you've heard people say about the EGR that are NOT true about the LML EGR system:

• "They dump dirty exhaust back into your engine."
• "The EGR will gum up and fail constantly"
• "Deleting it will get you better fuel mileage."

REGEN is the burning of soot built up in a DPF. 

 The Emissions Equipment for diesel trucks has changed quite a bit through out the years. In 2004.5 all heavy duty diesel pickups had to install EGR's which is the exhaust gas recirculation system. Basically it turns exhaust into inert gas and directs the gas back into the combustion process. Then in 2007.5 the EPA required pickups to use a DPF. The DPF, or Diesel Particulate Filter, is a filter that catches soot, or unburnt fuel from the exhaust. Once the soot builds up, the exhaust heats up to burn the soot off. Starting in 2011 Diesel Exhaust Fluid is used to treat NOx emissions, in addition to the EGR and DPF treating the carbon emissions. 

The DPF is a crucile part of treating diesel emissions and each OEM utilizes and operates their DPF a little differently. Below, the DPF in the 2011-2016 LML Duramax is explained.

Did you know there is no reason to delete the emissions from your 2011-2016 Duramax? 

DuramaxTuner.com's SPADE is capable of adding up to 135HP to your EMISSIONS INTACT LML. 

Actually, more and more people are tuning their 2011 + Duramax (LML) with the emissions equipment intact.  This is a great option for Duramax owners that would like a nice, quiet, reliable, efficient truck that performs well every time. However, many LML Owners have some basic questions prior to pursining emissions intact tuning. 

3 SIMPLE THINGS YOU CAN DO TO HELP KEEP YOUR LML DURAMAX RELIABLE:

Your truck is generally one of the largest investments you will make, so keeping it on the road is priority number 1!

The LML Duramax is one of the best trucks GM has ever produced. With 397 Horse Power and 796 ft/lbs of torque from the factory, the truck has the power plant necessary to do just about any job you can throw at it. However, despite the massive improvements the LML has brought to the table, there are some all too common pitfalls that can make this beast a burden.
