The EGR, or Exhaust Gas Recirculation system, is one of the most important components in any automobile engine. Understanding how it works and making sure that yours is in good condition is therefore essential if you are interested in keeping your truck running efficiently. Most of the modern truck engines made in the past two decades or so have an EGR valve fitted. This means that the only way you can be sure that your truck engine does not have one is if it’s a very old truck.
In a nutshell, the EGR is there to reduce emissions. It does this by rerouting some of the exhaust gases coming from the engine back into the combustion chambers in the engine. This has the effect of reducing the temperatures within the combustion chambers.
When the air/fuel mixture in an engine is burnt at a very high temperature, greenhouse gases such as nitrous oxide tend to be produced. By reducing the combustion temperatures through the use of the EGR valve, this is reduced dramatically without having a significant impact on the efficiency of the truck. In the end, the presence of the EGR makes your truck more environmentally friendly.
As a truck owner, it’s important that you keep the EGR valve in good condition. Since it has a direct impact on how the engine works, any problem with the EGR will manifest either as increased fuel consumption or reduced performance. Learning when to have it maintained or replaced is therefore important. Some of the signs that could point to a faulty EGR include:
These are the two common problems that afflict the mechanical EGR valves, and thankfully they are easy to fix. All you need to do is identify a competent garage, and have them fix it for you. If you are handy with your tools, you can even maintain and replace the EGR valve with ease. Of course, to do the latter, you will need to buy high quality spare parts from the right sources.
