“The terrible mess your engine has to endure for cleaner emissions.” That’s how most mechanics would describe EGR.
And they’re mostly right. In internal combustion engines, EGR is a Nitrogen Oxide (NOx) emission reduction technique used in gasoline and diesel engines. EGR recirculates a small amount of the engine’s exhaust gas back to the cylinders. This dilutes the O2 in the incoming air stream and provides gases inert to combustion to act as absorbents of heat to reduce in-cylinder temperatures.
Although this technique sounds like a great solution in order to reduce NOx emissions, EGR also has a huge downside. The exhaust gas that’s recirculated back into the cylinder will increase engine wear as carbon particles wash past the piston rings and into the oil. And on top of that, these polluting particles also tend to clog the EGR valve and coat parts like the EGR cooler, intake ports and any sensors that are exposed to it, causing reduced performance and failing parts as a result.
Unfortunately, Alec GmbH can’t solve all these troubles, as this is inherent to EGR. However, we do have high quality remanufacturing solutions for EGR components. Our experience with other mechatronic automotive parts gives us a solid foundation in order to develop professional Tier 1 remanufacturing processes.
