Exhaust Gas Recirculation (EGR)

“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.

Exhaust Gas Recirculation (EGR)


Highly automated methods are used in order to achieve a low cost high quality remanufacturing process:

  • Components are disassembled by using advanced automatic tools
  • Repetitive movements are carried out by robot arms
  • The cleaning procedure can be performed with automated wet blasting, automated dry ice blasting or even robotised ultrasonic cleaning
  • The component can be opened by CNC, its casting compound can be chemically or mechanically removed and (parts of) the housing can be renewed
  • All components and parts are transported by Automatic Guided Vehicles (AGVs)
  • More complex and specialist operations require our ultrasonic wire bonding machines, BGA placement equipment, various test and simulation platforms and fully automated glue dispensing robots

Our methods have been developed with a clear goal in mind: to achieve the highest possible efficiency. This results in a short turnaround time with a high reliability.

The entire process is carried out according to ISO9001 and ISO14001 in an ESD protected environment (IATF16949 to be expected).
