The Pierburg Group has been among the key partners of the automotive industry for more than 100 years and has successfully accompanied the development of automobiles since its establishment.

The main products developed and supplied by the Pierburg Group include control elements (actuators), control units, recirculation systems for exhaust gases, secondary air pumps and exhaust flaps.

Exhaust gas recirculation reduces nitrogen oxide emission in both diesel and petrol engines by lowering the combustion temperature and reducing the oxygen content in the intake air. In petrol engines, exhaust gas recirculation is used to de-throttle the engine in the part-load range. This leads to a reduction in fuel consumption.

EGR module

• EGR module consist of an EGR valve,
  an EGR cooler to cool the exhaust gases
  and optionally a bypass flap. 
• Integrating these functions into one
  component reduces the size of the finished
  product.
• The bypass flap is used to regulate the controlled
  re-routing of hot exhaust gas flow past the EGR
  COOLER or through the EGR COOLER in the cooling position. 

Low Pressure EGR Valve

• Is used in turbocharged engines in addition to the established high-pressure exhaust gas recirculation. 
• In this process, the exhaust gas is rerouted downstream of the DPF  and returned upstream of the compressor.
