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.
