Pierburg
Back at the start of the 90s, Pierburg had developed a secondary air pump system for effective after-treatment of the exhaust gases. This was necessary in view of the growing gap between untreated emissions and the stipulated limits.
The secondary air assists the catalytic converter during the engine’s warm-up phase since immediately after cold start, the converter fails to achieve any purifying effect. Only at a light-off temperature in the range of 300 to 350 °C does the converter come into operation. Injecting secondary air into the exhaust gas manifold gives rise to exothermal oxidation of the unburned carbons and carbon monoxides. The heat released in the process allows the converter to reach its operating temperature more readily.
