EGR Systems

Proven world-wide by millions, emission control components from Pierburg are used today in modern vehicles to keep the air and the environment clean.

Through the exhaust gas return system and the secondary air system already up to 50% of the emissions in the exhaust gas are eliminated before they reach the catalyst. The most of these components are controlled by the On-Board Diagnosis (OBD)-system.

EGR valves

  • 95 types of electric and pneumatic EGR valves in our product range.

  • Faulty EGR valves become evident through customer complaints such as black smoke, power loss, poor idling or insufficient acceleration.

  • Pierburg EGR valves cannot be replaced by other suppliers.
  • Every modern diesel engine is equipped with an EGR valve.

EGR cooler

  • Targeted cooling of the recirculated exhaust gases.

  • The cooled exhaust gas recirculation reduces the temperatures in the combustion chamber, as well as the level of nitrogen oxide formation.

  • The lamella geometry developed by Pierburg reduces the danger of sooting in the radiator.
  • With or without pneumatic bypass flap.
  • Including with oil cooler and oil filter in one component.
