In 1909, the Pierburg brothers founded Pierburg GmbH in Berlin, which has been producing carburetors ever since. In 1986, the Düsseldorf-based Rheinmetall Group took over the company and began building up the automotive technology division. In 1998, Pierburg merged with Kolbenschmidt AG, which was also acquired by Rheinmetall, to form Kolbenschmidt Pierburg AG. This means that Rheinmetall AG is very well positioned when it comes to everything to do with the engine. Within the Kolbenschmidt Pierburg Group, Pierburg is considered an expert in the areas of pollutant reduction, air supply and throttle valves.
