Pierburg products are innovative components and systems for internal combustion engines that reduce emissions and improve performance and efficiency. Pierburg offers solutions for intake air pressure and flow control, exhaust gas recirculation, fuel tank insulation and idle control. Pierburg is a leading supplier to the automotive industry, with extensive experience and a global presence. Some of the most notable Pierburg products are:

- Fuel tank isolation valve (FTIV): This is a normally closed valve, which can be opened electrically on demand from the vehicle control unit. It is equipped with a mechanical bypass function, to balance the pressure inside the fuel tank in case of overpressure or depression inside the tank.

- Throttle body: Controls the pressure in the intake manifold depending on the need for exhaust gas intake into the engine cylinders. The opening of the throttle is controlled by an actuator based on information on the position of the accelerator pedal from the ECU. New variants of throttle bodies follow modern trends by using plastic material housings.

- Low pressure exhaust gas recirculation valve (EGR LP): Used in supercharged internal combustion engines in addition to high pressure exhaust gas recirculation. The exhaust gas is diverted downstream of the turbocharger and the diesel particulate filter and is returned upstream of the compressor and then to the cylinders. The new LP EGR variants follow modern trends by using plastic material housings.

- EGR module: An EGR module consists of an EGR valve, an exhaust gas intercooler and optionally a bypass flap. The main advantage of combining these components in a single unit is its low installation space requirement. The bypass flap allows the optional use of the intercooler. During a cold start, the intercooler is switched off due to the rapid warming up of the engine and the catalytic converter to the optimum temperature.

These are just a few examples of Pierburg products that contribute to improving the performance and environmental sustainability of modern engines.
