Freudenberg shows innovations at International Auto Show

Clean engines for a clean environment

Freudenberg Filtration Technologies also help reduce emissions. The newly developed motor air-intake filters prove that lower emissions start with cleaner air intake. Modern, high-performance motors need clean air to reach their highest level of performance.

An engine intake air filter is designed to free incoming air from contaminants; however, caked on dust will increase filter resistance, using more energy to take in air, ultimately increasing CO2 emissions. Freudenberg Filtration Technologies solved this problem with the completely synthetic, energy efficient micronAir engine intake air filter that has a large dust intake capacity and low pressure loss. The engine intake air filter saves 0.6 g (0.02 oz) CO2 per kilowatt hour which is 60 g (2.1 oz) an hour for a car with a 100 kilowatt capacity.

Every engine intake air filter is a unique development from Freudenberg Filtration Technologies and is created in cooperation with partners and customers. The completely synthetic micronAir engine intake air filter will come standard in the new Mercedes Benz C Class starting next year.

Innovative nonwovens for various applications

Freudenberg's newly developed nonwoven materials used to clean the incoming air are primarily responsible for the engine intake air filter's properties. Freudenberg uses specially developed nonwoven materials in the interior air filters in numerous models exhibited at the IAA, such as those from BMW, Lamborghini, Mercedes, Mazda, Porsche, Seat and Skoda.

Even the first electric vehicle from Volkswagen, the VW E-Up, which will be presented in Hall 3.0 at stand A01, has an interior air filter from Freudenberg. Freudenberg Nonwovens supplied the base materials for the malleable carpets used manufacturers of various luxury car models.

Less friction - lower emissions

The Freudenberg Sealing Technologies Business Group developed an active breathing cap for drive shafts in e-mobility and hybrid technologies for the LESS or Low Emission Sealing Solutions campaign using Freudenberg nonwoven materials.

The intelligent design makes expensive ventilation valves unnecessary and the drives more affordable. Thanks to the innovative nonwoven technology, the permeable sealing cap allows for movement of air and prevents the entry of foreign bodies while also preventing lubricants from leaking out. The sealing cover is only one of several LESS products to help reduce emissions.

LESS is more. More responsibility - thus the name of the environmental protection campaign from Freudenberg Sealing Technologies that presents extensive sealing solutions to help reduce emissions. Freudenberg Sealing Technologies developed the gas lubricated mechanical seal Levitex.

The mechanical seal runs on a cushion of air thus generating 90 percent less friction loss compared to a conventional crankshaft seal. In a standard cycle, Levitex saves between 0.5 and 1 gram of CO2 per kilometer.

The development of Levitex is an important step toward the creation of completely frictionless sealing technology in engines and drastically lower CO2 emissions. Emission reducing LESS products can be found in the Mercedes GLA and the BMW 5-Series at the IAA.
