IAA 2011: Solutions for environmentally friendly vehicle construction

ContiTech travels along in the cars of the future

September 2011At Continental AG's IAA 2011 corporate stand (booth A07 in hall 5.1), ContiTech will be showing off components and systems that extend a car’s life while at the same time making the vehicle more comfortable and convenient to use. Many trend-setting launches of the IAA also drive with ContiTech technology.

Interior materials are kind to people and the environment

In the matter of greater fuel efficiency and reduced pollutant emissions, the auto industry is devoting increasing attention to the development of lightweight materials. And that is precisely where recyclable, halogen-free TPO interior foils from ContiTech Benecke-Kaliko score better than conventional PVC materials. The lighter weight makes the difference. To top it all off, the foils are completely free of plasticizers. This ensures extremely low emissions and a healthy vehicle interior climate.

But it is not only there that these surface materials are kind to people and the environment. They are already so during the manufacturing process and again later on during recycling. The life cycle assessment that Benecke-Kaliko drew up on its interior material confirms this. The company was the first foil manufacturer anywhere in the world to do such testing.

The assessment included a comparison of TEPEO®’s complete life cycle with that of a standard PVC foil. The results were quite clear. In terms of CO2 emissions, the ultra-lightweight TEPEO® foil scored 48% better than the standard foil. In comparison with the standard trim material, the new Acella® Eco Natural interior material for vehicle seats and door paneling – with a renewable raw material content of up to 50 percent – cuts CO2 emissions by 15 percent. Part of the Acella® Eco family, Acella® Eco Natural is a product particularly kind to the skin and low in emissions. The Acella® Eco line-up has received Öko-Tex®’s most demanding certificate – the Öko-Tex® Standard 100. The products have thus been shown to be suitable for prolonged contact with human skin.

Technologies for low-emission engines

A further way to save weight and make vehicles more eco-friendly is to use plastic rather than metal components. ContiTech’s polyamide engine mounts and structural components can be found in vehicles from General Motors, BMW and Porsche. These ultra-strong components shave 50 percent off the weight of a comparable conventional aluminum engine mount. ContiTech is also developing new mounting concepts tailored to innovative and low-consumption drives, such as engines with cylinder deactivation or hybrid drives.

When it comes to purifying exhaust gases with the help of selective catalytic reduction (SCR) technology, components from ContiTech have also assumed a pioneering role. A heatable EPDM-based hose line module ensures that the urea required for the process does not freeze. ContiTech is now also offering this cutting-edge technology for more powerfully engined cars. Comprised of air conditioning lines and an internal heat exchange unit, the redesigned ECO AC product range ups the efficiency of air conditioning units. The weight and amount of refrigerant used have also both been reduced.

Improving drive belts is another way to reduce engine fuel consumption and lower emissions. CONTI® UNIPOWER ECO2-FLEX, the particularly flexible multiple-V-ribbed belt, reduces the power loss in auxiliary unit drives. High-performance multiple V-ribbed belts from ContiTech can also be found in fuel-efficient,
CO2-reducing start-stop systems. CONTI® OIL RUNNER, the oil-resistant timing belt, replaces chains in oil pump drives and camshaft timing assemblies and leads to a demonstrable improvement in emissions and noise behavior.
