    Continental brings together four strategies to reduce emissions and cut fuel consumption

    More efficient drive systems, electric components for powertrain and subassemblies, weight savings through lightweight design and ergonomic assistance systems: the Automotive Group delivers scalable solutions for the automotive industry

Frankfurt am Main/Regensburg, July 20, 2009 Lowering the fuel consumption and

    emissions of cars and commercial vehicles is one of the most important issues for the future of sustainable individual mobility worldwide. The Automotive Group of the global automotive supplier Continental is bringing together four strategies to reduce fuel consumption, and will be able to offer car manufacturers a comprehensive package of solutions for the low-consumption vehicles demanded by the market. These measures will also ensure compliance with national and international legislative requirements for emissions standards and the reduction of CO. 2

“Our goal of enabling resource-efficient motoring with a reduced environmental impact

    cannot be achieved through individual measures alone. It requires a number of intelligent innovations that cover the full range of systems,” said Dr. Karl-Thomas Neumann, Chief

    Executive Officer of Continental AG and Head of the Automotive Group. “These innovations

    also have to be scalable, so that they can be offered in price-sensitive vehicle classes and markets.”

Four strategies for greener driving

    The Automotive Group is focusing on four complementary strategies to reduce the impact of vehicles on the environment and to ensure the sustainable use of resources. This integrated systems approach will help car manufacturers to bring vehicles to market that maximize fuel economy while minimizing environmental impact.

    ; Continuous optimization of fuel and energy consumption, for example by reducing

    engine size with the help of turbocharging and direct-injection technology

    ; Electrification of the drive train and other vehicle functions through the development

    of hybrid and electric components and electric power steering

    ; Ergonomic, pro-active driver assistance systems and the use of navigational

    information by the various control units

    ; Weight-saving design through optimized manufacturing processes and selection of

    materials, as illustrated by the example of our brake calipers and electronic braking


    More efficient drive systems: lower consumption with a more enjoyable drive The dominant trend in engine development today is “downsizing”: engines with a lower cubic

    capacity but greater specific power. This can only be achieved by the use of turbocharging. The Powertrain division has now brought the first turbocharger system for internal combustion engines to market maturity. The combination of small cubic capacity, direct injection and optimized valve timing with high specific power allows the engine to operate within ranges which are thermodynamically highly efficient. Turbocharger technology and

     emissions to be reduced by up to 15 percent. Clever innovations downsizing enable CO2

    include the automated assembly of the turbocharger and the electronically controlled e-wastegate system that will be available in the future. This offers faster control and greater precision than conventional systems, and thus increased scope for reducing fuel consumption. The modular design also makes the turbocharger easy to adapt to a variety of engine sizes.

    Direct injection systems for diesel and gasoline engines deliver high performance and maximum torque while keeping consumption low. The Powertrain division is facing up to the challenges posed by the introduction of the Euro 6 emissions standard with its latest generation of piezo injection nozzles for the diesel engine. The degree and length of time the injector is open can be controlled more precisely when the nozzle needle is directly influenced by the piezo element without the need for an intermediate hydraulic system. This allows the option of injection rate shaping as an alternative to the usual multiple injection method used in the past. With this design, the piezo actuator acts as a sensor by reporting

    the precise position of the nozzle needle to the control unit, producing the first self-contained

    emissions to be reduced by 20-flow rate control system. Piezo direct injection enables CO2

    25 percent compared with an engine with a traditional manifold injection system. The combination of brushless fuel pump (EC pump) in the supply unit and electronics to regulate demand produces an additional saving of 1-3g CO per 100km. 2

    Automatic transmissions will play an increasingly important role in the market. This will require precise gearshift control so that the engine operates as often as possible within speed ranges which consume the least fuel. As the global technology leader in the transmission control market, Continental can supply control systems for the complete spectrum of automatic transmissions. The double clutch transmission in particular combines the convenience of an automatic transmission with the efficiency of a manual system.

    The innovative technologies for exhaust aftertreatment and thus for the reduction of emissions also extend to essential components in the exhaust pipeline. Continental sensors measure variables such as exhaust gas temperature, soot or NOx content and work out how efficiently the catalytic converters are operating so that regenerative or regulative countermeasures can be initiated by the injectors in the exhaust pipeline. This improves particulate filter regeneration and the control of the SCR system for the selective catalytic reduction of nitrogen oxides. Continental also has a strong partner for catalytic converter technology, thanks to the 50 per cent stake it has taken in Emitec.

    Electrical components for powertrain and subassemblies save fuel

    The transition from internal combustion engine to the zero-emission electric car of the future is already well underway. A representative survey of German motorists carried out on behalf of Continental in spring 2009 showed that almost one in nine car drivers can “entirely”

    imagine switching to an electric car for their next vehicle.

    “The stated aim of Continental is to consolidate its leading position as a supplier in this field,” stressed Dr. Neumann. “50 percent of the global population already live in or near urban

    areas, which makes the possibility of completely emissions-free driving in those areas ever more important.” Hybrid and electric drive systems go a long way towards achieving this
