Materials science: Helping the auto industry improve air quality


With over one billion* cars on the world’s roads today, air quality management has become the big issue.

Although the US still leads the way with a car population of nearly 240 million, the biggest explosion in numbers is taking place in China with 100+ million passenger vehicles already. Whether in China or worldwide, the inescapable fact is that noxious CO2 exhaust emissions from fossil-fuel combustion will grow exponentially if measures to improve air quality prove ineffective.


DuPont Greater China President Tony Su has invited leaders from the auto industry and Chinese government to collaborate on ideas to address what he calls ‘controllable’ causes of emissions that are contributing to air quality challenges facing Beijing and other parts of China.


DuPont has many programs that apply material science to help meet some of those challenges. For example, replacing metal with lightweight advanced plastics directly improves fuel efficiency and reduces vehicle emissions. Using advanced materials that reduce rolling resistance in tires and lower friction in transmission and driveline parts improves vehicle efficiency.


In this issue, we introduce the first of a series of three air management articles with a focus on fuel efficiency as a means of reducing CO2 emissions.


Alternative energy sources hold much promise for a cleaner future. Biofuels: Latest News predicts a doubling of biofuels production from 2013 to 2021, and outlines the plans DuPont has to open one of the world’s largest cellulosic ethanol biorefineries.


Wuxi No. 2 Rubber Co., Ltd. of Jiangsu Province, China, chose DuPont™ Vamac® AEM, and Ningbo Joyson of Zhejiang Province chose Hytrel® TPC, to help raise turbocharger hose and air duct efficiency in SAIC’s new 1.9 liter turbo diesel engine.


Our goal is to build on the success of collaborative programs to drive even more weight and cost from emerging applications in chassis, suspension and exhaust systems. Collaboration facilities like the DuPont Automotive Center, coupled with advanced materials and application development capabilities, can help us all to develop new ideas that reduce NOx and emissions, and get them into the market quickly.
