White Paper: High Performance Polymers for Automotive Air Management Applications

How to Meet the Latest Engine Performance, Emissions and Lightweighting challenges with DuPont Rigid and Flexible Polymers

Carbon dioxide (CO2) emissions reduction is arguably the most significant challenge faced by car manufacturers today. As CO2 levels in the atmosphere rise, so the bar in global CO2 auto emissions limits is being set lower and lower. Mandatory CO2 emission reduction targets set by European Union legislation required that new cars registered in the EU by 2021 should not emit more than an average of 95 grams CO2 per kilometer (g CO2/km) for the fleet average of all new cars. The progression of emissions legislation in the USA, Japan and other high car density nations is just as tough. Pressure on auto OEMs to reduce nitrogen oxides (NOx) emissions from diesel cars is also set to increase in 2018 in the wake of events that throw into question the true pollution level of diesel cars. The emissions control pressures on auto manufacturers, whether for petrol or diesel cars, will thus continue to intensify.

It is generally accepted that one of the most effective ways to reduce CO2 and NOx emissions is to reduce fuel consumption — and reducing engine size, or “rightsizing”, and vehicle weight are arguably the most effective and immediate paths to achieving that goal. Replacement of metals by plastics is the most effective way to make a vehicle lighter while gaining in easier processing, integration of functions and lower cost.

Engine Air Management System Components

This White Paper specifically looks at air management lines of turbo charged engines that control the flow of high-temperature air, aggressive gases and fluids under high pressure. Modern turbo charged engines are cooled by complex air and liquid cooling systems that manage the intake and exhaust flow of high-temperature air, gases and coolants, and integrate many vital elements including the air filter, air intake manifold, turbocharger, resonator, charge air cooler or intercooler, exhaust gas recirculation unit, closed positive crankcase ventilation.

Collaboration in the Value Chain

DuPont is responding to demanding CO2/NOx emissions reduction legislation. We help OEMs meet stringent requirements by developing materials that are resistant to higher temperature exposure and acid condensates such as exhaust gas recirculation (EGR) or Blow-by gas (BBG). The White Paper will explain how thermoplastics and elastomers allow for vehicle emission reduction, hence playing a key role in meeting targets. The White Paper then highlights how DuPont finds solutions by working together with customers throughout the value chain. Finally, you will find examples of DuPont’s latest offerings, tailored to the industry’s needs.
