Powertrain & Engine System Components

Higher Performing Powertrain & Engine System Components

The drive to reduce emissions and improve fuel economy is urgent, making every powertrain and engine system component a candidate to improve efficiency, integrate function, reduce weight and lower cost – areas where DuPont excels.

Materials play a critical role in helping to reduce emissions, boost fuel economy and improve efficiency in powertrain technologies. DuPont offers the broadest portfolio of materials capable of withstanding today’s harsh engine environments and the most experienced and global development staff to ensure solutions developed today are on the road tomorrow.

Improved Performance: Downsized engines require power-boost technologies such as turbocharging and exhaust gas recirculation (EGR) to improve fuel economy without sacrificing performance. DuPont lightweight, high-heat resistant materials, including aramid fibers such as DuPont™ Nomex® and Kevlar®,
can help take some weight off the added components.

Lightweighting: Our long-life, chemically resistant thermoplastics, composites and sealing materials let auto designers integrate multiple hoses and ducts, eliminate clamps, and streamline design in tight spaces to improve air flow and reduce weight and cost.

Powertrain Efficiency: Get more power to the wheels – where it belongs – with high-performance synthetic lubricants and DuPont™ Vespel® parts that protect moving parts from wear and significantly reduce frictional loss.

EPA Guidelines

Brief summary of the US EPA's (Environmental Protection Agency) "Level's of Protection (LOP)" as applicable to those individuals involved in handling hazardous materials. LOP's are based on the type of respiratory protection required to ensure the safety of the user under the specified conditions of use.

Alternative Drive Vehicles
Committed to Sustainable Mobility
Withstanding Hotter Running Engine

Engine downsizing, lightweighting, turbocharging, direct injection, and exhaust gas recirculation are all responses to the drive for greater fuel economy, higher engine efficiency and lower CO2 emissions. But these advances come at a price. They generate more heat, and involve more aggressive gases, fluids, and acidic gas/air mixtures, often under high pressure.
