Engine Systems

Power-to-weight ratios can be enhanced through thermoplastics, but optimizing the engine system for integrated functionality, superior protection against heat and oils, and the reliability to deliver for 150,000 miles – or more – is what DuPont is all about.

We were partners with the industry to bring the benefits of using thermoplastic and elastomers such as Vamac® in pioneering programs, such as:


The first high-volume thermoplastic manifold to North America; 
The first integrated air-fuel module in Asia Pacific; 
The first to bring thermoplastic rocker covers to the Americas on a global engine program. 
As the complexity of engine technology intensifies with multiple bridge-technology powertrains, partnering with a pioneer can help ensure your development is optimized to deliver the best cost, weight and time-to-market equation.
