Parts Integration & Performance Achieved with PA-Based Part
Volkswagen and Röchling Automotive (roechling.com) have developed an air-intake manifold with an integrated liquid charged air cooler for VW TSI engines that is said to be 40% smaller than comparable components for turbocharged engines and that has 20% fewer parts, as well as less mass.
The cooler is produced with a polyamide (PA), Akulon K224-HG6 from DSM Somos Engineering Plastics (dsm.com). The material is 30% glass reinforced.
There are performance benefits to the VW TSI engines, as well. Said Marco Barbolini, product manager at Röchling Automotive, “Integrating the heat exchanger into the intake manifold reduces air volume, giving the engines more punch, and eliminates a bunch of quite expensive parts.”
Material selection is the key factor for making vehicles lighter. Here’s a quick look at the best options that also lend themselves to quick-turn, fully functional prototypes.
Generally, when OEMs produce aluminum engine blocks (aluminum rather than cast iron because cast iron weighs like cast iron), they insert sleeves into the piston bores—cast iron sleeves.
