The all-new G-Class makes its public debut at the Detroit auto show in G550 form. Completely redeveloped and fitted with a 4.0-liter V8 biturbo gasoline engine offering 427ps and 450 lb-ft of torque at 2,000rpm to 4,750rpm, despite near-identical looks to its predecessor plenty has changed for the Mercedes-Benz SUV.

Royal DSM unveils new material to cut frictional torque

Royal DSM, a global science-based company, has launched an innovative new high performance material based on Stanyl polyamide 46. This new material, Stanyl HGR1, reduces frictional torque in engine timing systems, providing OEMs with a cost-effective tool for reducing fuel consumption.

Part of the frictional torque arises in engine timing systems when the timing chain moves over an element that keeps it under tension. This chain tensioner is often injection molded in polyamide 66, but increasingly this material is being replaced by DSM’s Stanyl PA46, owing to its improved performance, both in terms of mechanical properties, as well as its frictional and wear characteristics.

DSM has continued to work on developments to improve the properties of Stanyl PA 46 for use in chain tensioners. Stanyl HGR1 and the next generation Stanyl HGR2, which will be introduced soon, offer further enhancements in friction reduction. Extensive tests have proven that chain tensioners in Stanyl HGR1 produce lower frictional torque than any other material at relatively low engine speeds ranging from idle to 1800rpm. HGR1 also performed well at vehicle cruise speeds.

"By substituting PA66 with Stanyl HGR1 in the timing systems chain contact surfaces, frictional torque can be cut by 0.65 Nm," said Bill Burnham, DSM business development manager. “This equates to a fuel efficiency improvement of over a mile per gallon (over 0.4 km/L) over the drive cycle; that’s a substantial amount! In comparison to PA66, Stanyl HGR1 delivered 10% lower frictional torque within the critical engine speed range between 650 and 1800rpm.”

Stanyl HGR1 polyamide 46-based material has already made its market debut on the latest version of the Pentastar V6 engine, built by Fiat Chrysler America (FCA) and fitted to numerous vehicles (pictured). The new material reduces frictional torque in the Pentastar engine timing system, ultimately helping reduce fuel consumption.
