Polyamide for Low-Friction Timing System

February 4, 2016

Linda Trego

Stanyl PA46 from DSM has been chosen for low-friction slide shoes within the timing system of turbocharged gasoline engines. The timing system parts are produced by Quadrant Creative Molding & Systems, and the system items are supplied by Tsubakimoto UK. These engines represent the latest advancements in engine downsizing, and they offer an optimized combination of drivability and fuel consumption, with significantly lower CO₂ emissions, despite their higher power. Stanyl PA46 is already widely used in engine components because of its ability to withstand the highly demanding conditions found in the slide shoe, which include high temperatures, high loads, high velocities, harsh chemical environment, and heavy vibrations. Until now, the current industry standard for engine components has been Stanyl TW341, but for the new engines, this PA46 material, Stanyl TW371, provides even better friction performance. Tests have shown a 20% reduction in friction by Stanyl TW371. This provides extra benefits in terms of reduced CO₂ emissions and improved fuel economy.
