Based on science and technology, the Dutch Royal DSM Group, which is active in the fields of health, nutrition and materials, cooperates with the vehicle manufacturers globally to modify them. PA46 Stanyl® HGR2Resin-made low-friction tensioning systems are being used in more and more passenger vehicles. Stanyl® HGR2With traditional PA66In comparison, friction can be reduced under boundary lubrication conditions 20-40%, thereby improving the vehicle's fuel efficiency, further reducing the car's carbon dioxide emissions, and making driving more convenient. 'green' .
70-80% of the energy generated by the fuel combustion of passenger cars will be lost through various forms. Mechanical friction loss is a part that can not be ignored. In the currently used timing system, the friction between the chain and the tensioner part It accounts for 43% of the total friction. Therefore, effectively reducing the friction loss of the tensioner becomes a key link to improve the fuel efficiency of the vehicle.
DSM modified PA46 Stanyl® HGR2 resin provides a low-friction, highly wear-resistant material solution for automotive timing chain systems. Commercial PA66 is the most commonly used material for chain guide surfaces, using Stanyl® HGR2 under boundary lubrication conditions Replace PA66, which can be equipped with a selected model of 5.0L V8 engine, reduce the system friction by 20-40%, thereby increasing the fuel efficiency by 0.4%, equivalent to a weight reduction of 18 kg for the entire vehicle, and the “traditional” plastic substitute steel scheme In comparison, the cost is only one-tenth. In addition, Stanyl® has excellent wear resistance and fatigue resistance, and its service life is seven times that of PA66. Whether it is at high chain tension or due to the engine When the cabin space is limited, resulting in a small radius of curvature of the chain guide rail and the tensioner guide rail, or when the pitting wear starts due to loosening of the chain, Stanyl® can provide stability throughout the life cycle of the engine.
Stanyl® is a commercially proven superior material solution and has become the industry benchmark for automotive tensioning systems. In every ten new cars, at least six cars use Stanyl® PA46 in their timing chain system. Nissan, Suzuki, Ford and several other major automakers have selected Stanyl® HGR2 as a low-friction guideway material for their new generation of energy-saving turbocharged gasoline engine timing systems.
Ford Motor won the 2017 SPE Automotive Innovation Award for its adoption of the Stanyl® HGR2 Innovative Materials Solution. The environmental benefits of this material solution are substantial: 12,000 barrels of fuel consumption or 5,000 tons of greenhouse gases can be saved each year. Emissions. Stanyl® HGR2 has been applied to the chain tensioner arms of the Ford F-150 and Mustang, and will soon be applied to Ford models worldwide.
Stanyl® is a family of high-performance polyamides 46 that maintain their mechanical properties for long periods of time at temperatures up to 230° C. Stanyl® has excellent rigidity at high temperatures, fatigue resistance and excellent wear resistance. Applications For nearly 20 years in the automotive sector. Stanyl® is used in powertrain solutions that help reduce weight and withstand high temperatures. In addition to being applied to timing systems, it can also be widely used in front-end accessory drives, clutch systems, bearings and bearings. Push washer parts.
