As small-displacement turbocharged engines become the mainstream in the market, the working environment of their core component, the turbocharger, is becoming increasingly harsh. To regulate the industry development, relevant national departments have officially approved and issued a new national recommended standard for key components of turbochargers, which will be officially implemented in the near future. This standard clarifies the composition, characteristics, and structural requirements of oil film bearing materials for vehicle turbochargers, aiming to provide a unified technical basis for turbocharger enterprises to select high-performance and high-reliability bearing materials.

Although this standard primarily targets bearing materials, as a crucial component in the engine wheel system, the performance of the turbocharger directly impacts the load and lifespan of both the wheel system and the tensioning system. The upgrading of industry standards will indirectly drive the entire front-end wheel system, including pulleys and tensioners, towards higher precision and reliability, fostering collaborative technological advancement across the industry chain.
