A brief talk about commonly used extreme pressure and anti-wear additives in lubricating o......

To achieve better lubrication and wear resistance while keeping the oil film economical, adding suitable friction modifiers is necessary. Friction modifiers generally refer to additives that can enhance the anti-wear performance of lubricating oil, effectively reduce the friction coefficient of contact surfaces, and thus reduce friction and wear. Based on their development history and mechanism, they can be briefly divided into fatty agents, normal anti-wear agents, and extreme pressure anti-wear agents.

A brief discussion on the categories and usability of lubricating oil antioxidants

To date, antioxidant products for lubricating oil have developed over nearly a century, forming specialized categories with distinct targeted functions. For example, in terms of chemical composition and structure, there are sulphur-based, phosphorus-based, nitrogen-based, amine-based, phenol-based, and phenol ester-based types. According to different mechanisms of action, they can primarily be classified as free radical terminators, peroxide decomposers, and metal deactivators, among others, and they can also be categorised based on the differences in their actual effects.

A Brief Discussion on the Viscosity and Viscosity Index of Lubricating Oil

When talking about the viscosity of lubricating oil, we must also mention another very important concept that seems similar to viscosity but is completely different, namely the Viscosity Index (VI) of lubricating oil.

The Asian economy shows resilience amid tariffs and uncertainty

According to the latest article from the International Monetary Fund, despite facing multiple challenges such as high tariffs, weakened external demand, and policy uncertainty, Asian economies have shown resilience beyond expectations. This resilience is attributed to export-oriented strategies, technological investment, and policy support. To maintain strong and sustainable growth in the future, Asian countries urgently need to promote a transformation of their economic structures towards domestic demand and accelerate deepening regional integration.

Briefly describe the engine piston and its lubrication

The engine piston mainly consists of three parts: the piston crown, the piston head, and the piston skirt. The piston crown and the cylinder wall form the engine's combustion chamber, where the fuel-air mixture burns to push the piston downwards. The piston crown must endure high temperatures and pressures, with temperatures generally reaching 300-400°C and gas pressures up to 3-5 MPa for petrol engines and 6-9 MPa for diesel engines.
