AI Technical Summary
Lubricating oils for continuously variable transmissions face a challenge in achieving a balance between high friction coefficient and noise resistance, particularly in chain-type transmissions where noise is more easily generated, and existing compositions do not sufficiently meet this demand.
A compound represented by formula (1) is synthesized and used as a friction adjusting agent in a lubricating oil composition, which includes a succinimide compound, to achieve a high friction coefficient between metals and high noise resistance, with specific structural parameters optimizing solubility and performance.
The lubricating oil composition with the synthesized compound achieves a high friction coefficient and improved noise resistance, effectively addressing the balance between these two performance metrics.
