Lubricants for metal V-belt type CVTs (B-CVTFs) must be able to produce a higher metal-metal friction coefficient and give excellent anti-shudder properties for lock-up clutch used in B-CVTs. This study intends to optimize various kinds of lubricant additive such as anti-wear additive. detergent and friction modifier (FM) for improving these performances of B-CVTs.
