Continuously Variable Transmission Fluids (CVTF)
Challenges for CVT Technology
In recent years, continuously variable transmissions (CVTs) have become a viable alternative, offering improved fuel economy but presenting unique lubrication challenges for optimal performance. Unlike traditional transmissions, CVTs use a pushbelt or chain between two variable-diameter pulleys, enabling an infinite number of gear ratios.
New transmission designs have unique lubrication needs that require specific characteristics. As more gears are incorporated, efficiency increases, but smaller clutch packs and reduced clutch plate surface areas necessitate ATFs that provide a precise balance of frictional properties.
Key lubricant characteristics include
Proper clutch heat transfer and wear protection.
Compatibility with torque converter lockup clutches for significant efficiency gains.
Incompatibility between ATF friction properties and lockup clutch materials can cause shudder and negatively impact drivability. Achieving these friction requirements necessitates a delicate balance of friction modifier additives, stabilized by a robust combination of antioxidants and specially engineered lubricant technology for smooth vehicle launches and shifting.
Idemitsu collaborates with individual OEMs to engineer technologies that meet these precise lubricant property requirements.
