Transmission oils based on KEMAT polybutenes enhance powertrain performance
Transmission oils formulated with polybutene provide the following benefits: bright stock replacement; lower smoke, exhaust blocking and deposits; help to improve low-temperature performance; high temperature bulk viscosity; thermal and oxidative stability.
To shift the engine power to the driving wheels, automotive vehicles need a power transmission system (powertrain). Within the powertrain there are other parts including a gear system, clutch and differential mechanisms. There are four main types of gear systems: mechanical, semi-automatic, automatic, and hydrostatic. And within these gear systems there are different kinds of gears, eg spur helical, straight bevel, spiral bevel, low/high offset hypoid, and planetary.
Powertrain systems need transmission oils to reduce friction in gears and bearings. Synthetic oils used in lubricating automotive gears provide several advantages: improved oxidative stability; improved viscometrics at high temperature (high VI); better low-temperature properties; lower volatility.
