‘ Technical experts at Shell are working with OEMs with prototype transmissions running in order to optimise or modify existing fluid technology ’
For example , UTTOs may need to be introduced into loader transmissions and toroidal drives require so-called traction fluids .
Reducing power losses in offhighway transmissions and drive axles can result in extra requirements for
friction characteristics and friction durability of different transmission oils ( Cat . TO-4 type and UTTO type ).
Lower viscosity oils will help improve fuel economy when applied in engines and reduce power losses in transmissions and axles .
In hydraulic systems viscosity should be high to provide good volumetric efficiency in pumps and motors and low to reduce churning and circulation losses . Most likely this compromise will lead to extreme shear-stable high VI fluids of both industrial type hydraulic oils ( DIN / ISO ) and mobile hydraulic oils ( Cat . TO-4 and UTTO ).
