KINEMATIC VISCOSITY ( P25, D 445, IP 71, ISO 3104)

Viscosity can significantly affect the lubricating property of the fuel and can have an influence on fuel pump service life and injector system. The viscosity of fuels at low temperature is limited to ensure that adequate fuel flow and pressure are attained under all operating conditions and that fuel injection nozzle and system controls will operate down to design temperature conditions. KV is a measure of the resistive flow on a fluid under gravity, the pressure head being proportional to the density, of the fluid: for gravity flow under a given hydrostatic head, the pressure head of a liquid is proportional to its density,
