* A mixture of the following base oil and a viscosity index improver (the ratio = 90:10) was evaluated.
Base oil properties: kinematic viscosity (100 °C); 4.31 mm2/s, kinematic viscosity (40°C); 20.3 mm2/s, Viscosity index: 121
The viscosity change with temperature is smaller as the viscosity index value heightens.
** Measured according to JASO M347-95 (sonic).
The shear stability is better as SSI lowers
Mechanism of Viscosity Index Improver (VII)
Figure 1 shows a schematic diagram of the dissolution state of VII and the viscosity behavior of lubricating oil.
When VII is not added [A, C in Figure 1], the viscosity changes significantly with temperature, so the viscosity of low-viscosity base oils falls outside the proper range at high temperatures and that of high-viscosity base oils at low temperatures. By adding VII to low-viscosity base oils, viscosity can be maintained in the proper range over a wide temperature range from low to high temperatures [ B in Figure 1].
This is because the solubility of VII in lubricating oil changes depending on temperature, and at high temperatures, the molecular chains of VII are extended and broadened, which significantly increases the viscosity of the lubricating oil, while at low temperatures, the molecular chains of VII are contracted and become small and rounded, which has a smaller effect on increasing the viscosity of the lubricating oil.
ACLUBE POUR POINT DEPRESSANT
Lubricating oils obtained by adding ACLUBE products to base oils have excellent fluidity even at temperatures below freezing point (Table 4).
