| Principles of Separation / Coalescence |
| Separating oil or solvents from water by mechanical means involves the application of some basic physical
principles. First, oil and water are not soluble in each other. Even so called soluble oils are really an emulsion not
a true solution. Second, water is denser than oil or petroleum based solvents. These properties tend to
result in separation naturally unless other factors interfere. ...More |

| Measuring Bearing Oil Film Thickness |
| The relationship between high temperature engine oil viscosity and its load carrying capability is not well
established. A new test method now offered at Southwest Research Institute measures the bearing oil film thickness
(BOFT) of lubricants in a fired engine under various operating conditions. ...More

Exhaust has less soot, due to advances in engine design and electronics.
Some improvement is due to cleaner burning, and some because soot is put
into oil rather than being blown out the stacks. ...More |
