“…A third example of a suspension in which the particles interact with one another is found in used engine oil analyses. Kabel (1970) has demonstrated that, under extreme engine operating conditions, the viscosity of a lubricating oil can increase exponentially with time as shown in Figure 1, These data were obtained in an engine dynamometer experiment carried out under ASTM Sequence IIIC Test conditions (1973). Controlling the oil sump temperature at successively lower values delays the onset of the catastrophic viscosity increase, but not indefinitely.…”

of about 22 weeks with a continuous input of 0.075 ppm of N02. ConclusionsThe results of this work indicate that indoor control of NO2 can be achieved-by relatively simple and convenient means via the use of a zinc chloride coated copper-fiber filter in the air circulation system. Relatively long-lived and efficient removal can be achieved without adding excessive additional pressure-drop load to existing blowers or fans. The development of a design model is outlined for application purposes. It is envisioned that these filters will be of use in a number of industrial applications where NO2 concentrations in the ambient air exceed safe limits. Typical application sites might include foundry buildings, glass industry shops, etc.
