Cylinder Wall Drying of Oils and the Relation to Cold Engine Wear 670940
Measurements were made of the rate of drying of lubricating oil on the cylinder wall of a cold running gasoline engine. Between jacket water temperatures of about 50–100 F drying rate was roughly constant, depending only on the rate of oil circulation to the cylinder. At lower temperatures the drying rate decreases. These results supply a means of estimating the rate of oil circulation to and from the cylinder wall. Conventional oil compounding holds water into the oil and as a result the oil remains wet during its stay on the cylinder. The possible relation of these observations to acid collection and engine wear is discussed.
