Abstract
<PICT:0917997/III/1> The rate of consumption of lubricant by an internal combustion engine is determined by dissolving in the lubricant a known concentration of a metallic compound, extracting a known fraction of the exhaust stream and entraining this in a flame, and then photometrically determining the intensity of light generated by the flame of a wavelength characteristic of the metal introduced into the lubricant by the compound. Sodium mahogany soap is dissolved in the lubricating oil of an engine and a sample of its exhaust products is introduced into the flame of a gas burner. The intensity of light from the flame corresponding to sodium is measured in terms of the intensity of the light corresponding to a substance not normally contained in the exhaust products, such as lithium, by the arrangement shown in which the reference signal corresponding to the lithium intensity is variable for setting-up purposes. The device is calibrated by measurements on an engine of known characteristics.
