Peter W. Jacobs - Flemington NJ, US

International Classification:

G01N 27/06
G01N 33/28

Abstract:

Systems and methods for real-time monitoring of electrical discharge events across a tribological contact are provided. The systems comprise a signal generator, a test device comprising a tribological contact, a reference device and a signal comparator. The systems recognize changes between states where electrical discharge across a tribological contact does or does not occur and produce distinct output signals for each state and, further, may maintain a count of how often such events occur.

Abstract:

A method for improving wear control, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and (i) at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) or (ii) a mixture of at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) and at least one detergent (i.e., an alkali metal or alkaline earth metal salt of an organic acid, or an alkali metal or alkaline earth metal salt of an inorganic acid, or an alkali metal or alkaline earth metal salt of a phenol, or mixtures thereof (e.g., calcium salicylate and/or magnesium sulfonate)), as a minor component. The lubricating oils are useful in internal combustion engines.
