METHOD FOR DETERMINING ENGINE LUBRICATING OIL CONDITION

METHOD FOR DETERMINING ENGINE LUBRICATING OIL CONDITION

Activation energy, W, is determined from oil conductivity measurements to thereby provide engine oil condition from a known relationship between viscosity and W. Changes of W at a given temperature as the oil ages are reflective of changes in viscosity of the oil at the same given temperature, where...

description Activation energy, W, is determined from oil conductivity measurements to thereby provide engine oil condition from a known relationship between viscosity and W. Changes of W at a given temperature as the oil ages are reflective of changes in viscosity of the oil at the same given temperature, wherein changes in W at different temperatures are reflective of changes of viscosity at those respective temperatures as the oil ages. To determine viscosity, the temperature dependence of the oil's conductivity is measured to deduce the value of W at a given temperature. W is monitored as the oil ages. W may also be determined through the ratio of the oil conductivities at two different temperatures by techniques well known in the art by which the viscosity may be determined as the oil ages.
