Assessment of Lubrication Conditions in a Big-End Bearing by Temperature Measurements-Correlation with High Shear Viscosity

When dealing with overall engine performance, engine journal bearings are recognized to be of major importance. Their lubrication can be critical, especially with increasing sump temperatures, as it is already a high energy consuming process.

Of all the measurements possible to control engine bearing performance, temperature measurements are the most advantageous and simplify the recording process.
