THE RELATIONSHIP BETWEEN ENGINE OIL VISCOSITY AND ENGINE PERFORMANCE--PART 5 AND PART 6

Twelve symposium papers explore the effect of engine lubricant viscosity on engine performance. Topics include the use of a Couette high-shear-rate viscometer in measuring the viscosity of engine lubricants, the assessment of shear stability methods for European engine oils, low-temperature starting and pumpability requirements of European automotive engines, the effect of engine oil viscosity on low-temperature cranking and starting and on fuel economy, cold starting and oil pumpability (evaluation of new and used oils in gasoline engines), measurement of the ring to liner oil film thickness in a Caterpillar 1-G diesel engine, laboratory testing of fuel efficient oils, and the prediction of low-temperature engine oil pumpability with the Mini-Rotary viscometer. Also discussed are the use of a radiometric test to determine lubricant effect on journal bearing load capacity, the development of a high-shear-rate capillary viscometer for engine oils, the determination of engine oil frictional characteristics by engine friction and viscosity measurements, and low-temperature viscosity characteristics of used engine oils.
