Development of Acoustic Emission Viscosity Model for Measuring Engine Oil Viscosity Relationship with Engine Oil In-Service Age

摘要

Monitoring the viscosity of diesel engine oil is very important as it affects the performance of engines. In this study, the AE signals are applied for measuring the viscosity of engine oil which is affected by the increase of the age of the in-service duration. AE signals are generated in the sliding zone of the piston as well as on the engine oil surface, because the signal is very sensitive to the viscosity of the engine oil. The AE signals can be translated into AE energy by using the Time Domain Analysis. The value of the viscosity will be assessed from the AE energy by applying certain mathematical equations. This study shows that the AE viscosity model is applicable to determine the viscosity of the engine diesel oil.
