Abstract :
For the evaluation of the condition of automotive engine oil, the oil´s viscosity is an important parameter. Using microacoustic viscosity sensors, an oil viscosity measurement can be performed on-board. In this contribution we outline the basic requirements and review the suitability of microacoustic sensors for this application.
