Abstract :
Measurements of the ultrasound propagation speed in engine oils as a function of temperature in the range from 8 degC to 153 degC were performed. The data obtained are important for the validation and for the uncertainty estimation of the ultrasound- based oil-filling level measurement systems recently developed for car engines.
