Abstract

The proper exchange of automobile engine oil leads to the saving of resources as well as the safe maintenance of automobile engine. In this paper, we designed the capacitive sensor to monitor changes in the dielectric constant of the engine oil and we fabricated the sensor by using semiconductor fabrication technology. Experiments have been carried out with the fabricated sensor equipped on oil chamber using a typical fully-formulated oil. The capacitance of sensor increased at about 3 percent per 1,000km.
