Abstract

In this study, the oil degradation measuring for integrated sensor of drain valve was fabricated. A sensor used in the experiments was integrated with drain valves and installed in oil pan without requiring additional space. As a result of the experiments, the capacitances changed with two inflection points in accordance with an after in mileage. The first inflection point indicated the exhaustion of oil additives, and after the second inflection point, the oil degradation was completed, which increased the viscosity and disabled the functions of oil. Thus, this section was determined as the time of oil exchange.
