Abstract
A medium circulating apparatus of engine oil, which improves startability and warm up ability of an internal combustion engine, includes a microbubble generator that generates microbubbles and mixes the microbubbles into the circulating engine oil. Further, the medium circulating apparatus includes a medium temperature acquiring unit that acquires a temperature of the engine oil. The microbubbles are generated by the microbubble generator when the temperature of the engine oil is less than or equal to a predetermined value in order to decrease a viscosity, a heat conductivity, and a heat capacity of the engine oil in which the microbubbles are mixed.
