Due to the advancement of engine performance, large volumes of oil circulate within a narrow internal space of passenger car engines. This phenomenon often leads to oil foaming and aeration problems. In this study, we developed a method for predicting the rate of engine oil aeration from specific engine parameters and running conditions. Engine tests show that the rate of oil aeration is stable throughout the process between bubble release from the oil surface and aeration. Additionally, bubble size affects its release rate from the oil surface. Utilizing both of these assumptions, our prediction method calculates aeration rate by evaluating bubble number and size.
