| Abstract(E) | This report presents the results of testing the oil-repellent and slip properties between engine oil and the substrate using molecular dynamics and particle methods. By applying molecular dynamics methods, a desk-based verification model was developed to predict the tendency of engine oil mist, which triggers deposit buildup on intake system components, to adhere. This enabled the selection of coatings effective in suppressing adhesion and the consideration of formulations for engine oil additives.In addition, the behavior of oil mist was visualized using the particle method, and the validity of the adhesion suppression effect was examined. |
