Modeling of Diesel Spray Impinging Behavior on Oil Film (Third Report)
Oil dilution is a serious problem in post injection. When constructing a model that predicts oil dilution, handling of lubricating oil film in wall impingement model is difficult. Therefore, the authors investigated the influence of the lubricating oil film thickness on the fuel deposition amount, using the Laser Induced Fluorescence Method. As a result, it was found that when the non-dimensional film thickness (δₙₒₙ= δₒᵢₗ/dᵢₙ, δₒᵢₗ : lubricating oil film thickness, dᵢₙ : fuel droplet diameter) is less than 0.24, that is, when the lubricating oil film thickness is less than 3.4 μm, the fuel deposition amount is same to that of the dry wall.
