| Abstract(E) | In a direct-injection gasoline engine, strict control of pollutant emissions at cold start is a critical point to comply with new regulations, and the fuel film formed by spray impingement on the piston wall is closely related. In this context, the purpose of this study is to clarify the liquid film formation process of spray impinging on a low temperature wall. Total internal reflection laser induced fluorescence (TIR-LIF) method was applied to the liquid film formed by wall impingement gasoline spray. TIR-LIF method can measure the fluorescence from liquid film without the influence of the spray droplet. The fluorescence intensity from the liquid film depends on the film thickness and temperature. In this paper, a new analytical method that models the heat transfer phenomena related to the liquid film was developed. Using those methods, the liquid film formation process was evaluated. |
