Combustion Characteristics of Diesel Methanol Blended Fuel Ship Engines

Abstract With increasingly stringent fuel emission control in some river traffic zones and inland waters, this paper addresses the problem of substandard diesel emissions, relying on theoretical basis numerical simulation engine in-cylinder combustion. The combustion characteristics diesel-water-mixed methanol blended are simulated analyzed based AVL FIRE software. model was established, changes pressure, temperature, heat release rate, concentration were investigated for D85W10, D85W15, D85W20 blends respectively, which compared with diesel. results show that as proportion water mixture increases, temperature gradually pressure slightly decreases, rate does not change much, NO Soot emissions decrease.
