Computational Analysis of Spray Angle Effects on Combustion and Emissions in Methane‐Diesel Dual‐Fuel Engine

Energy Science &Engineering, Volume 14, Issue 3, Page 1100-1112, March 2026.
This study concluded that wider spray angles produce wall impingement and greater unburned hydrocarbons in methane‐diesel dual‐fuel engines, whereas 110° balances efficiency and emissions. ABSTRACT A diesel methane dual fuel engine appears as a potential means for lowering emissions while retaining useful thermal efficiency.
