Ducted fuel injection technology, an advanced spray combustion method, enhances fuel-air mixing and reduces emissions, particularly with low-carbon fuels like methanol. This review highlights a key discovery: ducted fuel injection improves atomization and fuel-air interaction through the entrainment of ambient air at the duct inlet and shear-induced vortices at the outlet. These mechanisms promote secondary atomization, improving combustion efficiency and lowering incomplete combustion emissions. The study synthesizes recent advances in ducted fuel injection technology, focusing on spray characteristics, air entrainment, and combustion diagnostics, while also exploring engine integration and potential applications. By aligning ducted fuel injection with global carbon neutrality goals, the review underscores its potential to drive the transition to low-emission, high-efficiency transportation dynamic systems.
