Analysis of the ducted fuel injection concept for compression-ignition engines

Nilsen, Christopher W.; Mueller, Charles J.

Ducted fuel injection (DFI) is a technique for lowering emissions (primarily soot emissions) from high-efficiency compression-ignition (CI) engines, as well as other devices employing the direct injection of fuel into a combustion chamber. The DFI concept was inspired by the cleaner burn that is created by premixing fuel and air in the tube of a Bunsen burner, which was created to reduce soot production common in burners of the period as stated by Kohn [American Chemical Society, 1949].
