Abstract Ducted fuel injection (DFI) is a cutting-edge technology for boosting the air-fuel mixture quality of heavy-duty diesel engines. The present study employs ducts with different lengths and inner diameters to investigate the diesel macroscopic spray characteristics of DFI spray by Schlieren optical technique and compares them with a free spray.

Abstract Enhancing mixture preparation upstream of the premixed autoignition zone is a solution to reduce soot emission formation in compression ignition engines. With this aim, in recent years, Ducted Fuel Injection (DFI) concept has been developed: DFI is based on the idea of injecting the fuel spray through a small cylindrical pipe within the ...

A Computational Investigation of Engine Heat Transfer with Ducted Fuel Injection
International Journal of Engine Research, 2023Ducted fuel injection (DFI) is an innovative method that curtails or prevents soot formation in direct-injection compression-ignition engines. DFI uses a simple duct, positioned outside each injector hole, facilitating the fuel/charge gas mixing before ignition.

An optical investigation on spray macroscopic characteristics of ducted fuel injection
Experimental Thermal and Fluid Science, 2019Abstract Ducted fuel injection (DFI) spray is a new spray method that mimics Bunsen burner and has shown a great potential to reduce soot emissions and improve thermal efficiency for heavy-duty diesel engines. But the mechanism has not been revealed clearly.
