Abstract:

A new alternative (partially homogeneous) combustion process in diesel engines is proposed that provides changes in local values of the excess air coefficient and the temperature of the working substance in ranges lying beyond the area of the formation of nitric oxides and soot. The process is realized without significant changes in the serial construction. The developed 3D models of the diesel engine work process are realized in the CFD code of the AVL- FIRE software complex.

Keywords: diesel; 3D-transfer; partially homogeneous combustion; nitric oxides; soot.
