Abstract:
The aim of the current paper is to link nozzle geometry, and its effects on spray characteristics, with combustion characteristics in the chamber of IC engine. The combustion and formation in a diesel engine is governed mainly by spray formation and mixing. Important parameters governing these are droplet size, distribution concentration and injection velocity. Smaller orifices are believed to give smaller droplet size, even with reduce injection pressure, which leads to better fuel atomization, faster evaporation and better mixing. For this purpose, three 6-hole sac nozzles, with different orifices degree of concavity, have been used. The analysis of all the results allows linking nozzle geometry, spray behavior and combustion development. In particular, CH-radicals have shown to appear together with vapor spray, both temporally and in their location, being directly related to nozzle characteristics.
