Abstract

Atomization speed of diesel fuel injected from 8-hole nozzle is faster than that of 7-hole nozzle because the hole diameter of 8-hole nozzle is smaller than that of 7-hole nozzle. But both insufficient distance between the fuel sprays and short penetration of injected sprays through 8-hole nozzle hole cause many harmful effects on combustion. In this study, we installed the 8-hole injectors to diesel 2.0 liter class engine, and optimized in-cylinder swirl and penetration via selecting and matching proper cylinder head and combustion bowl. Through this process, we found out the performance and emission potential of 8-hole nozzle installed engine are better than those of 7-hole nozzle installed one.
