抄録

In order to study the effect of fuel injection rate shaping on spray combustion, an electronically controllable fuel injection system was developed. In this system, the arbitrary injection rate shaping was obtained by controlling the movement of nozzle needle directly with piezoelectric actuator while the fuel pressure was maintained its constant injection pressure. By using this injection system, fuel was injected into the pressure chamber with three types of fuel injection rate shaping with different slope of injection rate rise. From the results of visualizations of non-evaporating spray, it was found that the slope of injection rate rise made great influences on the spatial and temporal fuel distributions and spray temporal evolution. Moreover, it was shown that, though there was no great difference in spray angle in low injection rate, spray angle by lift control injection was larger than that by pressure control injection in high injection rate.
