共轨喷油器驱动电路的试验研究

An Experimental Study on the Driver Circuit of Common-rail Injector

在一种灵活的共轨喷油器驱动电路的基础上,重点研究了不同的充电速率、放电速率和保持电流对共轨式燃油喷射系统的瞬态响应、一致性、最小油量控制和多次喷射的影响,为实现共轨式燃油喷射系统的上述各种特性综合最优提供依据。

Based on a flexible driver circuit for common-rail fuel injector, the effects of different charge rates, discharge rates and holding currents on the transient response, consistency, minimum injected fuel control and multiple injection of common-rail fuel injection system （CRFIS） are emphatically studied, providing a basis for achieving overall optimization on various characteristics of CRFIS.
