燃油喷射系统是控制发动机燃烧的关键部件,而对柴油机燃烧影响最大的因素是喷油规律。喷油器作为燃油系统的一个末端组件,它结束供油规律的形成过程,直接将燃油喷散雾化,并借助于空气涡流将燃油喷注以与燃烧室最佳配合的方式喷入燃烧室。因而在组织发动机燃油供给过程中,喷油器在一定程度上决定了喷油过程的最终参数,如喷油压力、喷油时刻、喷油持续时间和喷油规律 Fuel injection system is to control the engine combustion of key components, and diesel combustion is the most important factor in the fuel injection. Fuel injector as an end of the fuel assembly system, which ends the formation of the law of fuel supply, the fuel atomization directly spray, and by means of air vortex fuel injection with combustion chamber with the best way to spray into the combustion chamber . Thus in the process of organizing the engine fuel supply, the injector determines to a certain extent the final parameters of the injection process, such as injection pressure, injection time, injection duration and injection law
