  • Adjusting method of fuel injection system
    Patent number: 6354276
    Abstract: An adjusting pipe is being inserted into a housing while increasing an electric current frequency for a coil to control a fluid flow amount being constant. Since the electric current frequency is increased while keeping the fluid flow amount constantly, there is no need to wait until the flow amount becomes stable. Since both an insertion amount of the adjusting pipe and the frequency of the electric current supplied into the coil are simultaneously, continuously, and dynamically changed and adjusted, an adjusting time thereof is reduced.
