摘要： A method for manufacturing a cylinder interior fuel injection valve and an apparatus for adjusting a fuel injection amount used therefor may sufficiently cope with a fluctuation in fuel pressure or combustion gas pressure that would occur in an actual engine. According to this manufacturing method, a position of an adjuster is adjusted (step 110), a fuel injection amount is measured (step 111), and it is judged whether or not the measured value of the fuel injection amount falls within a range of a rated value (step 112). Then, if the fuel injection amount is out of the range of the rated value, the process is returned back to the step 110, and if it falls within the range of the rated value, the process shifts to a subsequent step 113. Subsequently, a spring force of a valve closing spring is measured (step 113), and it is judged whether or not the measured value of the spring force falls within a control range (step 114). Then, if the spring force is out of the control range, the process is returned back to the step 110, and if it falls within the control range, the adjuster is fixed (step 115) and the process shifts to a next step.
