<p><P>PROBLEM TO BE SOLVED: To provide an efficient method for boxing fuel injection valves with a good yield securing predetermined quality in a predetermined number of fuel injection valves constituting a combination for one engine. <P>SOLUTION: In the method for boxing a second number which is greater than a first number of the fuel injection valves which the first number of are to be installed on one engine in a box, a step S1 measuring a characteristic value of second number of fuel injection valve are measured is provided, the first number of the characteristic values form a group, the combination number of the characteristic value keeping total value of a group of the characteristic values at first control value or less is defined as good part combination number when a group of the characteristic values are selected from the second number of characteristic values, and the fuel injection valves are boxed in one box to keep the good part combination number becomes more ratio than fourth control value to an arbitrary combination member or less when the arbitrary combination number of a group of the characteristic values is defined as the arbitrary combination number. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
