Abstract: An efficient method of boxing fuel injectors with a good yield where a predetermined quality is secured in a predetermined number of fuel injectors forming a set for one engine, that is, a method of boxing fuel injectors, a first number of which are scheduled to be mounted in an engine, in a single box in a second number larger than the first number, provided with a step of measuring a characteristic value for the second number of fuel injectors, wherein when the first number of the characteristic values forms a set, the number of combinations of the characteristic values where a total value of this one set's worth of the characteristic values becomes a first management value or less when selecting one set's worth of the characteristic values from the second number of the characteristic values, is defined as the “number of good part combinations”, and the number of possible combinations of one set's worth of the characteristic values is defined as the “number of possible combinations”, the fuel injectors bein

Abstract: A liquid measurement apparatus is configured to measure an amount of liquid flowing from a measured object. The apparatus includes a passage member having a measurement passage being connected to the measured object at one end. The measurement passage is filled with liquid. The apparatus further includes a closed vessel, which is connected to an other end of the measurement passage and filled with saturated vapor of the liquid. The apparatus further includes an analyzer. The liquid filled in the measurement passage contains a bubble, which is movable in accordance with change in amount of the liquid in the measurement passage. The analyzer is configured to calculate a travel distance of the bubble and configured to measure the amount of the liquid flowing from the measured object based on the calculated travel distance.
