PROBLEM TO BE SOLVED: To provide an injection amount measuring device and an injection amount measuring method capable of performing an accurate measurement of an injection amount for every cycle even if a small injection amount is measured at the time of fuel injection amount measurement.SOLUTION: An injection amount measurement device 10 comprises discharging valve information memory means 31 for storing the number of opened discharging valves and a changing-over injection amount for changing over the number of valves while being adapted to each other, and is operated in such a way that an injection amount based on a displacement amount detected by the injection amount detector 11 is calculated, the number of opened valves of the discharging valves of the injection amount detector 11 is taken on the basis of the discharging valve information memory means 31 in response to the calculated injection amount, a valve opening time of the opened discharging valves is calculated on the basis of the opened valve taken, and an opening or closing of the discharging valves is controlled. Further, the injection amount measurement device 10 controls opening or closing of the discharging valves on the basis of the different changed-over injection amount in one case that the injection amount is increased and the other case that the injection amount is decreased.SELECTED DRAWING: Figure 1 |
