Abstract
PURPOSE: To reduce an error of measurement, which is caused by the volume compression due to an increase of pressure, by injecting fuel oil from an injector to be measured into the injection chamber after previously increasing the pressure in the injection chamber up to a fixed level.
CONSTITUTION: The motor 100 is connected to the shafts 101W104 to drive the cams 200a, 300, 400a and rotary pulse generator 9. With the first rotation of the shaft, the valve 303 closes the exhaust oil passage 304. With the next rotation of the shaft, the injection pump 400 injects the fuel oil into the injection chamber 5, pressure in the injection chamber 5 increases up to a fixed level and the piston 601 ascends. A signal corresponding to the displacement of the piston 601 is stored in the arithmetic unit 8 by the pulse 901 produced by the rotary pulse generator 9. With the subsequent rotation of the shaft, the pump 200 to be measured injects the fuel oil, the piston 601 moves and the corresponding sugnal is stored in the arithmetic unit 8 by the pulse 902. The quantity of injection of one time is computed from the difference between both stored signals. In this way, an error of measurement can be reduced.
