FIELD: engines and pumps.
SUBSTANCE: device comprises the housing 1 with the measuring chamber 2 formed by the discharge solenoid valve, the injectors 5 and the plunger 6 with the return spring 7; the pick-off assembly representing an elastic plate 10 with strain gauges 11 and 12 adhered thereon, connected in a bridge circuit; the analog-to-digital converter 15 connected to the computer 13 and via the amplifier 14 to the pick-off assembly; the electronic unit 16 connected to the solenoid valve. The device is equipped with the safety valve 3. The housing 1 of the device is equipped with the limit stop 30 of the plunger 6.
EFFECT: invention improves the accuracy of fuel supply irregularity measurement by increasing the speed of the plunger separation from the measuring device housing due to eliminating the plunger rim sticking to the measuring device housing.
