PURPOSE:To prevent an explosion from being caused by the injection fuel within a vessel by a method wherein an inactive gas is left induced in a testing vessel of the testing device of the fuel injection valve. CONSTITUTION:The testing vessel 11 is provided with the fuel injection valve 12 through which the fuel in a tank 13 is unjected. The amount of the fuel injected is observed through observation windows 5 and then, the fuel returns to the tank 13 through a gas-liquid separator 23. The inactive gas is induced from a bomb 16 into the vessel 11 to cause the explosion to be checked. The gas is exhausted by a vacuum pump 20 through a pressure setting valve 21 when the gas pressure reaches a fixed value. |
