The invention discloses a pneumatic EFI dynamometer, which comprises a plurality of glass tube on the table and a clip for measuring EFI clamping device, the lower end of the glass tube check valve and recovery tank connected to the recovery tank and the liquid storage tank is connected through a one-way valve, under the liquid level and the pipeline for EFI inlet pipe connected into the liquid storage tank, the liquid storage tank with an air inlet and a pressure source connected. The flow of the working fluid is driven by the air pressure and the volume of the liquid storage tank is larger, and the pressure fluctuation of the working liquid is very small or the pressure is constant when the detection operation is carried out, and the detection accuracy can be ensured.
