  • Test system and method for the mutual solubility of biomass-based blended fuel
    Patent number: 11828706
    Abstract: The present invention relates to a test system and method for a biomass-based blended fuel. The system comprises a feeding device, a mixing tank, a light-sensing device, and a control device; the feeding device comprises at least two fuel bottles; the fuel bottle is connected to the mixing tank by means of an oil pipe; the correspondingly connected oil pipe of each fuel bottle is provided with a flow valve; the light-sensing device comprises a laser disposed above the mixing tank, a light-reflecting mechanism disposed at the bottom in the mixing tank, and a light-sensing mechanism disposed at one side of the light reflecting mechanism; the output end of the light-sensing mechanism is signaled with the input end of the control device; the input end of the laser and the input end of the flow valve is separately signaled with the output end of the control device.
