SYSTEM AND METHOD FOR TESTING MISCIBILITY OF BIOMASS-BASED BLENDED FUEL

摘要

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 are separately signaled with the output end of the control device. According to the present invention, the structure is simple, an ECU control device is used to carry out numerical control on each mechanism, and the miscibility of a blended fuel as well as a change relation between the miscibility of the blended fuel and an ambient temperature can be rapidly measured by using the principle that the blended fuel has different refractive indexes in a miscible state and in a stratified state (i.e., an immiscible state).
