Abstract:
1. A device for separating fuel components comprising: a separating membrane that separates high-octane fuel components from un-separated fuel; a heater that heats said un-separated fuel; a first temperature sensor positioned upstream from said heater, the first temperature sensor detects a first temperature of said un-separated fuel; a second temperature sensor positioned downstream from said heater, the second temperature sensor detects a second temperature of said un-separated fuel after being heated by the heater; and a pressure apparatus that pressurizes said un-separated fuel; wherein said un-separated fuel is heated by said heater and said un-separated fuel is pressurized by said pressure apparatus such that a state of said un-separated fuel is changed to a mixed gas phase and liquid phase state of a gas weight ratio from 50% to 95% before coming into contact with said separating membrane, said gas weight ratio of said un-separated fuel is estimated on the basis of said second temperature of said un-separated fuel detected by said second temperature sensor and a pressure of said pressurized un-separated fuel; wherein an amount of heat applied by said heater is estimated on the basis of said estimated gas weight ratio of said un-separated fuel and a difference between said second temperature after said heater and said first temperature before said heater, and it is determined that the current un-separated fuel has a molecular weight heavier than that of a normal fuel when the estimated amount of heat applied by said heater is larger than an actual amount of heat applied by said heater.
