ABSTRACT:
A fuel separation apparatus includes a fuel tank storing the material fuel fed to a separation membrane, a fuel tank storing a separated low-octane fuel, and a fuel tank storing a separated high-octane fuel. An electronic control unit of the separation apparatus calculates the flow rate (amount of formation) of the high-octane fuel flowing into the high-octane fuel tank based on a change in the liquid level in the tank and on the amount of fuel fed to an engine from the tank, and so judges that an abnormal condition is occurring due to the breakage of the separation membrane when the amount of forming the high-octane fuel is larger than a predetermined upper limit value and that an abnormal condition is occurring due to a drop in the function of the separation membrane when the amount of formation is smaller than a predetermined lower limit value.
