Abstract
A fuel supply apparatus includes a material fuel tank, a separator, a condenser, a first fuel tank, and a first storage device. The material fuel tank is to store a material fuel. The separator is to separate the material fuel supplied from the material fuel tank into a first fuel and a second fuel. The condenser is to condense the first fuel supplied from the separator through a primary-order recovery passage. The first fuel tank is to store the first fuel supplied from the condenser through a secondary-order recovery passage. The first storage device is provided in the secondary-order recovery passage to temporarily store the first fuel supplied from the condenser.
Claims5
A fuel supply apparatus comprising:
- a material fuel tank to store a material fuel;
- a separator to separate the material fuel supplied from the material fuel tank into a first fuel and a second fuel, the first fuel containing a larger amount of high-octane component than an amount of high-octane component of the material fuel, the second fuel containing a larger amount of low-octane component than an amount of low-octane component of the material fuel;
- a condenser to condense the first fuel supplied from the separator through a primary-order recovery passage;
- a first fuel tank to store the first fuel supplied from the condenser through a secondary-order recovery passage;
- a first storage device provided in the secondary-order recovery passage to temporarily store the first fuel supplied from the condenser;
- a vacuum pump provided to a first fuel vapor passage linking the condenser and the first fuel tank to suction and supply fuel vapor generated by vaporization of the first fuel from the condenser to the first fuel tank;
- a control device configured to control operations of the vacuum pump;
- and
- a flow adjustment mechanism to adjust flow of the first fuel, downstream of the first storage device in the secondary-order recovery passage and upstream of the first fuel tank,
- wherein the control device is configured to control operations of the flow adjustment mechanism and the vacuum pump so that
- a primary-order state in which the first storage device and first fuel tank are shut off by the flow adjustment mechanism and in which the condenser is decompressed by operations of the vacuum pump, and
- a quaternary-order state in which the first storage device and first fuel tank are linked by the flow adjustment mechanism and in which decompression of the condenser of the vacuum pump is stopped,
- are realized in sequence.
