Abstract
A fuel tank processing apparatus includes a first valve, a discharge path, a second valve, and a calculation controller. The first valve is disposed in a fuel tank that stores fuel. The first valve communicates with outside of the fuel tank through the discharge path. Gas discharged from the fuel tank flows through the discharge path. The second valve is disposed in the discharge path. The calculation controller is configured to adjust an opening degree of the second valve. The calculation controller is configured to adjust the opening degree of the second valve based on a change in condition of the fuel tank when the second valve is opened.
Claims19
A fuel tank processing apparatus comprising:
- a first valve disposed in a fuel tank that stores fuel;
- a discharge path through which the first valve communicates with outside of the fuel tank and through which gas discharged from the fuel tank flows;
- a second valve disposed in the discharge path;
- and
- a calculation controller configured to adjust an opening degree of the second valve, wherein the calculation controller is configured to adjust the opening degree of the second valve based on a change in an internal pressure of the fuel tank when the second valve is opened, and
- wherein the calculation controller is configured to calculate a pressure drop in the discharge path based on an amount of the fuel in the fuel tank, a time spent for depressurizing the fuel tank, and a degree of reduction in an internal pressure of the fuel tank.
A fuel tank processing apparatus comprising:
- a first valve disposed in a fuel tank that stores fuel;
- a discharge path through which the first valve communicates with outside and through which gas discharged from the fuel tank flows;
- a second valve disposed in the discharge path;
- and
- circuitry configured to adjust an opening degree of the second valve,
- wherein the circuitry is configured to adjust the opening degree of the second valve based on a change in an internal pressure of the fuel tank when the second valve is opened.
