Fuel vapor control apparatus |
摘要 |
A fuel vapor control apparatus determines whether the concentration of fuel vapor in a space above the surface of liquid fuel in the fuel tank is less than a predetermined concentration. When the concentration of fuel vapor is less than the predetermined concentration, the concentration of fuel vapor in the fuel tank is increased and, when the concentration of fuel vapor exceeds the predetermined concentration, the increase of the concentration of fuel vapor is stopped. Therefore, an amount of fuel flowing out of the fuel tank can be reduced while using a reduced amount of energy.
