VAPOR PROCESSING APPARATUS
First Claim
1. A vapor processing apparatus comprising:
- a tank-inner-pressure detector configured to detect tank inner pressure of a fuel tank retaining fuel to be supplied to an engine;
an atmospheric-pressure detector configured to detect atmospheric pressure;
a canister configured to adsorb and collect vapor generated in the fuel tank;
a control valve disposed in a vapor channel connected to the fuel tank; and
a controller configured to control opening and closing of the control valve based on a value detected by the tank-inner-pressure detector, a value detected by the atmospheric-pressure detector, and a correction value learned in advance, when in a predetermined state.

Abstract
A vapor processing apparatus includes a tank-inner-pressure detector, an atmospheric-pressure detector, a canister, a control valve and a controller. The tank-inner-pressure detector is configured to detect tank inner pressure of a fuel tank retaining fuel to be supplied to an engine. The atmospheric-pressure detector is configured to detect atmospheric pressure. The canister is configured to adsorb and collect vapor generated in the fuel tank. The control valve is disposed in a vapor channel connected to the fuel tank. The controller is configured to control opening and closing of the control valve based on a value detected by the tank-inner-pressure detector, a value detected by the atmospheric-pressure detector, and a correction value learned in advance, when in a predetermined state.
