Abstract
A vaporized fuel processing apparatus has a canister capable of adsorbing vaporized fuel generated in a fuel tank, a closing valve provided in the vapor path connecting the canister and the fuel tank and having a valve seat and a valve movable portion, a pressure sensor configured to detect inner pressure of the fuel tank, and an electric control unit. The electric control unit is configured to set a learning value that is an axial distance between the valve seat and the valve movable portion at a valve opening start position at a fail-safe value such that the closing valve is in the valve closing state when the inner pressure of the fuel tank decreases by less than a predetermined value after repeating a stroke control process more than predetermined times.
