Abstract

See full text

The vertical shaft fuel tank cap with a charcoal canister includes a fuel tank inner cap and a fuel tank outer cap. A hollow room or cavity with an upper opening is disposed in the center of the fuel tank inner cap. The fuel tank outer cap is above the fuel tank inner cap. The ventilating cap or vent cap is disposed in the cavity and divides the cavity into a filling cavity and a containing cavity. The air outlet leading the fuel vapor to the containing cavity is on the bottom of the containing room. The air passageway is between the outer walls of the vent cap and an inner wall of the containing cavity. The fuel-absorption substrate is disposed in the filling cavity. The filtering performance of charcoal powder can be enhanced since it is exempted from long-time fuel soaking.
