EVAPORATIVE EMISSIONS FUEL SYSTEM

摘要

An engine includes a fuel tank with a fuel tank body defining an internal fuel tank volume for containing a fuel, a vent conduit integrally formed with the fuel tank body, and an air cleaner system including an air cleaner housing defining an internal air cleaner volume. The vent conduit extends between an inlet aperture and an outlet aperture. The inlet aperture is in fluid communication with the internal fuel tank volume. An opening is formed in the air cleaner housing and the vent conduit extends through the opening. The outlet aperture of the vent conduit is positioned within the internal air cleaner volume and the vent conduit provides fluid communication between the internal fuel tank volume and the internal air cleaner volume.
