Abstract: A fuel vapor recovery system for a fuel tank of a vehicle includes a vapor canister fluidly communicating with an interior chamber of the fuel tank to adsorb fuel vapor. The fuel vapor recovery system also includes a check valve adapted to be disposed in the fuel tank and adapted to be fluidly interconnected with the vapor canister and the fuel tank to allow one-way flow of fuel vapor from the interior chamber to the vapor canister.

Abstract: A method for improving vehicle battery state-of-charge (SOC) for initial vehicle customer delivery is disclosed. The method is focused on vehicle assembly plant practices and ensuring that battery discharge is minimized or eliminated during the vehicle assembly process. The method includes determining the available maximum percentage of duty cycle voltage output from the vehicle alternator and determining a minimum idle boost speed necessary to provide minimum discharge or positive charge to the battery when the vehicle's accessories are in the “on” state during vehicle assembly. The method further includes programming the vehicle's controllers to force the maximum percentage of duty cycle voltage output available and the minimum idle speed necessary to provide minimum battery discharge or positive charge during the earliest part of the vehicle life.
