摘要： A method, comprising indicating an amount of a residual fuel in a fuel tank based on an initial rate of change of a fuel tank pressure during a refueling event. The initial rate of change of fuel tank pressure is proportionate to the amount of vapor dome space within the fuel tank, and thus proportionate to the amount of residual fuel left in the fuel tank. In this way, the fuel tank fill level may be accurately quantified, even during cases where the fill level indicator experiences degradation.

摘要： An evaporated fuel processing apparatus includes a valve between a canister and a fuel tank, and adsorbs evaporated fuel by the canister during fuel filling, and introduces into an intake air line of an internal combustion engine and processes the evaporated fuel while the internal combustion engine is operating. A diagnostic apparatus includes: a pump for pressurizing a system including the fuel tank and the canister; and a pressure sensor for sensing an internal pressure of the system. The diagnostic apparatus diagnoses whether or not leakage is present, based on a change in the internal pressure of the system from a pressurized state, wherein the pressurized state is a state pressurized to a predetermined pressure for diagnosis that is higher than a tank pressure at start of diagnosis; and maintains the fuel tank in the pressurized state by closing the valve after termination of the diagnosis.

摘要： An evaporated fuel processing apparatus includes a valve between a canister and a fuel tank, and maintains the fuel tank in hermetic state by closing the valve while a vehicle is stationary, and adsorbs evaporated fuel by the canister by opening the valve during fuel filling, wherein the evaporated fuel occurs in the fuel tank. A diagnostic apparatus includes: a pump connected to a canister-side region with respect to the valve, and configured to pressurize a system of the canister and the fuel tank; and a pressure sensor for sensing an internal pressure of the system. The diagnostic apparatus starts pressurization by the pump with the valve closed; brings the system into a pressurized state by opening the valve with a delay after the start of pressurization; and performs a leakage diagnosis based on a change in the internal pressure of the system from the pressurized state.
