Appl. No.:

09/533333

Inventors:

Mahlon Richard Pachciarz - Grand Blanc MI
Gary Francis Stack - Fenton MI
Carlos A. Gutierrez - Grand Blanc MI

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B65D 142

US Classification:

220562, 220 414, 220 413

Abstract:

A plastic fuel tank including a hollow plastic tank body and a variable length plastic strut in the hollow tank body. A pair of flat plastic sheets are vacuum formed at a forming temperature in upper and lower mold cavities to the shape of upper and lower plastic shells. The plastic strut includes an upper foot, a lower foot, and a coupling means operable to support the upper foot on the lower foot for back and forth linear translation against a controlled resistance. With the mold cavities separated, the plastic strut is interposed between the upper and lower shells. The mold cavities are closed to form the hollow tank body by fusion bonding the upper and lower shells at respective attachment flanges on each. When the tank body thereafter cures and shrinks, the plastic strut is squeezed between the upper and lower shells against the controlled resistance of the coupling means to fusion bond the upper and lower feet of the strut to the shells. The strut expands and collapses during pressure and vacuum cycles in the tank body.

International Classification:

F16L 4100

US Classification:

285204, 285222, 2853824, 277644

Abstract:

A filler neck assembly includes a plastic fuel tank having a wall with an opening extending therethrough. The filler neck assembly also includes a filler neck tube extending through the opening in the fuel tank and having an annular stop flange projecting radially outward from the filler neck tube outside the wall and an annular lock flange projecting radially outward from the filler neck tube formed inside the wall to lock the filler neck tube to the fuel tank. The stop flange and the lock flange provide the sole means for securing the filler neck tube within the opening. The filler neck assembly further includes a seal interposed in the opening between the wall and the filler neck tube and a washer disposed inside the fuel tank between the wall and the lock flange to engage the seal.

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.

International Classification:

F02M033/02

US Classification:

123519000

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.

International Classification:

B65B 3100

US Classification:

141 59

Abstract:

A valveless fuel tank assembly for a vehicle including a fuel tank having an interior chamber to hold fuel therein. The valveless fuel tank assembly also includes a vapor canister to adsorb fuel vapor in the fuel tank. The valveless fuel tank assembly includes a fill-limit tube connected to the fuel tank and communicating with the interior chamber and a tank vent tube connected to the vapor canister and operatively connected to the fill-limit tube. The valveless fuel tank assembly further includes an oleophobic filter connected to the fill-limit tube to allow vapor fuel to communicate with the vapor canister and to prevent liquid fuel from communicating with the vapor canister.

International Classification:

F12K 1704

US Classification:

137 43

Abstract:

A fuel vapor control apparatus on a motor vehicle fuel tank including a vapor storage canister, a plurality of vent valves on the fuel tank, a plurality of vapor ducts between the vent valves and the vapor storage canister, a plurality of primary liquid traps, and a secondary liquid trap which cooperates with the primary liquid traps in preventing liquid fuel leaking through the vent valves from reaching and contaminating the vapor storage canister. The primary liquid traps are segments of respective ones of the vapor ducts defining standpipes above corresponding ones of the vent valves when the fuel tank is inclined. The primary liquid traps retain liquid fuel leaking through the vent valves and drain by gravity to the fuel tank when the incline of the fuel tank is reduced to zero. The secondary liquid trap is a secondary tank on the top of the fuel tank interposed between the vapor storage canister and the segments of the vapor ducts defining the standpipes. The secondary tank retains liquid fuel which overflows any one of the standpipes and also drains by gravity to the fuel tank when the incline of the fuel tank is reduced to zero.
