20130312713 | Apparatus and Method of Determining a Leak Condition of a Fuel System - A portion of a fuel system of a vehicle is disclosed. The vehicle includes a motor-generator-starter connected to an engine. The fuel system includes a fuel tank connected to the engine. The portion of the fuel system includes an evaporative emissions system and an evaporative emissions leak check system connected to the evaporative emissions system. The evaporative emissions leak check system includes a vacuum source. The vacuum source includes the motor-generator-starter connected to the engine. The motor-generator-starter actuates the engine when the vehicle is operated in a non-moving, keyed-off condition for creating a vacuum within an intake manifold of the engine. A method is also disclosed. | 11-28-2013 |
20130312496 | System and Method of Implementing a Low Pressure Charcoal Canister - A portion of a fuel system of a vehicle is disclosed. The portion of the fuel system includes an evaporative emissions leak check system selectively fluidly-connected to an evaporative emissions system. The evaporative emissions leak check system includes a vacuum source. The evaporative emissions system includes a canister and a first fluid conduit fluidly-connecting the canister to the fuel tank. The portion of the fuel system also includes a vent valve that demarcates the first fluid conduit to include a first fluid conduit segment extending from the canister and a second fluid conduit segment extending from the fuel tank. The arrangement of the vent valve in an open orientation permits fluid communication of the canister with the fuel tank by way of the first fluid conduit. The arrangement of the vent valve in the closed orientation fluidly-isolates the canister from the fuel tank. A method is also disclosed. | 11-28-2013 |
