Abstract
A fuel system, a method for operating the fuel system and a method for operating an engine which is supplied by the fuel system each comprise: (1) a fuel tank; (2) a fuel vapor tank in fluid communication with the fuel tank by means of a first fuel vapor conduit; and (3) an engine in fluid communication with the fuel vapor tank by means of a second fuel vapor conduit. Within each of the fuel system and the two methods, there is captured, contained and compressed within the fuel vapor tank a fuel vapor extracted from the fuel tank when either: (1) refueling the fuel tank whether or not the engine is operating; (2) when the engine is operating whether or not refueling the fuel tank; or (2) immediately after shutting down the engine after having operated the engine. The fuel vapor within the fuel vapor tank may then be employed alone for restarting the engine, in absence of liquid fuel from the fuel tank.
