Abstract
A device including an internal combustion engine, an engine control device coupled to the internal combustion engine and manually operable to stop operation of the engine, a fuel tank coupled to the engine for providing fuel to the engine, and a fuel vent closure device communicating with the fuel tank. The fuel vent closure device is automatically and electrically operable in response to the manual operation of the engine control device to substantially seal the fuel tank when the engine is stopped, thereby substantially preventing emissions from the fuel tank. The device also preferably includes a fuel shutoff device automatically and electrically operable in response to the manual operation of the engine control device to substantially block the supply of fuel to the engine when the engine is stopped.
