ABSTRACT:
A device includes 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 operable in response pressure changes in the engine 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 operable in response to pressure changes in the engine to substantially block the supply of fuel to the engine when the engine is stopped.
