Abstract
An engine-start is inhibited when a gas engine is tilted, and the engine is immediately stopped. A shutoff valve () is provided on a liquefied fuel passage () supplying a liquefied fuel to a vaporizing chamber () from a cylinder (). The shutoff valve () is provided with a diaphragm () to which a pulsation pressure of a crank chamber () is applied, and opens the liquefied fuel passage () if a negative pressure is applied to the diaphragm (). A tilting shutoff valve () is provided in a pressure passage () transmitting the pulsation pressure to the shutoff valve (). The tilting shutoff valve () which has a ball valve releases the pulsation pressure of the crank chamber () to an atmospheric air. If the pulsation pressure is open to the atmospheric air, the diaphragm () can not operate. Accordingly, the liquefied fuel passageis kept being shut off, and is rapidly shut off in response to the tilt during the operation.
