Abstract
PURPOSE:To enable holding of a switching valve in an opening state for a while, by a method wherein a negative pressure correcting circuit which maintains a negative pressure only for a given time when a manifold negative pressure is lowered is mounted to a negative pressure circuit adapted to actuate an actuator. CONSTITUTION:A vacuum diaphragm 12 controls opening and closing of a switching valve, forcing passage of air in an amount suitable for existing fuel in an opening state and passage of air in an amount suitable for liquefied gas fuel in a closed state, by utilizing a manifold negative pressure. A negative pressure correcting circuit, formed with a vacuum control valve 21 for regulating a negative pressure and a vacuum tank 22 for accumulating a negative pressure, is situated in a negative pressure circuit to actuate the diaphragm 12. When the negative pressure correcting circuit maintains a negative pressure only for a given time when a manifold negative pressure is decreased and therefore, a diaphragm to is not actuated during rapid acceleration running by existing fuel and the switching valve is held in an opening state for a while, whereby an engine can continue sound running state.
