PROBLEM TO BE SOLVED: To prevent the injection of a large quantity of the vaporized gas when returning the operation from the decelerating operation to the normal operation in the condition that the warming up is not concluded in a system for adjusting the liquefied gas to the vaporized gas at the predetermined positive pressure and injecting it so as to supply the vaporized gas to an engine. SOLUTION: When operating the deceleration in the non-warming up condition that the liquefied gas exists in a pressure adjusting chamber 14 of a pressure governor 10 and that the vaporization of this liquefied gas is progressed by the engine cooling water of a cooling water passage 28, the vaporized gas at a quantity within the flow range for making the combustible mixture is injected from a fuel injection valve 5 in response to the cooling water temperature, and combusted for consumption at an engine 7 so as to restrict the pressure rise of the pressure adjusting chamber 14 due to the vaporization of the liquefied gas, and operation can be smoothly returned to the normal operation without injecting a large quantity of the vaporized gas. |
