<p>PURPOSE:To improve safety to a fuel leakage, by dividing a regulator decompressing compressed gas into at least more than two parts, while setting up a bomb and an upstream side regulator in a baggage housing area, and leading fuel gas after being decompressed into the engine side in a proper manner. CONSTITUTION:A regulator is divided into at least more than two parts, and among these divided regulators, an upstream side regulator 1 and a bomb 2 are set up in a baggage housing area 3 of a vehicle. Further, a downstream side regulator 4 and a mixer 5 are set in an engine housing area 6. And, an interval between these regulators 1 and 4 is connected with each other via a low pressure pipe line 8 to be laid on a car room area 7. With this constitution, fuel gas passing through the inside of the low pressure pipe line 8 is sharply decompressed by the upstream side regulator 1 so that probability of a leak in the point midway in the pipe line 8 can be brought to nothing. In addition, since length of the pipe line of high pressure fuel gas is reducible, safety is yet more improvable.</p> |
