<p>PURPOSE:To avoid the overlap of pipelines even when a filling port and an engine are at the front part of a one-box type body and gas cylinders are at the rear part. CONSTITUTION:A fuel filling line 34 branches off from a branch point 39 at the intermediate part of a fuel feed line 24 for leading gas fuel to an engine 21 from gas cylinders 22, 23. When gas fuel filling operation is performed, the opening operation of a filling door 38, for instance, is detected by a microswitch 41, and an emergency shutoff valve 25 is opened by a control device 40. Gas fuel can be thereby filled into the gas cylinders 22, 23 from the fuel filling line 34. Since a fuel shutoff valve 26 is kept in the closed state, the filled gas fuel is prevented from being fed to the engine 21 side.</p> |
