Fuel Tank: Description and Operation
Fig.4 Rear Mounted Fuel Cylinders:
Fig.5 Side Mounted Fuel Cylinders:
Four high-pressure fuel cylinders are used to store Compressed Natural Gas (CNG). Two of the 4 cylinders are mounted transversely behind the rear axle (Fig. 4). The other 2 cylinders are mounted longitudinally along the left side of the vehicle frame rail (Fig. 5).
Both the Maxi and Standard size vans will share the same fuel cylinder configuration.
The 4 cylinders store natural gas at pressures up to approximately 3600 psi.
Each fuel cylinder is equipped with its own manually operated fuel control valve. Each of these valves is equipped with a pressure relief safety device. For more information, refer to Fuel Cylinder Control Valves.
Fig.6 Fuel Cylinder Expiration Date Label:
A label affixed to the fuel filler door (Fig. 6), states the first fuel cylinder (container) expiration date. A similar label is attached to each individual fuel cylinder. The label on the fuel cylinder will state: the address of the fuel cylinder manufacturer; the cylinder expiration date; certain warnings; and cylinder certification numbers.
