Rail-Buckeye Automatic Fuelling System for Diesel Locomotives

The Buckeye Automatic Fuelling System uses only two basic components: The adapter and the nozzle.

Adapter assembly:

• The Emco Wheaton adapter is mounted to the diesel unit at each fuelling connection on the locomotive chassis
• Minimal modification is required for installation. Simply remove existing fuel fittings and replace with the adapter
• All adapters are equipped with dust caps
• A manual adapter is available when refuelling cannot be done with the nozzle

Automatic nozzle:

• One basic nozzle handles all fuelling requirements and provides a fuel flow range from 50 to 300 GPM
• The nozzle is hydraulically balanced to permit easy opening and shock-free closing
• This feature makes it possible to save fuelling time by starting the pump before attaching the nozzle
• Increased pumping rates are also possible since higher pump relief valve settings may be used with safety
• The nozzle assures automatic shut-off when the fuel tank reaches capacity.
• When fuel level reaches the level shut-off tube, fuel transfer is shut off automatically and the tank is full
• Overfill and underfill conditions are completely avoided. Fuel tank levels are consistent from fill to fill
• Spill hazard is virtually eliminated
• Since automatic shut-off is housed in the nozzle and not in the locomotive, bench repairs can be made without involving locomotive downtime
• This feature keeps the locomotives in service as maintenance takes place
• The tripping mechanism of the nozzle seals it against dirt, dust and other foreign matter
• Additional reliability and long service life come from a Teflon piston seal and Teflon bearings
• Safety features include a test plug for checking pressure and flow rate
• Fuelling operations are eased by a raised ramp on the outlet coupler ring that provides easy nozzle attachment and release from the locomotive
