Subject: Requested Information from DuPont Fayetteville Works
Greg:
Here is most of the outstanding information on the electrical generator in the Nafion® area,
which I found by peaking through the generator frame's vent slits to see the engine mounted
inside of it.
- Engine Manufacturer: John Deere
- Engine: PowerTech 8.1 L
- Engine Fuel: Diesel
- Engine Size (horsepower): 310 - 426 HP ( * see note )
- Date of Engine: 2000 - 2001 ( ** see note )
- Engine Model Number: RG6081TIO579
* Note: According to the John Deere website, the PowerTech 8.1 L diesel engine that is used
with electrical generators is available as either 310 HP, 349 HP, 388 HP or 426 HP. There is
no information that I could see on the engine to indicate which HP applies to this engine.
So I guess you can assume the worst -case of 426 HP.
** Note: We found a P&I drawing dated 08-02-2000 for the electrical portion of project that
installed this generator. It is believed that the generator was actually installed in 2001,
although one could assume that the engine manufactured by John Deere that was sold to Kohler
and installed in this generator could easily have been assembled in 2000. So I would list
the date of the engine as 2000.
