| Post subject: | ISO Older Cummins Engine Torque and/or HP Curves |
I am in search of the engine torque and/or horsepower curves for the old Cummins 150 HP HBI-600 and HB-6I engines used in GE 23-50 tonners with GT-1503 main generators. I am also looking for the same for a Cummins NHC-250 engine which was sometimes used in later years to repower these locomotives. I have a photo of an NHC-250 engine plate in a 45-tonner that shows it was rated at 240 HP @ 2100 RPM. Both the HP and RPM seem too high for a GT-1503 generator, so I am thinking this engine was run at 1800 RPM tops and perhaps a lower power rating. I want to compare the torque and HP curves of as many of these engines as possible. Thanks! Tom Mack Cincinnati, OH |
