THIS paper describes the background, technology, and recognizes the economies concerning a wider range of fuel quality for the railroad diesel locomotive.
Comparisons are made between normal railroad fuel and a wider range of fuel in eight one-year tests in three types of locomotive equipment.
The test fuels caused increases in engine deposits, wear, and in contamination of filters and lubricating oil. In five of the tests the test fuels did not interfere with locomotive availability. In three tests changes in materials or methods of maintenance were necessary for continuance of operations.
It appears that fuels of the types tested can be used without interfering with locomotive ability if proper precautions are taken.
