C-2.2.3 CERTIFICATES OF FUEL CONSUMPTION

Certification shall be submitted guaranteeing that engine fuel consumption does not exceed a maximum of 0.575 pounds per kilowatt hour for full and 3/4 load and 0.600 pounds per kilowatt hour for 1/2 load on the basis of:

(1) Net kW of the set corrected for engine auxiliaries that are electrically driven.

(2) 19,350 Btu per pound high-heat value for fuel used.
