Hg (100 kpa) barometric pressure [300 ft. (91 m) altitude], 77 F (25 C) inlet air temperature, and 0.30 in. Hg (1 kpa) water vapor pressure with No.2 diesel fuel. The engine may be operated without changing the fuel setting up to 1000 ft. (300 m) altitude. For sustained operation at high altitudes, the fuel rate of the engine should be adjusted to limit performance by 3% per 1,000 ft. (305 m) above 1000 ft. (300 m) altitude and 1% per 10 F above 77 F (2% per 11 C above 25 C). TECHNICAL DATA DEPT. CERTIFIED WITHIN 5% CHIEF ENGINEER
