Curves shown above repressent gross engine performance capabilities obtained and corrected in accordance
℃
with SAE J1995 conditions fo 29.61 in.Hg(100 kPa) barometric pressure[300ft. (90 m) altitude], 77°F (25 ) inlet air
temperature, and 0.30 in.Hg (1 kPa) water vapor pressure with No. 2 diesel fuel or a fuel corresponding to ASTM
D2. The engine may be operated without changing the fuel setting up to 2600 m (7,546 ft.) altitude and 38°C
(100°F). For sustained operation at high altitudes, the fuel rate of the engine will be adjusted to limit performance
by 4% per 305 m (1,000 ft.) above 2600 m (7,546 ft.) altitude and 2% per 11°C above 38°C.
