MIL-DTL-62177E 6 3.3.6 Torque. The engine shall develop the torques specified in table I at the full power setting (see 4.6.2.1.3). TABLE I. Torque. Speed rpm Corrected torque lb-ft (N m) 1/ GCBHP 1800 1770 - 1842 (2400 - 2498) 607 - 631 2400 1609 - 1707 (2182 - 2315) 735 - 780 1/ lb-ft (N m) = pound foot (Newton meter) 3.3.7 Fuel consumption. The engine fuel consumption at the full power setting shall be as specified in table II (see 4.6.2.1.4). TABLE II. Fuel consumption. Speed rpm Maximum fuel consumption lb per hp-hour (kg per hp-hour) 1/ 1800 0.400 (181) 2400 0.420 (191) 1/ lb per horsepower hour = (kilogram (kg) per hp-hour) 3.3.8 Oil pressure. At an engine speed of 2400 to 2450 rpm with the engine oil temperature at 140 to 250°F (60 to 121°C) measured at the main oil gallery (oil cooler outlet), using grade 30 oil, the gallery oil pressure shall be not less than 40 pounds per square inch (psi), (275.8 kPa) nor more than 70 psi (482.7 kPa), measured at the pressure sending unit, and shall be not less than 15 psi (103.4 kPa) when the engine is idling (700 to 750 rpm) at all oil levels ranging from the “add” mark to the “full” mark on the dipstick (see 4.6.2.1.5). 3.3.9 Intake manifold pressure. The intake manifold pressure at the full power setting and at an engine speed of 2400 rpm shall be 2.05 to 2.35 times the turbocharger compressor housing inlet pressure (wet barometer reading). Variations between left and right banks shall not exceed 4 in. (13.5 kPa) Hg (see 4.6.2.1.6). 3.3.10 Exhaust smoke density. The exhaust smoke density (see 6.3) at the full power setting measured within the exhaust pipe not more than 3 feet (ft) [(0.91 meter (m)] from the turbocharger exhaust outlet flange shall be as specified in table III (see 4.6.2.1.7). TABLE III. Exhaust smoke density. Speed rpm Bosch smoke meter reading or equivalent (maximum) 1800 3.5 2000 3.2 2200 2.6 2400 2.4
