THIS WORK PACKAGE COVERS:
The engine must operate satisfactorily under all loads through a speed range of 1000 to 2400 rpm and must idle
satisfactorily at 825--875 rpm.
Gross Horsepower (Without Accessories)
Under full throttle setting, engine will develop 1050--1080 gross horsepower at 2400 rpm, using fuel conforming to
Specification JP--8 MIL--T--83133.
Gross Torque (Without Accessories)
Under full throttle setting, engine will develop the following gross torque using fuel conforming to Specification JP--8
2422 to 2509 lb--ft (3284 to 3402 NSm) at 1800 rpm.
2298 to 2363 lb--ft (3116 to 3204 NSm) at 2400 rpm.
Oil consumption is checked only on 50--hour tests.
Engine shall not consume more than 0.0075 pounds (0.01017 NSm) per brake horsepower hours (lbs/bhp/hr) of
lubricating oil when operating under full load and using engine oil conforming to Military Specification MIL--L--2104,
Fuel Consumption (Without Accessories)
When operating at full throttle under full load, on a dynamometer, at a speed of 2400 rpm, engine shall consume
not more than 0.420 pounds (0.56952 NSm) per brake horsepower hour (lbs/bhp/hr) fuel conforming to Specification
JP--8 MIL--T--83133. When operating at full throttle under full load, on a dynamometer at 1800 rpm, the engine
shall not consume more than 0.400 lbs/bhp/hr (0.5424 NSm) of fuel conforming to JP--8 MIL--T--83133.
Exhaust Gas Temperature
The engine shall not exceed the following maximum allowable temperatures when operating at full power setting,
with an air inlet maximum temperature of 120°F (48.9°C), from maximum torque rpm to rated rpm. Air inlet temper-
ature shall be measured at the turbocharger compressor inlet.
(1) Exhaust gas temperature: 1400°F (760°C) measured at individual cylinder ports with turbocharger inlet air flow
restriction less than 1.0 inch of Hg.
(2) Exhaust temperature variation between cylinders shall not exceed 250°F (121°C) under full load conditions,
350°F (176.7°C) below 2100 rpm.
With engine under full throttle and full load, blow--by shall not exceed 23.5 cfm with new cylinders, and 27 cfm with
Lubricating Oil Temperature
Temperature of oil in the engine gallery shall not exceed 250°F (121°C). Temperature of oil entering the engine
through the oil pump shall be maintained between 140°F and 250°F (60°C and 121°C).
