1 CUMMINS ENGINE COMPANY, INC Columbus, Indiana ENGINE PERFORMANCE CURVE Basic Engine Model: Curve Number: -370E FR-1811 Engine Family: CPL Code: Date: D Aug93 55 Displacement: 855 in. 3 (14.0 litre) Aspiration: Turbocharged & Charge Air Cooled Bore: 5.5 in. (140 mm) BHP RPM Stroke: 6.0 in. (152 mm) No. of Cylinders: 6 Advertised BHP 370 (276) 1600 Emission Control ETC Fuel System: CELECT Governed Speed 1800 All data are based on the engine operating with fuel system, water pump, lubricating oil pump, air compressor (unloaded), and 8.5 in. H 2 O (216 mm H 2 O) inlet air restriction with 2.5 in. Hg (63 mm Hg) exhaust restriction; not included are alternator, fan, optional equipment and driven components. Maximum Full Load Governed Speed =1800 RPM Maximum No Load Governed Speed = 2000 RPM Brake Horsepower = 2000 RPM TORQUE RPM lb.-ft. N m POWER OUTPUT RPM BHP kw FUEL CONSUMPTION RPM lb/bhp-hr g/kw hr Curves shown above represent gross engine performance capabilities obtained and corrected in accordance with SAE J1995 conditions of in. Hg (100 kpa) barometric pressure [300 ft. (90 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 12,000 ft. (3 600 m) altitude and 100 F (38 C). For sustained operation at high altitudes, the fuel rate of the engine should be adjusted to limit performance by 4% per 1,000 ft. (300 m) above 12,000 ft. (3 600 m) altitude and 1% per 10 F above 100 F (2% per 11 C above 38 C). TECHNICAL DATA DEPT. CERTIFIED WITHIN 5% CHIEF ENGINEER
