Diesel Engine Rating Definitions
Explanation of Ratings A, B, C, D, and E:
For an exact determination of the appropriate rating, contact your
local Cat® dealer. Engine rating obtained and presented in
accordance with ISO3046/1.
A Rating (Continuous)
Continuous heavy-duty service where the engine is operated at
maximum power and speed up to 100% of the time without
interruption or load cycling.
B Rating
For service where power and/or speed are cyclic (time at full load
not to exceed 80%).
C Rating (Intermittent)
Intermittent service where maximum power and/or speed are cyclic
(time at full load not to exceed 50%).
D Rating
For service where maximum power is required for periodic overloads
(time at full load not to exceed 10% of the duty cycle).
E Rating
For service where maximum power is required for a short time for
initial starting or sudden overload. For emergency service where
standard power is unavailable (time at full load not to exceed 5% of
the duty cycle).

Rating Conditions
Diesel Engines — up to 6.6 liter
All rating conditions are based on ISO/TR14396, inlet air standard
conditions with a total barometric pressure of 100 kPa (29.5 in. Hg),
with a vapor pressure of 1 kPa (.295 in. Hg), and 25°C (77°F).
Performance measured using fuel to specification EPA 2D 89.330-96
with a density of 0.845-0.850 kg/L @ 15° C (59° F) and fuel inlet
temperature 40° C (104° F).
Diesel Engines — 7 liter and higher
All rating conditions are based on SAE J1995, inlet air standard
conditions of 99 kPa (29.31 in. Hg) dry barometer and 25°C (77°F)
temperature. Performance measured using a standard fuel with fuel
gravity of 35° API having a lower heating value of 42,780 kJ/kg
(18,390 btu/lb) when used at 29° C (84.2° F) with a density of 838.9 g/L.
Gas
Ratings are based on SAE J1349 standard conditions of 100 kPa
(29.61 in Hg) and 25° C (77° F). These ratings also apply at ISO3046,
DIN6271, and BS5514 standard conditions of 100 kPa (29.61 in Hg) and
27° C (81° F); and API 7B-11C standard conditions of 99 kPa
(29.28 in Hg) and 29° C (85° F) also apply.
Ratings are based on dry natural gas having an LHV of 35.54 MJ/Nm3
(905 btu/ft3). Variations in altitude, temperature, and gas composition
from standard conditions may require a reduction in engine
horsepower.
Turbocharged-Aftercooled ratings apply to 1525 m (5000 ft) and
25°C (77°F).
ISO 9001:2000 Certification
Factory-designed systems built at Caterpillar ISO 9001:2000 certified
facilities.
