†
ENGINE RATINGS BASELINES
Engines are rated at standard SAE conditions of 29.61 in. (7521 mm) Hg barometer and 77˚F (25˚C) inlet air temperature [approximates 300 ft. (91.4
m) above sea level] by the testing laboratory (see SAE Standard J 1349).
A deduction of 3 percent from engine horsepower rating at standard SAE conditions shall be made for diesel engines for each 1000 ft. (305 m) altitude
above 300 ft. (91.4 m).
A deduction of 1 percent from engine horsepower rating as corrected to standard SAE conditions shall be made for diesel engines for every 10˚F
(5.6˚C) above 77˚F (25˚C) ambient temperature.
GUARANTEED POWER AT ANY SPEED
Although Guaranteed BHP ratings are shown at specific speeds, Clarke engines can be applied at any
intermediate speed, but must be factory set for final desired speed. To determine the intermediate certified power, make a linear interpolation from the Clarke Guaranteed power curve. Contact Clarke or your
Pump OEM representative to obtain details.
