Komatsu PC01 – HYDRAULIC EXCAVATOR – Performance curves

Tests were conducted according to SAE standard No. J607a. Power curves are for standard sea level atmospheric pressure of 29.92 in. (760 mm) Hg at a temperature of 60°F (15.6°C). Power curves are of a standard test engine equipped with standard air cleaner, muffler and other power consuming devices. Power output will decrease 3.5% for each, 1,000 ft. (305 m) of elevation above sea level and 1% for each 10 °F (5.6 °C) Frise above the standard temperature of 60 °F (15.6 °C). As shipped, production engines will develop not less than 90% of the “Maximum B.H.P.”
After being run-in, they will develop not less than 95% of the “Maximum B.H.P.” For practical operations, the B.H.P. load and engine speed should not exceed the limit defined by the “Recommended Maximum Operating B.H.P.” curve. Continuous operation should not exceed 85% of the Maximum B.H.P.
