***Ambient capability at 200 m (660 ft) above sea level. For ambient capability at other altitudes, consult your Caterpillar dealer.
***Assumes synchronous driver
***Emissions data measurement is consistent with those described in EPA CFR 40 PART 89 SUBPART D and ISO 8178-1 for
measuring HC, CO, CO2and NOx. Data shown is based on steady state engine operating conditions of 77° F, 28.43 inches HG
and fuel having a LHV of 920 BTU per cubic foot at 30.00 inches HG absolute and 32° F. Not to exceed emission data shown is
subject to instrumentation, measurement, facility and engine fuel system adjustments.
Standby — Output available with varying load for the
duration of the interruption of the normal source power.
Continuous — Output available without varying load
for an unlimited time.
Ratings are based on ISO3046/1 standard reference
conditions of 25° C (77° F) and 100 kPa (29.61 in Hg).
Ratings are based on pipeline natural gas having a LHV
(low heat value) of 36.2 mJ/N•m3(920 Btu/cu ft). Variations
in altitude, temperature, and gas composition from standard
conditions or the use of a three way catalyst may require
a reduction in engine horsepower.
