DEFINITIONS AND CONDITIONS
(1) Continuous --- Maximum output available for an unlimited time
Ratings are based on pipeline natural gas having a Low Heat Value (LHV) of 36 MJ/NM3 (915
Btu/ ft3) and 80 Caterpillar Methane Number. For values in excess of altitude, ambient
temperature, inlet/ exhaust restriction or different from the conditions listed, contact your local
Caterpillar dealer.
(2) Efficiency of standard generator is used. For higher efficiency generators, contact your local
Caterpillar dealer.
(3) Ratings and fuel consumption are based on ISO3046/1 standard reference conditions of 25
deg C (77 deg F) of ambient temperature and 100 kPa (29.61 in Hg) of total barometric
pressure, 30% relative humidity with 0, +5% fuel tolerance.
(4) Altitude capability is based on 2.5 kPa air filter and 5.0 kPa exhaust stack restrictions.
(5) Heat Rejection -- Values based on nominal data with fuel tolerance of +/-2.5% and
kPa inlet and 5.0 kPa exhaust restrictions.
2.5
(6) Assume synchronous driver.
(7) Emissions data measurements are consistent with those described in EPA CFR 40 Part 89
Subpart D & E and ISO8178-1 for measuring HC, CO, PM, NOx. Data shown is based on
steady state engine operating conditions of 25 deg C (77 deg F), 96.28 kPa (28.43 in Hg) and
fuel having a LHV of 35.6 MJ/NM3 (905 Btu/cu ft) and 80 Caterpillar Methane Number at
101.60 kPa (30.00 in Hg) absolute and 0 deg C (32 deg F). Emission data shown is subject to
instrumentation, measurement, facility, and engine
