1
For ambient and altitude capabilities consult your Caterpillar dealer. Air flow restriction (system) is added to existing restriction from
factory.
2
Generator temperature rise is based on a 40º C (104º F) ambient per NEMA MG1-32.
3
Emissions data measurement procedures 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 operating conditions of 77ºF, 28.42 in HG and number 2 diesel fuel
with 35º API and LHV of 18,390 btu/lb. The nominal emissions data shown is subject to instrumentation, measurement, facility and engine
to engine variations. Emissions data is based on 100% load and thus cannot be used to compare to EPA regulations which use values
based on a weighted cycle.
