*
Ambient capability at 200 m (660 ft) above sea level. For ambient capability at other altitudes, consult your Caterpillar
dealer. Air flow restriction (system) is added to existing restriction from factory.
**
Generator temperature rise is based on a 40 degree C ambient per NEMA MG1-32.
***
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. This engine’s exhaust emissions are in compliance with the US EPA and California
nonroad regulations. Data shown is based on steady state operating conditions of 77 deg F, 28.42 in HG and number 2
diesel fuel with 35 deg API and LHV of 18,390 Btu/lb.
