*Heat rate (MJ/kWh) for gaseous fuel.

NOTES: • Ratings: Continuous power based on ISO 3046-1 standard reference conditions. • Power output: May require adjustment for values other than ISO 3046-1 standard reference conditions.

• Fuel as specified per ISO 8217. Limiting Caterpillar specification for fuel is VD8738 for crude oil operation at continuous power operation (COP). • Fuel consumption: Based on ISO 3046-1 standard reference conditions of 25° C (77° F) and 100 kPa (29.61 in Hg) , including one engine-driven lube oil pump, with 5% tolerance and LCV = 42 700 kJ/kg (18,358 Btu/lb) . • Dual Fuel (DF) engines: Specific fuel consumption (g/kWh) for liquid fuel; heat rate MJ/kWh for gaseous fuel. • Generator efficiency: Efficiency of 97.0% (96.0% for complete CM20 and CM25 model range, and for 6CM32, 8CM32, 9CM32) based on power factor 0.8 with medium voltage class generator; actual efficiency will depend on generator selection. • Crude oil operation only at continuous power generation.
