C280-16 Engine Caterpillar

Rating Conditions

The engine ratings are based in compliance with the following standard ambient air conditions of "SAE J1995 January 1990" and "ISO3046":

• Dry barometric pressure of 99 kPa (14.4 psi)

• Temperature of 25° C (77° F)

Engine performance and fuel consumption are based on the following fuel specifications:

• The low heat value (LHV) of the fuel is 42780 Kj/kg at 29 °C.

• The density of the fuel is 838.9 g/L.

The following tolerances are included:

• ± 5 percent for specific fuel consumption

• ± 3 percent for brake kilowatts at the flywheel

The power at the flywheel is demonstrated at a Caterpillar Engine test cell.

Before engine power is derated, the maximum temperature of the inlet air to the turbocharger is 45° C (113° F).

The engine ratings represent net power. The power that is required for the following parameters has been subtracted from the net power:

• Air filter restriction

• Exhaust restriction

• Fuel pump

• Pumps that circulate lube oil

• Water pumps
