TOTAL DERATION FACTORS:

This table shows the deration required for various air inlet temperatures and altitudes. Use this information to help determine actual engine power

for your site. The total deration factor includes deration due to altitude and ambient temperature, and air inlet manifold temperature deration.

AFTERCOOLER HEAT REJECTION FACTORS:

Aftercooler heat rejection is given for standard conditions of 25°C and 150 m altitude. To maintain a constant air inlet manifold temperature, as the air to turbo

temperature goes up, so must the heat rejection. As altitude increases, the turbocharger must work harder to overcome the lower atmospheric pressure.

This increases the amount of heat that must be removed from the inlet air by the aftercooler. Use the aftercooler heat rejection factor to adjust for ambient and

altitude conditions. Multiply this factor by the standard aftercooler heat rejection.

GENERATOR EFFICIENCY:

Generator power determined with an assumed generator effeciency of 95% [generator power = engine power x 0.95]. If the actual generator efficiency is less than 95%

[and greater than 94.5%], the generator power [ekW] listed in the technical data can still be achieved. The BSFC values must be increased by a factor.

The factor is a percentage = 95% - actual generator efficiency.

SOUND DATA:

Data determined by methods similar to ISO Standard DIS-8528-10. Accuracy Grade 3.

CONTINUOUS POWER – 8,000 hrs./yr., for applicationswith load factors less than or equal to 100%. 10%overload available.

RATINGS are based on SAE J1995/ISO3046 standardconditions of 100 kPa (29.61 in. Hg), 25°C (77°F), and30% relative humidity at the stated charge air coolerwater temperature. Ratings also meet classificationsociety maximum temperature requirements of 45°C (113°F) air temperature to the turbocharger and32°C (90°F) seawater temperature without derate.

Additional ratings may be available for specific customerrequirements. Consult your Caterpillar representative foradditional information.

FUEL RATES are based on 35° API, 16°C (60°F) fuelused at 29°C (85°F) with a density of 838.9 g/liter (7.001 lbs/U.S. gal). Lower Heat Value (LHV) of 42 780 kJ/kg (18,390 Btu/lb). Tolerance is +5%. Includesall engine mounted pumps. BSFC without pumps is 3% less.

MARINE CERTIFICATION – Ratings are marineclassification society approved by ABS, BV, CCS, DnV,GL, LRS, and RINA. These societies have also grantedC280 factory line production approval which eliminatesrequirement for society surveyor witness test.

TOTAL DERATION FACTORS:

This table shows the deration required for various air inlet temperatures and altitudes. Use this information to help determine actual engine power

for your site. The total deration factor includes deration due to altitude and ambient temperature, and air inlet manifold temperature deration.

AFTERCOOLER HEAT REJECTION FACTORS:

Aftercooler heat rejection is given for standard conditions of 25°C and 150 m altitude. To maintain a constant air inlet manifold temperature, as the air to turbo

temperature goes up, so must the heat rejection. As altitude increases, the turbocharger must work harder to overcome the lower atmospheric pressure.

This increases the amount of heat that must be removed from the inlet air by the aftercooler. Use the aftercooler heat rejection factor to adjust for ambient and

altitude conditions. Multiply this factor by the standard aftercooler heat rejection.

GENERATOR EFFICIENCY:

Generator power determined with an assumed generator effeciency of 96% [generator power = engine power x 0.96]. If the actual generator efficiency is less than 96%

[and greater than 94.5%], the generator power [ekW] listed in the technical data can still be achieved. The BSFC values must be increased by a factor.

The factor is a percentage = 96% - actual generator efficiency.

SOUND DATA:

Data determined by methods similar to ISO Standard DIS-8528-10. Accuracy Grade 3.

TOTAL DERATION FACTORS:

This table shows the deration required for various air inlet temperatures and altitudes. Use this information to help determine actual engine power

for your site. The total deration factor includes deration due to altitude and ambient temperature, and air inlet manifold temperature deration.

AFTERCOOLER HEAT REJECTION FACTORS:

Aftercooler heat rejection is given for standard conditions of 25°C and 150 m altitude. To maintain a constant air inlet manifold temperature, as the air to turbo

temperature goes up, so must the heat rejection. As altitude increases, the turbocharger must work harder to overcome the lower atmospheric pressure.

This increases the amount of heat that must be removed from the inlet air by the aftercooler. Use the aftercooler heat rejection factor to adjust for ambient and

altitude conditions. Multiply this factor by the standard aftercooler heat rejection.

GENERATOR EFFICIENCY:

Generator power determined with an assumed generator effeciency of 96% [generator power = engine power x 0.96]. If the actual generator efficiency is less than 96%

[and greater than 94.5%], the generator power [ekW] listed in the technical data can still be achieved. The BSFC values must be increased by a factor.

The factor is a percentage = 96% - actual generator efficiency.

SOUND DATA:

Data determined by methods similar to ISO Standard DIS-8528-10. Accuracy Grade 3.

PRIME POWER – 6,000 hrs./yr., for applications with loadfactors less than or equal to 60%. Rated load (100%)usage is limited to 1 hour in 12. 10% overload available.

RATINGS are based on SAE J1995/ISO3046 standardconditions of 100 kPa (29.61 in. Hg), 25°C (77°F), and30% relative humidity at the stated charge air coolerwater temperature. Ratings also meet classificationsociety maximum temperature requirements of 45°C (113°F) air temperature to the turbocharger and32°C (90°F) seawater temperature without derate.

Additional ratings may be available for specific customerrequirements. Consult your Caterpillar representative foradditional information.

FUEL RATES are based on 35° API, 16°C (60°F) fuelused at 29°C (85°F) with a density of 838.9 g/liter (7.001 lbs/U.S. gal). Lower Heat Value (LHV) of 42 780 kJ/kg (18,390 Btu/lb). Tolerance is +5%. Includesall engine mounted pumps. BSFC without pumps is 3% less.

MARINE CERTIFICATION – Ratings are marineclassification society approved by ABS, BV, CCS, DnV,GL, LRS, and RINA. These societies have also grantedC280 factory line production approval which eliminatesrequirement for society surveyor witness test.
