ALLOWABLE INERTS IN THE FUEL:The maximum amount of free inerts in the fuel is limited to 5%.
FUEL SYSTEM LIMIT:Fuels with a Wobbe index lower than the limit, require a custom fuel system and engine control system mapping from the factory. The Wobbe index is determinedusing the Caterpillar Methane Number Calculation program.
FUEL USAGE GUIDE:This table shows the derate factor required for a given fuel. Note that deration occurs as the methane number decreases. Methane number is a scale to measuredetonation characteristics of various fuels. The methane number of a fuel is determined by using the Caterpillar Methane Number Calculation program.
TOTAL DERATION FACTORS:This table shows the deration required for various air inlet temperatures and altitudes. Use this information along with the fuel usage guide chart to help determineactual engine power for your site. The total deration factor includes deration due to altitude and ambient temperature, and air inlet manifold temperature deration.
ACTUAL ENGINE RATING:It is important to note that the Altitude/Temperature deration and the Fuel Usage Guide deration are not cumulative. They are not to be added togetherTo determine the actual power available, take the lowest rating between the Altitude/Temperature Deration and the Fuel Usage Guide Deration.
GENERATOR EFFICIENCY:Generator power determined with an assumed generator effeciency of 97% [generator power=engine power x 0.97]. If the actual generator efficiency is less than 97%[and greater than 95%], 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 = 97% - actual generator efficiency [%].
EXHAUST STACK TEMPERATURE:The exhaust stack temperature listed in the technical data is a nominal value with a tolerance = +35°C, -30°C (+63°F, -54°F)
AFTERCOOLER HEAT REJECTION FACTORS:Aftercooler heat rejection is given for standard conditions of 25°C and 152 m altitude. To maintain a constant air inlet manifold temperature, as the air to turbotemperature goes up, so must the heat rejection. As altitude increases, the turbocharger must work harder to overcome the lower atmospheric pressureThis 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 andaltitude conditions. Multiply this factor by the standard aftercooler heat rejection. Failure to properly account for these factors could result in detonation andcause the engine to shutdown or fail.
