AFTERCOOLER HEAT REJECTION FACTORS:

Aftercooler heat rejection is given for standard conditions of 77°F and 500 ft altitude. To maintain a constant inlet air manifold temperature, as

the ambient air 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. Failure to

properly account for these factors could result in detonation and cause the engine to shut down or fail.
