Specific Fuel Oil Consumption [ SFOC ] in Diesel/Marine Engines.

Why not follow the instructions in the operator's manual. There's an acronym for it. RTFM!

Or, just keep the temperature below 30°C.

Hello everybody:

The temperature of the engine charge air at the turbo compressor outlet can be calculated with the equation:

T₂ = (T₁ + T₁*(-1 + R_c^0,286)/E_c) - 273 [°C]

Where:

T₁ = ambient air temperature (compressor inlet) [°K]

T₂ = compressed air temperature (compressor outlet) [°K]

R_c = compression ratio

E_c = mechanical efficiency of compressor

It can be seen that conditioning (lowering) the inlet air temperature, the mass of air supplied by the compressor to the charge air coolers will be cooler as well.

The conditioning of the inlet air temperature can be accomplished by an evaporative cooler installed before the compressor inlet, where with the hotter and dried the air (low ambient humidity), the more water that can be absorbed by the evaporator, resulting in a cooler mass of air delivered by the compressor.

spray water through the radiator to remove the latent heat. one possibility would be to use one or more mist sprayers designed for a green house.
