<35 mg/MJ Sulfur compounds are those that
contain sulfur. The total sulfur
level must account for all sulfur
in the fuel and can be expressed
as the equivalent of H

S
Total halide compounds ex-
pressed as CL CL + FL + I + Br <19 mg/MJ Halide compounds are those that
contain chlorine, fluorine, iodine,
or bromine. Total halide levels
must take into account all halides
and be expressed as the equiva-
lent chlorine.

<1.19 mg/MJ No condensation in gas train and
inlet manifold allowed
Silicon Si <0.56 mg/MJ Lubricating oil analysis to show a
metal content of <15 mg/kg of oil
Maximum humidity (relative) - <80 percent At lowest inlet temperature, no
condensation in inlet manifold
and gas train allowed
Min/max. gas pressure 4006TRS
and 4008TRS engines
-
15 to 50 mbar At inlet to air fuel ratio regulator
Min/max. gas pressure 4006TRS
and 4008TRS engines with Elek-
tra and 4016TRS - 50 to 250 mbar At inlet to air fuel ratio regulator
Maximum fluctuation in gas
pressure
-
3 mbar Maximum rate of change of gas
pressure is 3 mbar/min, variation
frequency < 5/h
Min/max. gas temperature
-
10° to 50°C (50° to 122°F)
-
Sour gases are the following:
• Landfill gas
• Digester gas
• Bio gas
• Mine gas
The gas specification requirements are to be used as
a guide only. Perkins require a full gas analysis to be
supplied at the inquiry stage of an engine order.
Engine rating depends on the low calorific value of
the fuel and may be adapted to suit the specifics of
the fuel.
Total possible derate is calculated by adding
individual derate for:
• Charge cooler water inlet temperature
• Altitude
• Ambient temperature
• Lower calorific value
• Methane number
• Volumetric considerations
