All heat data is based on standard conditions according to attachment 0.10. Deviations from the standard conditions can result in a
change of values within the heat balance, and must be taken into consideration in the layout of the cooling circuit/equipment
(intercooler; emergency cooling; ...). In the specifications in addition to the general tolerance of ±8 % on the thermal output a further
reserve of 10 % is recommended for the dimensioning of the cooling requirements.

0.10 Technical parameters
All data in the technical specification are based on engine full load (unless stated otherwise) at specified
temperatures and the methane number and subject to technical development and modifications.
All pressure indications are to be measured and read with pressure gauges (psi.g.).
(1) At nominal speed and standard reference conditions ICFN according to DIN-ISO 3046 and DIN 6271,
respectively
(2) According to DIN-ISO 3046 and DIN 6271, respectively, with a tolerance of +5 %.
Efficiency performance is based on a new unit (immediately upon commissioning).Effects of
degradation during normal operation can be mitigated through regular service and maintenance work;
reference value --> 65%CH4
(3) Average value between oil change intervals according to maintenance schedule, without oil change
amount
(4) At p. f. = 1.0 according to VDE 0530 REM / IEC 34.1 with relative tolerances
(5) Total output with a tolerance of ±8 %
(6) According to above parameters (1) through (5)
(7) Only valid for engine and generator; module and peripheral equipment not considered (at p. f. = 0,8)
(8) Exhaust temperature with a tolerance of ±8 %
Radio interference level
The ignition system of the gas engines complies the radio interference levels of CISPR 12 and EN 55011
class B, (30-75 MHz, 75-400 MHz, 400-1000 MHz) and (30-230 MHz, 230-1000 MHz), respectively.
Definition of output
 ISO-ICFN continuous rated power:
Net break power that the engine manufacturer declares an engine is capable of delivering continuously,
at stated speed, between the normal maintenance intervals and overhauls as required by the
manufacturer. Power determined under the operating conditions of the manufacturer’s test bench and
adjusted to the standard reference conditions.
 Standard reference conditions:
Barometric pressure:
1000 mbar (14.5 psi) or 100 m (328 ft) above sea level
Air temperature:
25°C (77°F) or 298 K
Relative humidity:
30 %
 Volume values at standard conditions (fuel gas, combustion air, exhaust gas)
Pressure:
1013 mbar (14.7 psi)
Temperature:
0°C (32°F) or 273 K
Output adjustment for turbo charged engines
Standard rating of the engines is for an installation at an altitude ≤ 0 m and an air intake temperature ≤ 35
°C (T1). Maximum room temperature: 50°C (T2) -> engine stop

If the actual methane number is lower than the specified, the knock control responds. First the ignition
timing is changed at full rated power. Secondly the rated power is reduced. These functions are carried
out by the engine management system.
Exceedance of the voltage and frequency limits for generators according to IEC 60034-1 Zone A will lead
to a derate in output.
Parameters for the operation of GE Jenbacher gas engines
The genset fulfills the limits for mechanical vibrations according to ISO 8528-9.
The following "Technical Instruction of GE JENBACHER" forms an integral part of a contract and must be
strictly observed: TI 1100-0110, TI 1100-0111 and TI 1100-0112.
If possible, railway trucks must not be used for transport (TI 1000-0046).
Parameters for the operation of control unit and the electrical equipment
Relative humidity 50% by maximum temperature of 40°C.
Altitude up to 2000m above the sea level.
Parameters for using a gas compressor
The gas quantity indicated under the technical data refers to standard conditions with the given calorific
value. The actual volume flow (under operating conditions) has to be considered for dimensioning the gas
compressor and each gas feeding component – it will be affected by:
 Actual gas temperature (limiting temperature according to TI 1000-0300)
 Gas humidity (limiting value according to TI 1000-0300)
 Gas Pressure
 Calorific value variations (can be equated with methane (CH4) variations in the case of biogas)
 The gas compressor is designed for a max. relative under pressure of 15 mbar(g) (0.22 psi) and a inlet
temperature of 40°C (104°F) , if within scope of supply GE Jenbacher

All heat data is based on standard conditions according to attachment 0.10. Deviations from the standard conditions can result in a
change of values within the heat balance, and must be taken into consideration in the layout of the cooling circuit/equipment
(intercooler; emergency cooling; ...). In the specifications in addition to the general tolerance of ±8 % on the thermal output a further
reserve of +5 % is recommended for the dimensioning of the cooling requirements.

0.10 Technical parameters
All data in the technical specification are based on engine full load (unless stated otherwise) at specified
temperatures and the methane number and subject to technical development and modifications.
All pressure indications are to be measured and read with pressure gauges (psi.g.).
(1) At nominal speed and standard reference conditions ICFN according to DIN-ISO 3046 and DIN 6271,
respectively
(2) According to DIN-ISO 3046 and DIN 6271, respectively, with a tolerance of +5 %.
Efficiency performance is based on a new unit (immediately upon commissioning).Effects of
degradation during normal operation can be mitigated through regular service and maintenance work;
reference value --> 55%CH4
(3) Average value between oil change intervals according to maintenance schedule, without oil change
amount
(4) At p. f. = 1.0 according to VDE 0530 REM / IEC 34.1 with relative tolerances
(5) Total output with a tolerance of ±8 %
(6) According to above parameters (1) through (5)
(7) Only valid for engine and generator; module and peripheral equipment not considered (at p. f. = 0,8)
(8) Exhaust temperature with a tolerance of ±8 %
(9) Intercooler heat on:
* standard conditions (Vxx) - If the turbocharger design is done for air intake temperature > 30°C
w/o de-rating, the intercooler heat of the 1st stage need to be increased by 2%/°C starting from 25°C.
Deviations between 25 – 30°C will be covered with the standard tolerance.
* Hot Country application (Vxxx) - If the turbocharger design is done for air intake temperature >
40°C w/o de-rating, the intercooler heat of the 1st stage need to be increased by 2%/°C starting from
35°C. Deviations between 35 – 40°C will be covered with the standard tolerance.
Radio interference level
The ignition system of the gas engines complies the radio interference levels of CISPR 12 and EN 55011
class B, (30-75 MHz, 75-400 MHz, 400-1000 MHz) and (30-230 MHz, 230-1000 MHz), respectively.
Definition of output
 ISO-ICFN continuous rated power:
Net break power that the engine manufacturer declares an engine is capable of delivering continuously,
at stated speed, between the normal maintenance intervals and overhauls as required by the
manufacturer. Power determined under the operating conditions of the manufacturer’s test bench and
adjusted to the standard reference conditions.
 Standard reference conditions:
Barometric pressure:
1000 mbar (14.5 psi) or 100 m (328 ft) above sea level
Air temperature:
25°C (77°F) or 298 K
Relative humidity:
30 %
 Volume values at standard conditions (fuel gas, combustion air, exhaust gas)
Pressure:
1013 mbar (14.7 psi)
Temperature:
0°C (32°F) or 273 K
Output adjustment for turbo charged engines
14.12.2016/GE (8CA2)
Data Sheet J 320.docx

10/11
Standard rating of the engines is for an installation at an altitude ≤ 0 m and an air intake temperature ≤ 40
°C (T1)
Maximum room temperature: 50°C (T2) -> engine stop
If the actual methane number is lower than the specified, the knock control responds. First the ignition
timing is changed at full rated power. Secondly the rated power is reduced. These functions are carried
out by the engine management system.
Exceedance of the voltage and frequency limits for generators according to IEC 60034-1 Zone A will lead
to a derate in output.
Parameters for the operation of GE Jenbacher gas engines
The genset fulfils the limits for mechanical vibrations according to ISO 8528-9.
The following "Technical Instruction of GE JENBACHER" forms an integral part of a contract and must be
strictly observed: TA 1000-0004, TA 1100 0110, TA 1100-0111, and TA 1100-0112.
Transport by rail should be avoided. See TA 1000-0046 for further details
Failure to adhere to the requirements of the above mentioned TA documents can lead to engine damage
and may result in loss of warranty coverage.
Parameters for the operation of control unit and the electrical equipment
Relative humidity 50% by maximum temperature of 40°C.
Altitude up to 2000m above the sea level.
Parameters for using a gas compressor
The gas quantity indicated under the technical data refers to standard conditions with the given calorific
value. The actual volume flow (under operating conditions) has to be considered for dimensioning the gas
compressor and each gas feeding component – it will be affected by:
 Actual gas temperature (limiting temperature according to TI 1000-0300)
 Gas humidity (limiting value according to TI 1000-0300)
 Gas Pressure
 Calorific value variations (can be equated with methane (CH4) variations in the case of biogas)
 The gas compressor is designed for a max. relative under pressure of 15 mbar(g) (0.22 psi) and a inlet
temperature of 40°C (104°F) , if within scope of supply GE Jenbacher

All heat data is based on standard conditions according to attachment 0.10. Deviations from the standard conditions can result in a
change of values within the heat balance, and must be taken into consideration in the layout of the cooling circuit/equipment
(intercooler; emergency cooling; ...). In the specifications in addition to the general tolerance of ±8 % on the thermal output a further
reserve of +5 % is recommended for the dimensioning of the cooling requirements.

0.10 Technical parameters
All data in the technical specification are based on engine full load (unless stated otherwise) at specified
temperatures and the methane number and subject to technical development and modifications.
All pressure indications are to be measured and read with pressure gauges (psi.g.).
(1) At nominal speed and standard reference conditions ICFN according to DIN-ISO 3046 and DIN 6271,
respectively
(2) According to DIN-ISO 3046 and DIN 6271, respectively, with a tolerance of +5 %.
Efficiency performance is based on a new unit (immediately upon commissioning).Effects of
degradation during normal operation can be mitigated through regular service and maintenance work;
reference value --> 65%CH4
(3) Average value between oil change intervals according to maintenance schedule, without oil change
amount
(4) At p. f. = 1.0 according to VDE 0530 REM / IEC 34.1 with relative tolerances
(5) Total output with a tolerance of ±8 %
(6) According to above parameters (1) through (5)
(7) Only valid for engine and generator; module and peripheral equipment not considered (at p. f. = 0,8)
(8) Exhaust temperature with a tolerance of ±8 %
Radio interference level
The ignition system of the gas engines complies the radio interference levels of CISPR 12 and EN 55011
class B, (30-75 MHz, 75-400 MHz, 400-1000 MHz) and (30-230 MHz, 230-1000 MHz), respectively.
Definition of output
 ISO-ICFN continuous rated power:
Net break power that the engine manufacturer declares an engine is capable of delivering continuously,
at stated speed, between the normal maintenance intervals and overhauls as required by the
manufacturer. Power determined under the operating conditions of the manufacturer’s test bench and
adjusted to the standard reference conditions.
 Standard reference conditions:
Barometric pressure:
1000 mbar (14.5 psi) or 100 m (328 ft) above sea level
Air temperature:
25°C (77°F) or 298 K
Relative humidity:
30 %
 Volume values at standard conditions (fuel gas, combustion air, exhaust gas)
Pressure:
1013 mbar (14.7 psi)
Temperature:
0°C (32°F) or 273 K
Output adjustment for turbo charged engines
Standard rating of the engines is for an installation at an altitude ≤ 0 m and an air intake temperature ≤ 40
°C (T1)
Maximum room temperature: 50°C (T2) -> engine stop

If the actual methane number is lower than the specified, the knock control responds. First the ignition
timing is changed at full rated power. Secondly the rated power is reduced. These functions are carried
out by the engine management system.
Exceedance of the voltage and frequency limits for generators according to IEC 60034-1 Zone A will lead
to a derate in output.
Parameters for the operation of GE Jenbacher gas engines
The genset fulfills the limits for mechanical vibrations according to ISO 8528-9.
The following "Technical Instruction of GE JENBACHER" forms an integral part of a contract and must be
strictly observed: TI 1100-0110, TI 1100-0111 and TI 1100-0112.
If possible, railway trucks must not be used for transport (TI 1000-0046).
Parameters for the operation of control unit and the electrical equipment
Relative humidity 50% by maximum temperature of 40°C.
Altitude up to 2000m above the sea level.
Parameters for using a gas compressor
The gas quantity indicated under the technical data refers to standard conditions with the given calorific
value. The actual volume flow (under operating conditions) has to be considered for dimensioning the gas
compressor and each gas feeding component – it will be affected by:
 Actual gas temperature (limiting temperature according to TI 1000-0300)
 Gas humidity (limiting value according to TI 1000-0300)
 Gas Pressure
 Calorific value variations (can be equated with methane (CH4) variations in the case of biogas)
 The gas compressor is designed for a max. relative under pressure of 15 mbar(g) (0.22 psi) and a inlet
temperature of 40°C (104°F) , if within scope of supply GE Jenbacher

If the actual methane number is lower than the specified, the knock control responds. First the ignition
timing is changed at full rated power. Secondly the rated power is reduced. These functions are carried
out by the engine management system.
Exceedance of the voltage and frequency limits for generators according to IEC 60034-1 Zone A will lead
to a derate in output.
Parameters for the operation of GE Jenbacher gas engines
The genset fulfils the limits for mechanical vibrations according to ISO 8528-9.
The following "Technical Instruction of GE JENBACHER" forms an integral part of a contract and must be
strictly observed: TA 1000-0004, TA 1100 0110, TA 1100-0111, and TA 1100-0112.
Transport by rail should be avoided. See TA 1000-0046 for further details
Failure to adhere to the requirements of the above mentioned TA documents can lead to engine damage
and may result in loss of warranty coverage.
Parameters for the operation of control unit and the electrical equipment
Relative humidity 50% by maximum temperature of 40°C.
Altitude up to 2000m above the sea level.
Parameters for using a gas compressor
The gas quantity indicated under the technical data refers to standard conditions with the given calorific
value. The actual volume flow (under operating conditions) has to be considered for dimensioning the gas
compressor and each gas feeding component – it will be affected by:
 Actual gas temperature (limiting temperature according to TI 1000-0300)
 Gas humidity (limiting value according to TI 1000-0300)
 Gas Pressure
 Calorific value variations (can be equated with methane (CH4) variations in the case of biogas)
 The gas compressor is designed for a max. relative under pressure of 15 mbar(g) (0.22 psi) and a inlet
temperature of 40°C (104°F) , if within scope of supply GE Jenbacher

All heat data is based on standard conditions according to attachment 0.10. Deviations from the standard conditions can result in a
change of values within the heat balance, and must be taken into consideration in the layout of the cooling circuit/equipment
(intercooler; emergency cooling; ...). In the specifications in addition to the general tolerance of ±8 % on the thermal output a further
reserve of +5 % is recommended for the dimensioning of the cooling requirements.

All heat data is based on standard conditions according to attachment 0.10. Deviations from the standard conditions can result in a
change of values within the heat balance, and must be taken into consideration in the layout of the cooling circuit/equipment
(intercooler; emergency cooling; ...). In the specifications in addition to the general tolerance of ±8 % on the thermal output a further
reserve of +5 % is recommended for the dimensioning of the cooling requirements.

0.10 Technical parameters
All data in the technical specification are based on engine full load (unless stated otherwise) at specified
temperatures and the methane number and subject to technical development and modifications.
All pressure indications are to be measured and read with pressure gauges (psi.g.).
(1) At nominal speed and standard reference conditions ICFN according to DIN-ISO 3046 and DIN 6271,
respectively
(2) According to DIN-ISO 3046 and DIN 6271, respectively, with a tolerance of +5 %.
Efficiency performance is based on a new unit (immediately upon commissioning).Effects of
degradation during normal operation can be mitigated through regular service and maintenance work;
reference value --> 65%CH4
(3) Average value between oil change intervals according to maintenance schedule, without oil change
amount
(4) At p. f. = 1.0 according to VDE 0530 REM / IEC 34.1 with relative tolerances
(5) Total output with a tolerance of ±8 %
(6) According to above parameters (1) through (5)
(7) Only valid for engine and generator; module and peripheral equipment not considered (at p. f. = 0,8)
,(guiding value)
(8) Exhaust temperature with a tolerance of ±8 %
(9) Intercooler heat on:
* standard conditions (Vxx) - If the turbocharger design is done for air intake temperature > 30°C
w/o de-rating, the intercooler heat of the 1st stage need to be increased by 2%/°C starting from 25°C.
Deviations between 25 – 30°C will be covered with the standard tolerance.
* Hot Country application (Vxxx) - If the turbocharger design is done for air intake temperature >
40°C w/o de-rating, the intercooler heat of the 1st stage need to be increased by 2%/°C starting from
35°C. Deviations between 35 – 40°C will be covered with the standard tolerance.
Radio interference level
The ignition system of the gas engines complies the radio interference levels of CISPR 12 and EN 55011
class B, (30-75 MHz, 75-400 MHz, 400-1000 MHz) and (30-230 MHz, 230-1000 MHz), respectively.
Definition of output
 ISO-ICFN continuous rated power:
Net break power that the engine manufacturer declares an engine is capable of delivering continuously,
at stated speed, between the normal maintenance intervals and overhauls as required by the
manufacturer. Power determined under the operating conditions of the manufacturer’s test bench and
adjusted to the standard reference conditions.
 Standard reference conditions:
Barometric pressure:
1000 mbar (14.5 psi) or 100 m (328 ft) above sea level
Air temperature:
25°C (77°F) or 298 K
Relative humidity:
30 %
 Volume values at standard conditions (fuel gas, combustion air, exhaust gas)
Pressure:
1013 mbar (14.7 psi)
Temperature:
0°C (32°F) or 273 K
Output adjustment for turbo charged engines
Standard rating of the engines is for an installation at an altitude ≤ 0 m and an air intake temperature ≤ 35
°C (T1)
Maximum room temperature: 50°C (T2) -> engine stop
If the actual methane number is lower than the specified, the knock control responds. First the ignition
timing is changed at full rated power. Secondly the rated power is reduced. These functions are carried
out by the engine management system.
Exceedance of the voltage and frequency limits for generators according to IEC 60034-1 Zone A will lead
to a derate in output.
