What is Ambient Based Rating?
• Ambient based rating (ABR) is a feature built into the G3600 A4
system that allows for increased power output based on the ambient
temperature.
• Gas compression packages with the G3600 A4 that utilize ABR can
move more gas whenever ambient temperatures are below summer
highs.
Lower Temperature = Higher Power
Ambient Based Rating Concept
Engine power capability is in part limited by the temperature of the
combustion air as it enters the cylinder – Inlet Manifold Air Temperature
(IMAT)
• IMAT is affected by: • SCAC water temp is affected by:
– Engine load – SCAC system cooler capacity
– Ambient air temperature – Ambient air temperature
– Separate Circuit Aftercooler Cooler -
(SCAC) water temp
G3616 AIR SYSTEM ILLUSTRATION
Ambient Based Rating Concept
• Above a given ambient air temperature the cooler “approach
temperature” design limit is reached
– Engine thermostat will be fully open
– Cooler capacity is fully utilized
– SCAC water temp and IMAT AMBIENT TEMP VS SCAC TEMP

will increase with air temperature

• Below the approach temperature
SCAC water temperature is held
relatively constant by the engine
thermostat and cooling system
Ambient Based Rating Concept
• During cooler weather SCAC water temp can be held lower than the
typical 540C (1300F). This provides a lower IMAT temperature.
• With lower IMAT temperature additional engine power is available.
ENGINE POWER CAPABILITY
Ambient Based Rating Advantage
• During periods of lower ambient temperature, higher engine power is
available when ABR is effectively applied.
• There is increased engine power available for more compressor
throughput on a daily or seasonal basis.

POWER CAPABILITY WITH TEMPERATURE VARIATION

Ambient Based Rating Advantage Example:
• Pittsburgh, PA temperature data indicates that using the G3600 A4
32°C (90°F) SCAC and ABR allows:
– Average of 6.6% more power than G3600 A4 54°C (130°F) rating
– Average of 12.6% more power than G3600 A3 54°C (130°F ) rating
– 11°C (20°F) approach temperature assumed
Ambient Based Rating Advantage Example:
Power Capability – Pittsburgh, PA

Temperature data: http://www.ncdc.noaa.gov/cdo-web/ 3 years - 2011-2013 analysis

Ambient Based Rating Advantage Example:
• San Antonio, TX temperature data indicates that using the G3600
A4 32°C (90°F) SCAC and ABR allows:
– Average of 5.6% more power than G3600 A4 54°C (130°F) rating
– Average of 11.5% more power than G3600 A3 54°C (130°F) rating
– 11°C (20°F) approach temperature assumed
Ambient Based Rating Advantage Example:
Power Capability – San Antonio, TX

Temperature data: http://www.ncdc.noaa.gov/cdo-web/ 3 years - 2011-2013 analysis

Enabling Ambient Based Rating Feature
• The ABR feature is included when a 43°C (110°F) or 32°C (90°F)
rating is purchased.
• A flash file upgrade can be purchased from your Cat dealer for a
G3600 A4 engine in the field using the feature protection system.
• The highest rating purchased can be enabled in Cat ET.
• The following ratings are available:
Power Output bkW (bhp) @ 1000 rpm
Engine Standard 54°C (130°F) Rating 43°C (110°F) Rating 32°C(90°F) Rating
G3606 1875 (1398) 1950 (1454) 2010 (1499)
G3608 2500 (1864) 2590 (1931) 2675 (1995)
G3612 3750 (2796) 3875 (2889) 4000 (2982)
G3616 5000 (3729) 5175 (3859) 5350 (3990)
Engine Operation – With Ambient Based Rating
• As SCAC water temperature and IMAT varies the engine will
continue to adjust itself to maintain emissions, speed and power.
• The correct engine SCAC thermostats must be installed to match
the full power rating being utilized.
• To be effective, actual engine load (torque) must be varied to keep
the engine at or below its available load (torque) under the current
operating conditions.

SCAC Temp Thermostat Part Number Quantity (Vee) Quantity (Inline)

32°C (90°F) Rating 6I-4953 12 6
43°C (110°F) Rating 283-7776 12 6
54°C (130°F) Rating 204-6708 12 6
Ambient Based Rating Load Signals
• 4-20mA signals are used to communicate the engine’s actual load
(% of Full Load) and % of Available Load to the customer’s
compressor load controller.
• The compressor load controller must use this information to keep
the system load at or below the engines current capability.
• Load signals are also available via the engines Modbus interface.

Ambient Based Rating Signal Details
• % of Full Rating (Torque)
– Scaled 0% to 110% of installed rating
– 0% = 4ma, 100% = 18.55ma, 110% = 20ma
– Signal at EIC pin 28(+) and EIC pin 29(-)
– J1939 data link SPN:92, Modbus address: OCP 40851, Product Link 40138
• % of Available Load (Torque)
– Scaled 0% to 110% - actual scale will vary with temperature.
• Value is the (% of full rating / rating potential w/current temperatures)
– 0% = 4ma, 100% = 18.55ma, 110% = 20ma
– Signal at EIC pin 30(+) and EIC pin 31(-)
– J1939 data link SPN:513, Modbus address: OCP 40427, Product Link 44658
Details on Ambient Rating Signals
• % of Full Rating (Torque)
– Provides an indication of the actual torque the engine is delivering, compared to
the full rating of the engine at its rated SCAC water temperature.
– The % of full rating should never be allowed to exceed 100% for an extended
period of time. Operating above 100% increases the likelihood of a detonation
or temperature related shutdown.
– At 110% of full rating the engine will shutdown for engine overload.
– The signal is torque based, for most reciprocating compressor applications
varying engine speed will not significantly impact the torque required by the
compressor load.
Details on Ambient Rating Signals
• % of Available Load (Torque)
– Provides an indication of the actual torque the engine is delivering, compared to
the capability of the engine at the actual SCAC and IMAT temperatures.
– The actual torque scale represented by this signal will vary with temperature.
– The % of torque available should never be allowed to exceed 100%. Operating
above 100% increases the likelihood of a detonation or temperature related
shutdown.
– The signal is torque based, for most reciprocating compressor applications
varying engine speed will not significantly impact the torque required by the
compressor load.
Details on Ambient Rating Signals – Signal Summary
– % of Full Rating – ECM output scaled 0-110% of installed rating
– Installed rating is a constant dependent on engine configuration
– RPM – engine speed in RPM, can be constant for calculation on fixed speed
applications, or read from engine ECM at registers (J1939 and Modbus) OCP
40203, Product Link 40100
– Actual Engine Power – calculation (see below)
– % of Available Load – ECM output scaled 0-110% - actual engine load
compared to ambient based potential of engine under current temperature
conditions.
– Engine Power Torque Capability (under current conditions) – calculation (see
below)
– Engine Power Capability (under current conditions) – calculation (see below)
Details on Ambient Rating Signals
• Relationship Between Signals
– % of Full Rating: ECM output scaled 0-110% of Installed Rating
• Actual engine torque as a percentage of the installed rating.
• Installed rating is a constant and dependent on the actual engine configuration. The
scale can be equivalent to any of the three available SCAC ratings for the engine.

– Actual engine power being delivered is dependent upon engine speed and
torque, and can be calculated by the user as follows:
Actual Engine Power (HP) =
% of Full Rating * Installed Rating (HP) * Actual RPM/1000
Details on Ambient Rating Signals
• Relationship Between Signals
– % of Available Load: ECM output scaled 0-110%. Actual engine load percent
compared to ambient based potential of the engine under current temperature
conditions.
– Engine Power Capability (under current conditions) can be calculated by the
user as follows:
• Engine Torque Capability (%) = % of Full Rating / % of Available Load
• Engine Power Capability (HP) = Actual Engine Power (HP) / % of Available Load
Sizing & Other Considerations - Compressor

• Compressor sizing should be • Care must be taken to ensure

must be included to take • To be effective, actual engine
advantage of the capability. load (torque) must be varied to
keep the engine at or below its
available load (torque) under
the current operating
conditions.
Ambient Temperatures Limit Site Ratings
• Air-cooled radiators are common on gas compression installations
• Site ratings depend on the coolant temperature from the cooler
– Site ambient air temperature affects the coolant temperature returned to t
engine which in turn regulates the combustion air
temperature, a key determinant for detonation
– Oversized coolers can help,
but add cost and have
practical limits for approach temp
Ratings Available for High Ambient Temps
• G3600 high ambient ratings – via GERP
(shown for 55°C (131°F) ambient)
– G3606 A4 1800 bhp @ 1000 rpm, 65°C (149°F) SCAC
– G3608 A4 2412 bhp @ 1000 rpm, 65°C (149°F) SCAC
– G3612 A4 3625 bhp @ 1000 rpm, 65°C (149°F) SCAC
– G3616 A4 up to 65°C (149°F) SCAC, requires SRR
• GERP will provide rating up to 60°C (140°F) SCAC
Sizing & Other Considerations
• Cooler
– The engine cooler should be sized for the highest power rating for both jacket
water and aftercooler circuits
• Torsional Vibration Analysis (TVA)
– A thorough TVA must be done on the package to ensure that all speed and load
points are free of significant torsional vibration
• Emissions
– In applications where ambient based rating will be used it is likely emissions
permitting will be based on the highest power rating to be utilized
– Consult with the local permitting authority for specific requirements
