GAS ENGINE TECHNICAL DATA
NOTES
1
ENGINE RATING IS WITH 2 ENGINE DRIVEN WATER PUMPS. TOLERANCE IS ± 3% OF FULL LOAD.
2
GENERATOR POWER DETERMINED WITH AN ASSUMED GENERATOR EFFICIENCY OF 93% AND POWER FACTOR OF
0.8 [GENERATOR POWER = ENGINE POWER x GENERATOR EFFICIENCY].
3
ISO 3046/1 ENGINE EFFICIENCY TOLERANCE IS (+)0, (-)5% OF FULL LOAD % EFFICIENCY VALUE. NOMINAL ENGINE
EFFICIENCY TOLERANCE IS ± 3% OF FULL LOAD % EFFICIENCY VALUE.
4
THERMAL EFFICIENCY: JACKET HEAT + LUBE OIL HEAT + EXH. HEAT TO 350°F.
5
TOTAL EFFICIENCY = ENGINE EFF. + THERMAL EFF. TOLERANCE IS ± 10% OF FULL LOAD DATA.
6
ISO 3046/1 FUEL CONSUMPTION TOLERANCE IS (+)5, (-)0% OF FULL LOAD DATA. NOMINAL FUEL CONSUMPTION
TOLERANCE IS ± 3 % OF FULL LOAD DATA.
7
UNDRIED AIR. FLOW TOLERANCE IS ± 5 %
8
INLET MANIFOLD PRESSURE TOLERANCE IS ± 5 %
9
INLET MANIFOLD TEMPERATURE TOLERANCE IS ± 9°F.
10
TIMING INDICATED IS FOR USE WITH THE MINIMUM FUEL METHANE NUMBER SPECIFIED. CONSULT THE
APPROPRIATE FUEL USAGE GUIDE FOR TIMING AT OTHER METHANE NUMBERS.
11
EXHAUST STACK TEMPERATURE TOLERANCE IS (+)63°F, (-)54°F.
12
WET EXHAUST. FLOW TOLERANCE IS ± 6 %
13
NOX VALUES ARE SET POINTS AND WILL VARY WITH OPERATING CONDITIONS.
14
CO, CO2, THC, and NMHC VALUES ARE "NOT TO EXCEED".
15
O2% TOLERANCE IS ± 0.5; LAMBDA TOLERANCE IS ± 0.05. LAMBDA AND O2 LEVEL ARE THE RESULT OF ADJUSTING
THE ENGINE TO OPERATE AT THE SPECIFIED NOX LEVEL.
16
LHV INPUT TOLERANCE IS ± 3%.
17
HEAT REJECTION TO JACKET TOLERANCE IS ± 10 % OF FULL LOAD DATA, BASED ON TREATED WATER.
18
HEAT REJECTION TO ATMOSPHERE TOLERANCE IS ± 50% OF FULL LOAD DATA, BASED ON TREATED WATER.
19
HEAT REJECTION OF LUBE OIL TOLERANCE IS ± 20% OF FULL LOAD DATA, BASED ON TREATED WATER.
20
HEAT REJECTION TO EXHAUST TOLERANCE IS ± 10% OF FULL LOAD DATA, BASED ON TREATED WATER.
21
HEAT REJECTION TO A/C TOLERANCE IS ± 5 % OF FULL LOAD DATA, BASED ON TREATED WATER.
SITE SPECIFIC COOLING SYSTEM SIZING EQUATIONS (WITH TOLERANCES)
22
TOTAL JACKET CIRCUIT (JW+OC) = (JW x 1.1) + (OC x 1.2).
23
TOTAL AFTERCOOLER CIRCUIT (AC) = AC x ACHRF x 1.05.
