Test conditions
Data was recorded during steady-state rated engine speed (± 25 RPM) with full load (± 2%). Pressures, temperatures, and
emission rates were stabilized.
Fuel specification:
Natural gas:
Dry gas as received from Supplier (1000 BTU/SCF)
Propane:
Meets the requirements for Commercial Grade Propane under the ASTM D1835
Standard Specification for Liquefied Gases
Fuel temperature:
60 ± 9 °F at Flow Transmitter
Fuel pressure:
14.73 PSIA ± 0.5 PSIA at Flow Transmitter
Intake air temperature:
77 ± 9 °F at inlet
Barometric pressure:
29.92 in. Hg ± 1 in. Hg
Humidity:
NOx measurement corrected to 75 grains H2O/lb dry air
The NOx, HC, and CO emission data tabulated here were from a single engine under the test conditions shown above. These data are
subjected to instrumentation and engine-to-engine variability. Field emission test data are not guaranteed to these levels. Actual field test
results may vary due to test site conditions, installation, fuel specification, test procedures and instrumentation. Engine operation with
excessive air intake or exhaust restriction beyond published maximum limit, or with improper maintenance, may results in elevated emission
levels.
