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.
