40-48 cetane number.

Fuel Temperature:

99 ± 9 °F (at fuel pump inlet)

Intake Air Temperature:

77 ± 9 °F

Barometric Pressure:

29.6 ± 1 in. Hg

Humidity:

NOx measurement corrected to 75 grains H

O/lb dry air

Reference Standard:

ISO 8178

The NOx, HC, CO and PM emission data tabulated here are representative of test data taken from a single engine under the test conditions

shown above. Data for the other components are estimated. 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 limits, or with improper maintenance, may results in elevated emission levels.
