NMOG, which is the mass emissions of non-methane hydrocarbons and oxygenated hydrocarbons, is calculated from the measurements of THC and [CH.
Then NMOG is calculated from the mass of NMHC as follows:
Another objective of the test was to demonstrate the destruction of CO and NMOG without reforming NOx.
It is important to note that NMHC is plotted here, since NMOG can only be represented as a mass.
The second stage system was effective in reducing CO and NMOG, without reforming NOx, with a temperature setpoint of 375 [degrees]F.
Test results of the full-size prototype second stage catalysts A & B showed improved NMOG removal efficiency from the benchmark.
higher temporary NMOG (non methane organic gas), CO and HCHO (formaldehyde) values apply to HLDTs and expire after 2008;

That's 10 mg/mile of NMOG and 20 mg/mile of NOx, for a total of 30 (which explains the new nomenclature, Tier 3, Bin 30).
