NOx** | VOC** | CO** |
80 ppmdv NOx | 240 ppmdv VOC | 176 ppmdv CO |
(1.5 g/bhp-hr)** | (1.5 g/bhp-hr) | (2.0 g/bhp-hr) |
* These requirements are in addition to requirements of section 2455 and 2456.
** For the purpose of compliance with this article, ppmdv is parts per million @ 15 percent oxygen averaged over 15 consecutive minutes. Limits of ppmdv are the approximate equivalent to the stated grams per brake horsepower hour limit based on assuming the engine is 24.2 percent efficient.
