§ 1045.107 - What are the not-to-exceed emission standards?
Not-to-exceed emission standards apply as follows:
(a) Measure emissions using the not-to-exceed procedures in subpart F of this part:
(b) Determine the not-to-exceed standard, rounded to the same number of decimal places as the emission standard in Table 1 to this section from the following equation:
Not-to-exceed standard = (STD) × (M) Where: STD = The standard specified in paragraph (a) of this section if you certify without using ABT for that pollutant; or the FEL for that pollutant if you certify using ABT. M = The NTE multiplier for that pollutant, as defined in paragraphs (c) through (e) of this section.(c) For engines equipped with a catalyst, use NTE multipliers from the following table across the applicable zone specified in § 1045.515:
Table 1 to § 1045.107—NTE Multipliers for Catalyst-Equipped Engines
Pollutant | Subzone 1 | Subzone 2 | HC + NO | 1.50 | 1.00 | CO | N/A | 1.00 |
---|
(d) For two-stroke engines not equipped with a catalyst, use an NTE multiplier of 1.2 for HC + NO
(e) For engines not covered by paragraphs (c) and (d) of this section, use the NTE multipliers from the following table across the applicable zone specified in § 1045.515:
Table 2 to § 1045.107—NTE Multipliers for Four-Stroke Engines without Catalysts
Pollutant | Subzone 1 | Subzone 2 | HC + NO | 1.40 | 1.60 | CO | 1.50 | 1.50 |
