emissions certification test

the ofr/gpo partnership is committed to presenting accurate and reliable regulatory information on federalregister.gov with the objective of establishing the xml-based federal register as an acfr-sanctioned publication in the future. in the tier 3 final rulemaking, epa required vehicle manufacturers to perform greenhouse gas (ghg) and cafe fuel economy testing on the new tier 3 test fuel, beginning for model year 2020 and later vehicles. when we adopted the tier 3 test fuel, we indicated that we intended to undertake rulemaking to re-align test results from ghg and cafe fuel economy testing on the new tier 3 test fuel so they are consistent with test results from testing on the original tier 2 test fuel, in order to avoid an effective change in the stringency of the ghg and cafe standards. specifically, the proposed adjustments to vehicle testing results would avoid changes in the stringency of the ghg and cafe standards as a result of the test fuel transition. regarding the additional certification vehicle testing that the transition from tier 2 to tier 3 test fuel now underway will temporarily require, we discuss in section v below a proposed implementation schedule for the transition to required use of tier 3 test fuel (with the associated test procedure adjustments proposed here). as discussed in section iii, epa estimates that the impact on co2 emissions is a 1.6% difference, and thus without the test procedure adjustment proposed in this notice, a change from the tier 2 gasoline certification fuel to the tier 3 gasoline certification fuel would reduce the stringency of the epa co2 standards by 1.6%. our intent was to ensure that the stringency of the ghg and cafe programs would not be affected by the change in test fuel. [12] because of this, in 1986 epa adopted a modified carbon-balance fuel economy equation that was intended to align the calculated fuel economy values on average with 1975 test fuel and test conditions. our selection of vehicles for the test program was designed to address the narrow purpose of this rule: quantifying appropriate co2 and cafe adjustments that on average would prevent the change in the stringency of those standards that would otherwise occur as the certification test fuel changed. some stakeholders have asked epa to consider using the manufacturer-generated test data that they submit to the epa vehicle certification database as an alternative data source for estimating the impact of the change in co2 and fuel economy performance due to the test fuel change, rather than the data from the separate epa vehicle test program. epa requests comments on ways that manufacturer certification data submitted to epa, or any other data, might be used as an appropriate supplemental or alternative source of data for the purpose of quantifying the small average impacts on co2 and fuel economy due to the tier 3 test fuel change. the results indicate that for the federal test procedure (ftp) and the highway fuel economy test (hfet) cycles, going from tier 2 fuel to tier 3 fuel results in a reduction in co2 per mile of 1.78 and 1.02 percent, respectively, corresponding to absolute co2 emissions decreases of 6.37 and 2.16 g/mi, respectively. in contrast, this section describes how we used the test program results to determine adjustment factors that would maintain the stringency of the existing standards when testing is performed on tier 3 test fuel. in other words, the co2 emissions test results from a vehicle being tested for ghg compliance using tier 3 test fuel would be multiplied by this factor to arrive at the co2 value used for compliance. [29] because of the remaining offset seen in table iv-2, we are proposing an updated fuel economy equation for use with tier 3 test fuel where the r-factor is replaced by a new factor (ra), determined empirically so as to make the fleet-average fuel economy result using tier 3 test fuel numerically equivalent to the fleet-average result using tier 2 test fuel and r=0.6. because of the proposed changes to the measurement methods discussed in the previous paragraph and the new ra factor being specific to tier 3 test fuel, this proposed new equation would not be valid for reporting fuel economy when testing using tier 2 fuel.




for this reason, epa now believes that additional time is warranted before manufacturers are required to do all of their necessary ghg and fuel economy testing on tier 3 fuel and with the test procedure adjustments proposed in this notice. finally, beginning in my 2025, we propose that all testing for ghg and fuel economy reporting (including carryover testing) would need to be performed on tier 3 test fuel and use the proposed test procedure adjustment factors. regarding the additional certification vehicle testing that the transition from tier 2 to tier 3 test fuel now underway will temporarily require, we discuss in section v above a proposed implementation schedule for the transition to required use of tier 3 test fuel (with the associated test procedure adjustments proposed here). we propose that the city and highway fuel economy estimates for labels be determined from test results on tier 3 e10 test fuel, using the proposed new fuel economy equation, including the new ra adjustment factor, to align with tier 2 e0 test fuel results (as described in section iv.b above), beginning with testing for the same model year that cafe and ghg compliance for a vehicle becomes based on the new tier 3 e10 test fuel. for example, if a manufacturer switches one version of a vehicle model used in a sales weighted fuel economy label to the new tier 3 e10 test fuel and test procedures, the other versions used for that weighted label must also have results based on the tier 3 e10 test fuel. this proposed action is designed to ensure that the changes in vehicle test fuel characteristics occurring under existing regulations do not affect the stringency of the current ghg and fuel economy standards or unnecessarily add to manufacturer testing burdens. (4) measure emissions using the procedures of subpart b of this part and 40 cfr part 1066. determine separate emission results for the federal test procedure (ftp) described in 40 cfr 1066.801(c)(1) and the highway fuel economy test (hfet) described in 40 cfr 1066.801(c)(3). (1) testing to demonstrate compliance with corporate average fuel economy standards and greenhouse gas emission standards generally involves a combination of two cycles—the federal test procedure and the highway fuel economy test (see 40 cfr 1066.801). the following interim provisions apply: (1) manufacturers may optionally use this e10 gasoline test fuel starting in model year 2021 for vehicles subject to standards under 40 cfr 86.1818, and starting in model year 2022 for vehicles subject to standards under 40 cfr 86.1819. ra = sensitivity factor that represents the response of a typical vehicle’s fuel economy to changes in fuel properties, such as volumetric energy content. for fuel economy labels generated from e10 test data, use “a166 co2” input values to the equations in paragraph (d)(1) of this section (instead of cree input values), where “a166 co2” emissions are equal to the measured tailpipe co2 emissions for the test cycle multiplied by a factor of 1.0166 and rounded to the nearest 0.1 grams/mile. note that for fuel economy labels generated from e10 test data, the vehicle subconfiguration co2 values calculated in paragraph (a)(1) or (a)(2)(ii) of this section as applicable (which are used to calculate the configuration co2 values in this paragraph (a)(2)(iii)) are required to be “a166 co2” values, where “a166 co2” emissions are equal to the measured tailpipe co2 emissions for the test cycle multiplied by a factor of 1.0166 and rounded to the nearest 0.1 grams/mile. note that for fuel economy labels generated from e10 test data, the vehicle specific 5-cycle based co2 values calculated in § 600.114-12 are based on “a166 co2” values, where “a166 co2” emissions are equal to the measured tailpipe co2 emissions for the test cycle multiplied by a factor of 1.0166 and rounded to the nearest 0.1 grams/mile. note that for fuel economy labels generated from e10 test data, the mt hfet co2 input value is required to be “a166 co2” values for the model type, where “a166 co2” emissions are equal to the measured tailpipe co2 emissions for the test cycle multiplied by a factor of 1.0166, rounded to the nearest 0.1 grams per mile, as obtained in § 600.208-12(b)(3)(iii) and § 600.208-12(b)(4). 11.  note that because epa set the tier 3 “criteria emissions” standards based on testing on tier 3 e10 certification test fuel, there is no misalignment between those standards as the auto industry has transitioned to testing on tier 3 fuel for tier 3 certification, and thus no test procedure adjustments are needed for criteria emissions testing. for discussion of cree impacts in the epa test program, see memo “carbon-related exhaust emissions (cree) measured on current and proposed certification gasolines,” submitted by jim warila to docket epa-hq-oar-2016-0604. for example, if a manufacturer tests one version of a vehicle model used in a label on tier 3 e10 test fuel and tier 3 test procedures, the other test vehicle versions used for that label must also be tested using tier 3 e10 test fuel and test procedures.
