![]() For all other heavy-duty diesel engines the aforementioned period shall be 5 years/100,000 miles, whichever occurs first. ![]() Warranty period, for purposes of HDE emissions defect warranty and emissions performance warranty, shall be a period of 5 years/50,000 miles, whichever occurs first, for Otto-cycle HDEs and light heavy-duty diesel engines. In lieu of testing an emission-data or durability vehicle (or engine) selected under § 86.096–24(b)(1) introductory text, (b)(1)(iii)–(b)(1)(vi) and § 86.000–24(b)(1)(i)–(b)(1)(ii) and § 86.098–24(b)(1)(vii)(A)–(b)(1)(viii)(A) or § 86.096–24(c), and submitting data therefor, a manufacturer may, with the prior written approval of the Administrator, submit exhaust emission data, evaporative emission data and/or refueling emission data, as applicable, on a similar vehicle (or engine) for which certification has been obtained or for which all applicable data required under § 86.001–23 has previously been submitted. (f ) Carryover and carryacross of durability and emission data. Where a paragraph in § 86.096–24, § 86.098–24 or § 86.000–9 is identical and applicable to § 86.001–24, this may be indicated by specifying the corresponding paragraph and the statement “. If more than one vehicle meets this criterion, then within that vehicle grouping, the Administrator selects, in the order listed, the highest road-load power, largest displacement, the transmission with the highest numerical final gear ratio (including overdrive), the highest numerical axle ratio offered in that engine family, and the maximum fuel flow calibration. The Administrator selects as the test vehicle the vehicle with the heaviest equivalent test weight (including options) within the family which meets the air conditioning eligibility requirement discussed earlier in this section. If air conditioning is projected to be available on any vehicles within the engine family, the Administrator will limit selections to engine codes which have air conditioning available and will require that any vehicle selected under this section has air conditioning installed and operational. Within each engine family, one test vehicle is selected. (i ) Vehicles are chosen to be operated and tested for emission data based upon engine family groupings. (6) EPA may void ab initio a certificate for a vehicle certified to Tier 1 certification standards or to the respective evaporative and/or refueling test procedure and accompanying evaporative and/or refueling standards as set forth or otherwise referenced in § 86.098–10 for which the manufacturer fails to retain the records required in this section or to provide such information to the Administrator upon request. Where a paragraph in § 86.091–7 or § 86.094–7 is identical and applicable to § 86.000–7, this may be indicated by specifying the corresponding paragraph and the statement “. Section 86.000–7 includes text that specifies requirements that differ from § 86.091–7 or § 86.094–7. § 86.000-7 Maintenance of records submittal of information right of entry.
