“Alternate phase-in” is a phase-in schedule that achieves equivalent compliance volume by the end of the last year of a scheduled phase-in provided in this regulation. For alternate-fueled vehicles, the manufacturer shall meet the requirements of section (d)(7.1).

For vehicles with engines that can use more than one type of fuel but can be operated in-use exclusively on gasoline or diesel fuel, the vehicles are considered alternate-fueled vehicles only for the portion of operation the engine uses a fuel other than exclusively gasoline or diesel (e.g., a gasoline and CNG vehicle with an engine that can operate exclusively on gasoline is considered an alternate-fueled vehicle only while operating on CNG and is not subject to the provisions or relief of this regulation for alternate-fueled vehicles while operating exclusively on gasoline). For the purposes of this regulation, alternate-fueled vehicles include vehicles with dedicated alternate-fueled engines (i.e., engines designed to operate exclusively on the alternate fuel) and engines that can use more than one type of fuel but cannot be reasonably operated in-use exclusively on gasoline or diesel fuel (e.g., engines with diesel pilot injection and CNG main injection where engine operation is limited to idle if CNG fuel is not available or engines which use gasoline-only operation during cold start and CNG-only operation for the rest of the driving cycle and engine operation defaults to a limp-home restricted speed and load if CNG fuel is not available). “Alternate-fueled vehicle” refers to a vehicle with an engine using a fuel different from or in addition to gasoline fuel or diesel fuel (e.g., compressed natural gas (CNG), liquefied petroleum gas). For 2024 and subsequent model year vehicles, engine idle stop-start systems are required to be tracked under section (g)(6). For 2004 through 2023 model year vehicles, engine idle stop-start systems are not required to be tracked under section (g)(6).

Compressor 4.2.2 system requirements driver#
or 40 CFR §86.1869-12(b)(1)(viii), as it existed on August 5, 2015, driver-activated technologies where the driver does not have a less efficient selectable option (e.g., high efficiency exterior lights), and technologies related solely to heating, ventilation, and air conditioning for vehicle cabin conditioning. Examples of off-cycle credit technologies that are not required to be tracked under section (g)(6) include non-active technologies such as solar glazing and solar reflective paint, thermal control technologies specified in title 13, CCR section 1961.3(a)(8)(A)1.a. Examples of active off-cycle credit technologies include active aerodynamic features (e.g., grill shutters or ride height that is automatically adjusted by the vehicle control system based on vehicle speed or other conditions), active engine warmup technologies, and driver coaching and/or feedback systems that encourage the driver to alter his/her actions to maximize efficiency.
Compressor 4.2.2 system requirements code#
“Active off-cycle credit technology” refers to a technology that generates off-cycle credits in accordance with title 13, CCR section 1961.3(a)(8) or 40 Code of Federal Regulations (CFR) §86.1869-12 as it existed on August 5, 2015, as applicable, and that must be activated by the vehicle or driver in order to provide a carbon dioxide (CO 2) reduction benefit.
