Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) The applicant must demonstrate, to the
				  satisfaction of the Executive Officer, the durability of the applicant's LSI
				  retrofit emission control system through an actual field or laboratory-based
				  demonstration test. If the applicant chooses a laboratory-based durability
				  demonstration, an additional field demonstration will be required to
				  demonstrate in-field compatibility (pursuant to Section
				  2785). If the applicant has
				  demonstrated the durability of the identical system in a prior verification or
				  OEM certification, or has demonstrated durability through field experience, the
				  applicant may request that the Executive Officer accept the previous
				  demonstration in fulfillment of this requirement. In evaluating such a request,
				  the Executive Officer may consider all relevant information including, but not
				  limited to, the similarity of baseline emissions and application duty cycles,
				  the relationship between the emission control group or engine family(ies) used
				  in previous testing and the current emission control group, the number of
				  engines tested, evidence of successful operation and user acceptance, and
				  published reports.
(b)
Engine Selection.
Subject to the approval of the Executive
				  Officer, the applicant may choose the engine to be used in the durability
				  demonstration. The engine must be representative of the engines in the emission
				  control group for which verification is sought. The selected engine need not be
				  the same as the engine used for the emission testing (pursuant to Section
				  2783), but if the applicant does
				  use the same engine, the emission testing results may also be used for the
				  zero-hour durability tests.
(c)
Test Fuel.
(1) Except as
				  outlined in (c)(2), the test fuel used shall be consistent with the fuel
				  specifications as outlined in the "California Exhaust Emission Standards and
				  Test Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty
				  Trucks, and Medium- Duty Vehicles," as incorporated by reference in section
				  1961(d). If the
				  engine is tested using the U.S. EPA test fuel, as outlined in 40 CFR Part 1065
				  , the manufacturer shall demonstrate that the emission results are consistent
				  with ARB Test Procedures. Manufacturers can use "commercially available fuels"
				  to accumulate service hours but emission testing must be conducted using test
				  fuel as specified in this section.
(2) Gasoline-fueled, large spark-ignition
				  engines that are tested during the 2013-2019 calendar years have the option of
				  using the test fuel referenced in section
				  2784(c)(3) for
				  demonstrating exhaust emission compliance with the requirements of this
				  section.
(3) Gasoline-fueled, large
				  spark-ignition engines that are tested during 2020 and later calendar years
				  must be exhaust emission tested using a test fuel that is consistent with the
				  fuel specifications as outlined in title 13, section
				  1961.2; and, the "California 2015
				  and Subsequent Model Criteria Pollutant Exhaust Emission Standards and Test
				  Procedures and 2017 and Subsequent Model Greenhouse Gas Exhaust Emission
				  Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and
				  Medium-Duty Vehicles," adopted March 22, 2012, which is incorporated by
				  reference herein. The test fuel specifications should remain consistent from
				  batch to batch. Optionally, manufacturers may use other renewable fuel blends
				  under this paragraph that have been certified by ARB as yielding test results
				  equivalent, or more stringent than, those resulting from the fuel specified by
				  13 CCR
				  1961.2, and which are appropriate for the
				  certification of large spark-ignition engines.
(4) During all engine tests, the engine shall
				  employ lubricating oil consistent with the engine manufacturer's specifications
				  for that particular engine. These specifications shall be recorded and declared
				  in the verification application.
