Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
Emission Control Group
.
				  The applicant must identify the emission control group and test the LSI
				  retrofit emission control system on representative engines from that emission
				  control group. The applicant must identify the test engines, and equipment if
				  applicable, by providing the engine family name, if available, make, model, and
				  model year. The applicant must also describe equipment applications on which
				  the LSI retrofit emission control system is intended to be used, by giving
				  examples of in-use equipment, characterizing typical duty cycles, indicating
				  any fuel requirements, and/or providing other application-related
				  information.
(b)
Engine
				  Pre-conditioning.
All testing should be performed with the test engine
				  in a proper state of maintenance. The applicant may tune-up or rebuild the test
				  engine prior to, but not after, baseline testing, unless rebuilding the engine
				  is a part of the requirements for installation of the LSI retrofit emission
				  control system.
(c)
LSI
				  Retrofit System Pre-conditioning.
The engine or equipment installed
				  with an LSI retrofit emission control system must be operated for a break-in
				  period of between 25 and 100 hours before emission testing.
(d)
Test Fuel.
(1) 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 these Test Procedures.
(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 2783(d)(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.
