Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Pursuant to Section
				  43010, Chapter 1, Part 5, Division
				  26 of the Health and Safety Code, exhaust emissions from light-duty (6,000
				  pounds or less gross vehicle weight) and medium-duty (8,500 pounds or less
				  gross vehicle weight) gasoline-powered vehicles subject to inspection pursuant
				  to Chapter 20.4 (commencing with Section
				  9889.50) of Division 3 of the
				  Business and Professions Code shall not exceed the standards set forth in this
				  section by vehicle class as shown in Table 1.
(b) The inspection shall consist of exhaust
				  emission measurements from the vehicle with the air injection system (if any)
				  connected. Hydrocarbon, carbon monoxide, and oxides of nitrogen concentrations
				  shall be determined by non-dispersive infrared instrumentation.
The cruise mode test shall be performed first on a chassis
					 dynamometer at the speeds and loads shown in the following table:

							 of Cylinders

A vehicle which cannot reach the speed and load specified
					 in the table above, or which by its original design cannot be tested at cruise
					 on an inspection center dynamometer, may be exempted from the cruise mode of
					 the test. Vehicles owned by licensed fleet operators may be exempted from
					 cruise mode test, provided an underhood functional inspection is performed on
					 these vehicles, in addition to idle mode test. An idle mode test may be
					 performed on vehicles at one lane inspection centers wherever dynamometers are
					 inoperative.
The idle mode test shall be performed with the transmission
					 set in neutral gear with the engine at its normal operating temperature. The
					 cruise mode test shall be performed with automatic transmission in drive and
					 with manual transmission set in high gear but overdrive will be
					 disengaged.
(c) In the event
				  of a conflict between the emission standards set forth in subdivision (a) and a
				  manufacturer's specifications for a particular engine family or group of
				  vehicles (defined by make, model year, and emission control system), as
				  demonstrated by an excessive failure rate, by valid assembly-line data of the
				  vehicle manufacturer, or by other data available to the executive officer, the
				  executive officer may by Executive Order exempt such engine families or groups
				  of vehicles from the standards set forth in subdivision (a) and set appropriate
				  separate emission standards.
