SUBPART B: VEHICLE EMISSIONS INSPECTION PROCEDURES

Section 276.201 General Description of Vehicle Emissions Inspection Procedures

Compliance with vehicle exhaust, evaporative emissions, on-board diagnostics, and on-road sensing standards shall be determined by use of test procedures and other requirements as applicable as set forth in this Part, and shall be performed to the extent practicable.

(Source: Amended at 26 Ill. Reg. 8113, effective May 17, 2002)

Section 276.202 Pollutants to be Tested – Exhaust Test

Vehicle exhaust emission inspections shall consist of sampling vehicle tailpipe emissions of HC, CO, CO₂, and NO_x (if applicable).

(Source: Amended at 22 Ill. Reg. 18867, effective September 28, 1998)

Section 276.203 Dilution - Steady-State Idle Exhaust Test and Transient Loaded Mode Exhaust Test

a)	Steady-State Idle Exhaust Test
	To prevent excess dilution in a steady-state idle exhaust emissions test described in Section 276.204, the sample probe shall be inserted a minimum of 10 inches into the vehicle's tailpipe. Extension boots shall be utilized if it is impossible to insert the sample probe at least 10 inches into the tailpipe. A vehicle emission test shall be invalid if the applicable emission standards contained in 35 Ill. Adm. Code 240 are met but the sum of the CO and CO₂concentrations in the exhaust gas does not exceed 6 percent during the sample averaging period(s).
b)	Transient Loaded Mode Exhaust Test
	To prevent excess dilution in a transient loaded mode exhaust emissions test described in Section 276.207, the exhaust collection system shall be positioned to insure complete capture of the entire exhaust stream from the tailpipe during the transient driving cycle. The test system shall verify that the entire exhaust stream is being collected through continuous monitoring of exhaust CO₂generated during the transient driving cycle and comparison with theoretical levels of exhaust CO₂ produced by the vehicle being tested. A vehicle emission test shall be invalid if the measured values fall below expected values during the transient driving cycle. At a minimum, the emission test shall be invalid if five consecutive one-second average CO₂ values fall below 0.085 percent during seconds 5 through 220 of the transient driving cycle.

Section 276.204 Steady-State Idle Exhaust Emissions Test Procedures

a)	Steady-State Idle Test

1)	Test Description
	The steady-state idle test with loaded preconditioning may be substituted for the transient loaded mode exhaust gas analysis for those vehicles identified in Section 13B-25(c) and (d) of the Vehicle Emissions Inspection Law of 1995. The steady-state idle test with loaded preconditioning consists of a first-chance idle mode test followed, if necessary, by a second-chance test. The second-chance test consists of a loaded preconditioned mode using a dynamometer, or a high idle preconditioned mode while in neutral or park, followed immediately by an idle mode.
2)	Engine Re-Start
	In addition to the test procedures of this Section, the engines of 1981-1987 model year Ford Motor Company vehicles and 1984-1985 model year Honda Preludes must be shut off for not more than 10 seconds and restarted prior to initiating the idle mode of the second-chance test. The probe shall be removed from the tailpipe or the sample pump turned off if necessary to reduce analyzer fouling during the restart procedure.

b)	General Requirements

1)	Initial tests (i.e., those occurring for the first time in a vehicle's scheduled test cycle) shall be performed without repair or adjustment at the inspection facility prior to the test.

B)	If the vehicle passes one test and fails the other test, then the test results from the passing test shall be provided.
C)	If the vehicle fails both tests, then the test results from the second test shall be provided.

e)	Vehicle Emission Test Sequence

1)	Transient Driving Cycle

The vehicle shall be driven over the driving cycle contained in Section 276.Table A of this Part.

2)	Driving Trace

The inspector shall follow an electronic, visual depiction of the time/speed relationship of the transient driving cycle (hereinafter, the trace). The visual depiction of the trace shall be of sufficient magnification and adequate detail to allow accurate tracking by the driver and shall permit the driver to anticipate upcoming speed changes. The trace shall also clearly indicate gear shifts as specified in subsection (e)(3) of this Section.

3)	Shift Schedule

For vehicles with manual transmissions, inspectors shall shift gears according to the following shift schedule:

Shift Sequence Gear	Approximate Speed Miles Per Hour	Nominal Cycle Time Seconds

1-2	15	9.3
2-3	25	47.0
De-clutch	15	87.9
1-2	15	101.6
2-3	25	105.5
3-2	17	119.0
2-3	25	145.8
3-4	40	163.6
4-5	45	167.0
5-6	50	180.0
De-clutch	15	234.5

Gear shifts shall occur at the points in the driving cycle where the specified speeds are obtained. For vehicles with fewer than 6 forward gears, the same schedule shall be followed with shifts above the highest gear disregarded.

4)	Speed excursion limits shall apply as follows:

A)	The upper limit is 2 mph higher than the highest point on the trace within 1 second of the given time.
B)	The lower limit is 2 mph lower than the lowest point on the trace within 1 second of the given time.
C)	Speed variations greater than the tolerances (such as may occur during gear changes) are acceptable provided that they occur for no more than 2 seconds on any occasion.
D)	Speeds lower than those prescribed during the underpowered intervals of seconds 4 through 18, 97 through 115, and 154 through 219 of the trace will allow the station supervisory personnel the option of overriding the automatic void of the test. As part of the override, the station supervisory personnel will be required to witness a second trace.

i)	During the station supervisory personnel's witness of the second or subsequent trace, the test will be aborted if a speed variation exists for more than two seconds on any occasion outside the underpowered intervals. If this condition is detected, the test shall be stopped, and may be restarted, or aborted and rejected.
ii)	If a speed lower than those prescribed during the underpowered intervals is detected, the vehicle will have the opportunity to regain the test trace speed. Once the test trace speed is attained, the vehicle will be required to meet the speed excursion limitations for the entirety of the trace, outside the underpowered intervals.
iii)	Station supervisory personnel overrides can be used to accept the results of the witnessed second or subsequent trace(s) if the override is flagged with a trace statistic or distance error so long as it meets the requirements specified in subsections (e)(4)(D)(i) and (e)(4)(D)(ii).

E)	The test shall be aborted and immediately restarted if speed excursion limits are exceeded, except as described in subsection (e)(4)(D) of this Section.

5)	Speed Variation Limits

The speed variation limits shall be determined by one of the following methods:

A)	Linear Regression Method

i)	A linear regression of feedback value on reference value shall be performed on each transient driving cycle for each speed using the method of least squares, with the best fit equation having the form: y = mx + b, where:

y	=	The feedback (actual) value of speed
m	=	The slope of the regression line
x	=	The reference value
b	=	The y-intercept of the regression line


ii)	The SE of y on x shall be calculated for each regression line. A transient driving cycle lasting the full 240 seconds that exceeds the following criteria shall be void and the test shall be repeated:

SE	=	2.0 mph maximum
m	=	0.96 - 1.01
r²	=	0.97 minimum
b	=	2.0 mph


iii)	A transient driving cycle that ends before the full 240 seconds that exceeds the following criteria shall be void and the test shall be repeated:

SE	=	(Reserved)
m	=	(Reserved)
r²	=	(Reserved)
b	=	(Reserved)

B)	Positive Kinetic Energy (PKE) Method

i)	The speed variation limits shall be determined by the following equation for Positive Kinetic Energy (PKE):

PKE	=	N	/	x	x	dx
		Σ PP_t		INT
		t=0		0

where:
	PP_t	=	V²_t - V²_t-1mi²/hr² for V_t > V_t-1
	PP_t	=	0 for V_t≤ 0
	x	=	distance (miles)
	PP_t	=	Positive Specific Power at time t
	V_t	=	Velocity at time t
	V_t-1	=	Velocity at time t-1


ii)	A transient driving cycle lasting the full 240 seconds with a PKE value that is below the lower PKE limit for passing vehicles or above the upper limit for failing vehicles shall be void and the test shall be repeated:

Upper Limit: PKE > 3456 mi/hr²
Lower Limit: PKE < 3082 mi/hr²

iii)	A transient driving cycle that ends before the full 240 seconds with a PKE value that is below the lower second-by-second PKE limit for passing vehicles or above the upper second-by-second PKE limit for failing vehicles shall be void and the test shall be repeated. The second-by-second upper and lower PKE limits are specified in Section 276.Table B.
iv)	PKE values shall not be used to make early pass/fail determination.

6)	The actual distance traveled for the transient driving cycle shall be measured. If the absolute difference between the measured distance and the theoretical distance for the actual test exceeds 0.05 miles, the test shall be void and shall be repeated.
7)	The vehicle shall be rejected if, during the course of the transient loaded mode test, station supervisory personnel verify that the test cannot be completed due to the mechanical condition of the vehicle.
8)	Inertia Weight Selection
	Operation of the inertia weight selected for the vehicle shall be verified as specified in Section 276.506(a) of this Part. For systems employing electrical inertia simulation, an algorithm identifying the actual inertia force applied during the transient driving cycle shall be used to determined proper inertia simulation.
9)	The CVS operation shall be verified for each test for a CFV-type CVS by measuring either the absolute pressure difference across the venturi or measuring the blower vacuum behind the venturi for minimum levels needed to maintain choke flow for the venturi design. The operation of an SSV-type CVS shall be verified throughout the test by monitoring the difference in pressure between upstream and throat pressure. The minimum values shall be determined from system calibrations. Monitored pressure differences below the minimum values shall void the test, and a test lane system lockout shall be initiated. No further testing shall be done until the problem is corrected by station supervisory personnel. At Official Inspection Stations, the vehicle involved shall be immediately retested in a properly operating lane.

f)	Transient Loaded Mode Exhaust Gas Test Score Calculations
	The transient loaded mode exhaust gas test score shall be determined according to the method specified in 40 CFR 85.2205(b) (Draft), incorporated by reference in Section 276.104(a) of this Part, with the following exceptions:

1)	The Phase 2 scores for the test shall be determined by dividing the sum of the mass of each pollutant obtained in each second of the Phase 2 test by the number of miles driven in the Phase 2 test. The first data point is the sample taken from t=94 to t=95. The Phase 2 test score shall be determined by the following equation:

Phase 2 gpm	=	s
		Σ	grams of emissions
		t=94
		s
		Σ	miles traveled
		t=94

Where

s = duration of test in seconds for fast pass, or

	s = 239 seconds for complete transient loaded mode exhaust gas test.

2)	NO_xe = nitrogen oxide concentration of the dilute exhaust sample as
		measured in ppm and multiplied by 1.03.

NO_xd = background nitrogen oxide concentration of the dilution air,

sampled as described in 40 CFR 85.2221(b)(5) (Draft), incorporated by reference in Section 276.104(a) of this Part, as measured in ppm and multiplied by 1.03.

g)	Pass/Fail Determination

Compliance with the transient loaded mode exhaust emission test shall be made in accordance with the standards contained in 35 Ill. Adm. Code 240, Subpart E.

1)	On each operating day, analyzers shall successfully pass a two-point gas calibration for HC, CO, and CO₂ and shall continually compensate for changes in barometric pressure. Calibration shall be checked within 4 hours before the test and the analyzer adjusted if the reading is more than 2 percent different from the span gas value. Gas calibration shall be accomplished by introducing span gas that meets the requirements of subsection (e)(3) of this Section into the analyzer through the calibration port. If the analyzer reads the span gas within the allowable tolerence range (i.e., the square root sum of the squares of the span gas tolerance described in subsection (e)(3) of this Section and the calibration tolerance, which shall be equal to 2 percent), no adjustment of the analyzer is necessary. The gas calibration procedure shall correct readings that exceed the allowable tolerance range to the center of the allowable tolerance range. The pressure in the sample cell shall be the same with the calibration gas flowing during calibration as with the sample gas flowing during sampling. If the system is not calibrated, or the system fails the calibration check, the analyzer shall lock out from testing.
2)	A two point gas calibration procedure shall be followed. The span shall be accomplished at one of the following pairs of span points:

Low

300 – ppm propane (HC)
1.0 – percent CO
6.0 – percent CO[2]
1000 – ppm nitric oxide (if equipped with NO)

High
1200 – ppm propane (HC)
4.0 – percent CO
12.0 – percent CO[2]
3000 – ppm nitric oxide (if equipped with NO)

Low

0 – ppm propane (HC)
0.0 – percent CO
0.0 – percent CO [2]
0 – ppm nitric oxide (if equipped with NO)

High
600 – ppm propane (HC)
1.6 – percent CO
11.0 – percent CO[2]
1200 – ppm nitric oxide (if equipped with NO)

3)	The span gases used for the gas calibration shall be traceable to NIST standards within two percent and shall be within two percent of the span points specified in subsection (e)(2) of this Section.

f)	Other Checks

In addition to the other periodic checks described in this Section, those described in subsections (f)(1) and (f)(2) of this Section shall also be used to verify system performance under the special circumstances described therein.

1)	Gas Calibration

A)	Each time the analyzer electronic or optical systems are repaired or replaced, a gas calibration shall be performed prior to returning the unit to service.
B)	Monthly multi-point calibrations shall be performed. The calibration curve is checked at 20 percent, 40 percent, 60 percent, and 80 percent of full scale, and must be adjusted or repaired if the specifications in Section 276.503 are not met.

2)	Leak Checks

Each time the sample line integrity is broken, a leak check shall be performed prior to testing.
