(1) Exhaust gas measurement calculation.
(i) System response time
The analysis and recording of exhaust gas concentrations shall begin 12 seconds after the applicable test mode begins, or sooner if the system response time is less than 12 seconds. The analyzing and recording of exhaust gas concentrations shall not begin sooner than the time period equivalent to the response time of the slowest transducer.
(ii) Sample rate
Exhaust gas concentrations shall be analyzed at a minimum rate of once per second.
(iii) Emission measurement calculations.
Partial stream (concentration) emissions shall be calculated based on a running 10-second average. The values used for HC(J), CO(J), and NO(J) are the raw (uncorrected) tailpipe concentrations.
(c)
(iv) Dilution correction factor.
The analyzer software shall multiply the raw emissions values by the dilution correction factor (DCF) during any valid ASM emissions test. The DCF accounts for exhaust sample dilution (either intentional or unintentional) during an emissions test. The analyzer software shall calculate the DCF using the following procedure, and shall select the appropriate vehicle fuel formula. If the calculated DCF exceeds 3.0 then a default value of 3.0 shall be used.
(a)
Where [CO2]MEASURED and [CO]MEASURED are the instantaneous ASM emissions test readings.
(b) Calculate [CO2]adjusted using the following formulas.
(1) For gasoline:
(2) For Methanol or Ethanol:
(3) For Compressed Natural Gas (CNG):
(4) For Liquid Propane Gas (LPG):
(c) Calculate the DCF using the following formula.
(v) Kh = No humidity correction factor.
(a)
(b) H = Absolute humidity in grains of water per pound of dry air.
(c) RA = Relative humidity of the ambient air percent.
(d) PD = Saturated vapor pressure, MM HG at the ambient dry bulb temperature. If the temperature is above 86°F, then it shall be used in lieu of the higher temperature, until EPA supplies final correction factors.
(e) PB = Barometric pressure, MM HG.
(2) Pass/fail determination.
A pass or fail determination shall be made for each applicable test mode based on a comparison of the applicable short test standards and the measured value for HC, CO, and NO as described in Paragraph (b)(1)(iii) of this section. A vehicle shall pass the test mode if the emission values for HC, CO, and NO are simultaneously below or equal to the applicable short test standards for all three pollutants. A vehicle shall fail the test mode if the values for HC, CO, or NO, or any combination of the three, are above the applicable standards at the expiration of the test time.
§ 2. ASM short test procedure.
(a) General requirements
(1) Vehicle characterization.
(i) Vehicle type: LDGV, LDGT1, LDGT2, HDGT, and others as needed;
(ii) Chassis model year;
(iii) Make;
(iv) Model;
(v) Number of cylinders;
(vi) Cubic inch or liters displacement of the engine;
(vii) Transmission type; and
(viii) Equivalent test weight.
(2) Ambient conditions.
The ambient temperature, relative humidity and barometric pressure shall be recorded continuously during the test cycle or as a single set of readings up to 4 minutes before the start of the driving cycle.
(3) Restart.
If shut off, the vehicle shall be restarted as soon as possible before the test and shall be running at least 30 seconds prior to the start of the ASM driving cycle.
(4) Void test conditions.
The test shall immediately end and any exhaust gas measurements shall be voided if the instantaneous measured concentration of CO plus CO2 falls below 6% or the vehicle's engine stalls at any time during the test sequence.
(5) Test time limit.
The test shall be aborted or terminated upon reaching the overall maximum test time.
(b) Pre-inspection and preparation.
(1) Accessories.
All accessories (air conditioning, heat, defogger, radio, automatic traction control if switchable, and the like) shall be turned off (if necessary, by the inspector).
(2) Exhaust leaks.
The vehicle shall be inspected for exhaust leaks by test personnel. Audio assessment while blocking exhaust flow shall be acceptable. Vehicles with leaking exhaust systems shall be rejected from testing.
(3) Fluid leaks.
Vehicles with excessive leaking engine oil, transmission fluid or coolant shall be rejected from testing.
(4) Mechanical condition.
Vehicles with obvious mechanical problems (engine, transmission, brakes or exhaust) that either create a safety hazard or could bias test results shall be rejected from testing.
(5) Operating temperature.
The vehicle shall be at proper operating temperature prior to the start of the test. The vehicle temperature gauge, if equipped and operating, shall be checked to assess temperature. Vehicles in overheated condition shall be rejected from testing.
(6) Tire condition.
Vehicles shall be rejected from testing if tread indicators, tire cords, bubbles, cuts or other damage are visible. Vehicles shall be rejected from testing if they have space-saver spare tires or if they do not have reasonably sized tires on the drive axle or axles. Vehicles may be rejected if they have different sized tires on the drive axle or axles. In test-and-repair facilities, drive wheel tires shall be checked with a gauge for adequate tire pressure. In test-only facilities, drive wheel tires shall be visually checked for adequate pressure level. Drive wheel tires that appear low shall be inflated to approximately 30 PSI, or to tire side wall pressure, or vehicle manufacturer's recommendation. Alternatively, vehicles with apparent low tire pressure may be rejected from testing.
(7) Emission sample system purge/hang-up.
While a lane is in operation, the sample system shall be continuously purged after each test for at least 15 minutes if not taking measurements. If the HC reading, when the probe is sampling ambient air, exceeds 7 PPM C6 on an instantaneous measure, testing shall be prohibited. Testing may proceed after a determination is made that hang-up is less than 7 PPM C6 (that is, by eliminating the ambient background contribution to the measurement).
(8) Roll rotation.
The vehicle shall be maneuvered onto the dynamometer with the drive wheels positioned on the dynamometer rolls, prior to restraining the vehicle and test initiation. The rolls shall be rotated until the vehicle laterally stabilizes on the dynamometer. Vehicles that cannot be stabilized on the dynamometer shall be rejected from testing. Drive wheel tires shall be dried if necessary to prevent slippage.
(9) Cooling system.
When ambient temperatures exceed 72°F, testing shall not begin until the cooling system is positioned and activated. The cooling system blower shall be positioned to direct air to the vehicle cooling system, but shall not be directed at the catalytic converter.
(10) Vehicle restraint.
Testing shall not begin until the vehicle is restrained. Any restraint system shall meet the requirements of § 3(a)(5)(ii). In addition, the parking brake shall be set for front wheel drive vehicles prior to the start of the test, unless parking brake functions on front axle or if it is automatically disengaged when in gear.
(11) Dynamometer warm-up.
The dynamometer shall be in a warmed-up condition prior to official testing and use shall be locked out until it is warmed up. Dynamometers resting (not operated for at least 30 seconds and at least 15 mph) for more than 30 minutes shall pass the coast-down check specified in § 4(b)(1) prior to use in testing. Control charts may be used to demonstrate the need for less frequent warm- up.
Testing cannot occur below 41°F.
(12) Analyzer warm-up.
An emissions test shall not begin before the analyzer has been adequately warmed up. Turning on the analyzer for a time period of at least 4 times the period of time required to reach stability as demonstrated in the equipment certification (see § 7) shall constitute ''warmed-up.''
(c) Test sequence.
(1) The test sequence shall consist of a single ASM mode described in § 2(d) of this subpart. Vehicles that fail the first chance test as described in § 2(d) of this subpart shall receive a second chance test under § 2(e) of this subpart. The second chance test shall consist of a repetition of the mode or modes that were failed in the first chance test according to the conditions in § 2(e) of this subpart.
(2) The test sequence shall begin only after the following requirements are met:
(i) Load setting.
Prior to each mode, the system shall automatically select the load setting of the dynamometer from a supplied look-up table.
(ii) Accessories.
The vehicle shall be tested in as-received condition with all accessories turned off. The engine shall be at normal operating temperature.
(iii) Gear selection.
