SMOG TEST QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS ALREADY PASSED!!!
1. Smog Check Exemptions and Regulations
Q: All of the following vehicles are exempt from a smog check inspection,
EXCEPT: A: Rotary powered vehicles.
Explanation: While many vehicles (such as electric, hybrid, or classic cars
built before 1975) qualify for exemptions, rotary-powered vehicles are
subject to the same emissions inspection requirements as any other internal
combustion engine vehicle.
Q: Technician A states the BAR-97 EIS may be used outside the station
building when inspecting a heavy-duty vehicle. Technician B states the EIS
shall not be used outside the station building but may be connected to a large
vehicle located outside the building. Who is correct? A: Technician B.
Explanation: To maintain the integrity of the testing environment and
ensure the equipment is properly protected, BAR regulations strictly prohibit
the use of the EIS (Emission Inspection System) unit outside of the approved
building area. It must remain indoors.
2. Functional Inspections
Q: The under-hood emission label states that ignition timing is 8° BTDC
(Before Top Dead Center), and the timing is adjustable. Under which
condition will this vehicle fail the functional inspection? A: The ignition
timing check reads 2° BTDC.
Explanation: The timing must be within the manufacturer's specified range.
A reading of 2° BTDC is outside the acceptable tolerance for a factory
specification of 8° BTDC. Deviating from the label-specified timing can
drastically alter tailpipe emissions.
