An emissions inspector must meet what requirements? - ANSWER Be at least 18 years of
age
Have a valid driver's license
To deliver emissions waivers you must become a(n)... - ANSWER emissions Certified Re-
pair Technician (CRT)
To become a CRT you must... - ANSWER Have a valid driver's license
What is the Northern-Emission Inspectors Certification program? - ANSWER Limited to
performing the visual antitampering check and gas-cap test.
Upon successful completion of the N-EIC program you will receive.. - ANSWER An emis-
sions inspection ID card from PennDOT that allows you to perform inspections on vehicles
registered in the Northern Region counties only.
Air pollution - ANSWER Contamination of the atmosphere by gaseous, liquids or solid
wastes or byproducts. Emitted from natural or human-made sources.
1
, Most of the world's air pollution problems are... - ANSWER Human-made
Major Pollutants - ANSWER Hydrocarbons (HCs), carbon monoxide (CO), and nitrogen ox-
ides (NOx). (released from fossil fuels like gasoline and diesel)
Hydrocarbons - ANSWER Unburned fuel of any class of organic compounds composed of
carbon and hydrogen
Carbon Monoxide - ANSWER Colorless, odorless, and poisonous gas. Created when an
engine burns HV in the presence of O2.
Oxygen - ANSWER Too much or too little can cause improper combustion and result in
pollution
Ozone (Smog) - ANSWER Not emitted directly into the air, it is created at ground level by
a chemical reaction between NOx and HC in the presence of sunlight .
Nitrogen Oxides (NOx) - ANSWER Excessive amounts can be caused by a lean air-fuel mix-
ture, a defective exhaust gas recirculation valve, higher than normal engine temperatures,
vacuum leaks, and advanced ignition timing.
Five Gas Theory - ANSWER The relationship between HC, CO, O2, CO2, and NOx are the
same in all gasoline engines.
Stoichiometric Ratio - ANSWER For all engines, a mixture of approx. 14.7 parts of air to
every one-part of fuel produces the most efficient use of fuel and the lowest emissions.
Why would hydrocarbon be higher than the stoichiometric ratio? - ANSWER The mixture
is very rich or very lean. Normal combustion is 15:1 air/fuel ratio.
