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
Repair 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.. - answerAn
emissions inspection ID card from PennDOT that allows you to perform inspections on
vehicles registered in the Northern Region counties only.

Air pollution - answerContamination of the atmosphere by gaseous, liquids or solid
wastes or byproducts. Emitted from natural or human-made sources.

Most of the world's air pollution problems are... - answerHuman-made

Major Pollutants - answerHydrocarbons (HCs), carbon monoxide (CO), and nitrogen
oxides (NOx). (released from fossil fuels like gasoline and diesel)

Hydrocarbons - answerUnburned fuel of any class of organic compounds composed of
carbon and hydrogen

Carbon Monoxide - answerColorless, odorless, and poisonous gas. Created when an
engine burns HV in the presence of O2.

Oxygen - answerToo much or too little can cause improper combustion and result in
pollution

, Ozone (Smog) - answerNot 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) - answerExcessive amounts can be caused by a lean air-fuel
mixture, a defective exhaust gas recirculation valve, higher than normal engine
temperatures, vacuum leaks, and advanced ignition timing.

Five Gas Theory - answerThe relationship between HC, CO, O2, CO2, and NOx are the
same in all gasoline engines.

Stoichiometric Ratio - answerFor 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? - answerThe mixture is
very rich or very lean. Normal combustion is 15:1 air/fuel ratio.

What happens when there is not enough O2 in an engine? - answerIt runs rich,
meaning combustion forms more CO and less CO2.

What does it mean if Hc is high and CO is extremely low? - answerThe engine is either
very lean or there's a misfire.

What does it mean if CO is very high? - answerThe engine is definitely rich, getting too
much fuel or not enough air.

Why is oxygen the best lean indicator? - answerThe levels change during lean mixtures.

Why is oxygen (O2) not a reliable rich indicator? - answerIt is low whenever the mixture
is rich. Rich mixtures burn all available O2.

When did PA implement itd first emissions I/M program? - answer1984

In 1990 Congress set the requirements for an enhanced program in the Clean Air Act
Amendments which aimed to do what? - answerLower harmful emissions and increase
accountability at the state level.

What was the 1992 EPA mandate in accordance with the Clean Air Act? - answerPA
required a vehicle emissions I/M program be implemented to increase air quality and
decrease pollution.

In 1997 PennDOT implemented an enhanced decentralized vehicle emissions
inspection program that featured what? - answerTailpipe testing of vehicle exhaust
emissions

Our goal? - answerClean air, PA emissions inspection program is part of the state's plan
to clean the air and keep it clean in the future.
