Station Hotline (888) 265-5909 Customer Hotline (800) 265-0921 Sticker Department (717) 705-2182 An emissions inspector must meet what requirements? Be at least 18 years of age Have a valid driver's license To deliver emissions waivers you must become a(n)... emissions Certified Repair Technician (CRT) To become a CRT you must... Have a valid driver's license What is the Northern-Emission Inspectors Certification program? Limited to performing the visual antitampering check and gas-cap test. Upon successful completion of the N-EIC program you will receive.. An emissions inspection ID card from PennDOT that allows you to perform inspections on vehicles registered in the Northern Region counties only. Air pollution Contamination 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... Human-made Major Pollutants Hydrocarbons (HCs), carbon monoxide (CO), and nitrogen oxides (NOx). (released from fossil fuels like gasoline and diesel) Hydrocarbons Unburned fuel of any class of organic compounds composed of carbon and hydrogen Carbon Monoxide Colorless, odorless, and poisonous gas. Created when an engine burns HV in the presence of O2. Oxygen Too much or too little can cause improper combustion and result in pollution Ozone (Smog) 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) Excessive 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 The relationship between HC, CO, O2, CO2, and NOx are the same in all gasoline engines. Stoichiometric Ratio 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? The 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? It runs rich, meaning combustion forms more CO and less CO2. What does it mean if Hc is high and CO is extremely low? The engine is either very lean or there's a misfire. What does it mean if CO is very high? The engine is definitely rich, getting too much fuel or not enough air. Why is oxygen the best lean indicator? The levels change during lean mixtures. Why is oxygen (O2) not a reliable rich indicator? It is low whenever the mixture is rich. Rich mixtures burn all available O2. When did PA implement itd first emissions I/M program? 1984 In 1990 Congress set the requirements for an enhanced program in the Clean Air Act Amendments which aimed to do what? Lower harmful emissions and increase accountability at the state level. What was the 1992 EPA mandate in accordance with the Clean Air Act? PA 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? Tailpipe testing of vehicle exhaust emissions Our goal? Clean air, PA emissions inspection program is part of the state's plan to clean the air and keep it clean in the future. Subject Vehicles Vehicles of model year 1975 and newer, having a gross vehicle weight rating of 9,000 lbs or less. Gasoline powered buses that seat 15 or fewer and have a GVWR of 9,000 lbs or less are also required to undergo emissions testing. Non-subject Vehicles Classic, antique, specially constructed, or collectible motor vehicles (titles/registered as such). Buses with a seating capacity of 16 or more. Vehicles with a GVWR of 9,001 lbs or more 1974 and older model year vehicles Vehicle exemptions New or current model year subject vehicles that have never been registered in PA or any other jurisdiction before the current owner, and have less than 5,000 miles on the odometer. Vehicles driven less than 5,000 miles in the previous 12 months that have been owned by the same person for a minimum of 1 year. What do you do if a vehicle qualifies for exemption? Only verify that the odometer is operation DO NOT do any other visual inspections. Customer is refusing to authorize an I/M test? You may refuse to perform his/her safety inspection. Leased Vehicles are subject to... Emissions inspection based on the county listed on the registration card. Can out-of-state vehicles entering PA with a cardboard transportation tag be tested? Yes! as long as the vehicle can legally be driven on the highway. Vehicle owners need to apply for registration within 20 days of entering PA. There are two main forms that are presented to a customer following an inspection... Passing = one form Failing = two forms What is the form given if a vehicle fails inspection? The repair data form to complete and return upon re-inspection (should be completed regardless of who performs the repairs). What are the rules when a customer challenges an I/M result? Must be made within 10 days of the date on which the vehicle failed. If vehicle passes, an emissions sticker must be issued for the vehicle and must not be charged. Customer must pay if the retest fails. When is proof of insurance required? Not for emissions but it is required for safety inspection.
