YOUR TEST RESULTS
THANK YOU FOR BRINGING YOUR VEHICLE TO OUR INSPECTION CLINIC.
The results of an idle exhaust emissions test indicate that your vehicle's emissions are:
| HYDROCARBONS (HC):_____________________ (ppm) | PASS FAIL |
| CARBON MONOXIDE (CO):__________________ (%) | PASS FAIL |
Compare these to the limits listed in the table below to determine if your vehicle is above or below the idle emissions limits for it's model age, vehicle type, and engine size.
HYDROCARBON emissions consist primarily of unburned gasoline. CARBON MONOXIDE emissions result from the incomplete burning of gasoline. Higher than acceptable levels of carbon monoxide or hydrocarbon emissions may be caused by either fuel/air ratio problems or by missing or malfunctioning emissions control systems.
If your vehicle's emissions were judged to be high, we suggest that you have the vehicle checked at a service establishment that is familiar with the proper maintenance and operation of your vehicle including the emissions control systems. A vehicle's performance is optimum when it has been maintained according to the manufacturer's maintenance schedule (usually described in the owner's manual). A well-maintained vehicle will run better and generally have better fuel economy and lower emissions of harmful air pollutants.
Possible reasons for high emissions levels are:
- Ignition system problems possibly related to timing, spark plugs, plug wires, coil, electronic spark control, etc.
- Idle mixture too rich or too lean.
- Dirty air filter.
- Faulty positive crankcase ventilation (PCV) system.
- Faulty catalytic converter.
- Faulty exhaust gas recirculation (EGR) valve operation.
- Faulty oxygen (O2) system and/or computer system.
- Carburettor or fuel injection system maladjustment or malfunction.
- Faulty air injection system.
- Vacuum leak(s) in the engine intake system and hoses.
- Carbon deposits in engine.
- Worn engine.

YOUR VEHICLES FUEL CAP
Hydrocarbons can escape from the gas tank if the fuel cap does not provide an adequate seal.

YOUR VEHICLE AND CLIMATE CHANGE
Climate change is a shift in the "average weather" that a given region experiences. This is measured by changes in all the features we associate with weather, such as temperature, wind patterns, precipitation, and storms. Carbon dioxide (CO2) is the most important green house gas produced by humans and it is the major contributor to climate change - especially through the burning of fossil fuels when we drive, heat homes and other buildings or run our industries.
Your vehicle may have passed the test on HC and CO emissions, however, all vehicles produce CO2 emissions during the combustion process. Although the amount of CO2 emissions produced by your vehicle cannot be measured at this clinic, it is directly related to your vehicle's fuel consumption. Keeping your vehicle well maintained will decrease your fuel consumption. Other ways of reducing the amount of CO2 your vehicle releases into the atmosphere are to buy a vehicle that is more fuel-efficient, drive less, use alternative means of transportation, keep your tires properly inflated and practice good driving habits.
HOW DOES YOUR VEHICLE MEASURE UP?
Included in your information package is a brochure called "All About Driving Smarter" that shows how you can obtain a variety of publications from Natural Resources Canada on driving smarter, or you can visit the Auto$mart web site at "autosmart.nrcan.gc.ca".
YOUR VEHICLE'S ANNUAL CO2 PRODUCTION
Based on the amount of fuel that you use per week, we have calculated your vehicle's annual CO2 production to be approximately: ______________________ tonnes.
YOUR VEHICLE'S TIRE PRESSURE
Each 5% (typically 14 kPa or 2 psi) of underinflation translates into 1% of increased fuel consumption. Both overinflation and underinflation can lead to premature wear on your tires, can waste fuel and are unsafe. Check your tire pressure frequently and keep your tires inflated to the pressure specified by the vehicle manufacturer. If a recommended range is given, use the higher pressure.
Your vehicle's recommended tire pressure: Front ______________ psi Rear ______________ psi
