What’s the difference between “Safety Inspections” and “Emissions Inspections”?, That’s a good question, let’s shed some light on the subject.
“Briefly, of course, to let you get back to your busy day.”
Without getting into the history of Safety Inspections (we covered that one already) or the term “Safety” (It goes without saying) and we included that one already as well, we will focus mainly on Emissions.
Older vehicles with high miles or older vehicles in the specific year ranges (ask your location manager), only require safety inspections, cars with modern emissions technologies must have the Emissions Inspection.
The Inspection station location manager of your choice can explain in more detail which one you need, in the meantime and to help you, let's get right into it.
The internal combustion engine in its purest form is a controlled explosion (small bomb if you will) inside a chamber (your motor), a gas (fumes create the explosion.
/vapor) and air mixture, the spark will ignite this mixture. This explosion (when completed) creates a by-product (Hydro Carbons), your car's engine has components that manage these by-products (Hydro Carbons) before they leave the exhaust system (your mufflers).
The two significant breakthrough's handling these carbons were: The “Smog Pump” and the “Catalytic Converter.” Today there are many more components and advancements in technologies to control these vapors.
Smog Pump - A pump that generated compressed air, it aimed towards the exhaust outlet (of the combustion chamber inside your engine aka, cylinder) and forced it back into the burn cycle to be re-burnt, lessening the amount introduced into the air we breathe.
Catalytic Converter - The Hydro Carbons that did manage to escape are passed through the Converter and filtered (chemically altered) even more, thus reducing the HydroCarbons.
Reduced into layman's terms so we can understand, the essential components, these components must be checked to be sure they are working correctly. Unfortunately, visual inspections rarely work. Therefore a sensor (computer) must be part of the equation.
So in conclusion: Safety, are your lights, horn, brakes, tires, and other things that could cause an accident. Emissions are the components that reduce pollutants and could also create a severe vapor accident.
