What is a "Smog Inspection" and How to Pass One Successfully
Smog inspections are necessary to ensure we are doing the best we can to create a better environment and are safe in our vehicles. In our modern world, there are several environmental issues that are so vital to consider. Smog is a major one that affects metropolitan areas and surrounding towns as well as other aspects of the global climate.
What is a smog inspection? A smog check is an emissions test that can be done on your vehicle. It is a test that is usually performed by well trained professionals versed in car engine maintenance. It looks at how gas is emitted when the engines are in use.
The main reason why this test is done is so that the public might be protected from harmful emissions from the use of vehicles. This is an initiative that is regulated by the US government through the Environmental Protection Agency. This agency was made active in the year 1990 by the Clean Air Act. The EPA was given the authority to oversee emissions and designed the smog test to address the challenges of maintaining vehicle efficiency.
If you have ever wondered about the process that takes place during a smog check, then you are in the right place. Here are the processes that are followed when a smog check is done on your car:
- Emissions inspections: This is the stage that involves the measurement of gas emissions that include carbon monoxide, carbon dioxide and oxides of nitrogen. This can be simply put as the stage where emissions are monitored. If there is something wrong with the emissions on your car, you can find out with an emissions inspection. It’s a good idea to fix the emissions as soon as possible.
- Visual inspections and functional inspections: After you are done with the gas emissions check, the visual and functional inspections follow next. This is the part that is always so vital to proper ongoing maintenance. Sometimes when you have a problem with your car and the way it is emitting gases, the problem might be with your equipment. In some cases, it might be dysfunctional. This inspection is to ensure that the pollutants from the car’s exhaust pipes decrease to the lowest amount possible.
As technology continues to advance every day, there are more methods that are used to perform this operation. In most cases, there are a lot of methods used to carry out smog inspections. Here are the current smog check methods that may be done on your car:
- Two-Speed Idle (TSI) This test analyzes exhaust emissions from the tailpipe as the engine idles. This is a method of smog checking that has been popularized for working with older versions of cars especially that were registered in the 1990s.
- Acceleration Simulation Mode (ASM): In most cases, it is often reserved for older vehicles from before 1995. The Acceleration Simulation Mode test usually measures emissions under simulated driving conditions using an equipment called a drive-on dynamometer. It’s kind of like a treadmill for your car.
- On-Board Diagnostics (OBDI): During this test, information is usually downloaded from a car’s system that has an onboard diagnostic computer.
What happens during a Smog test?
This is a question that most people are intrigued by. If you are wondering what usually happens, here is a rundown:
- Record: For example, if you are living in the state of California, records are the measurement that are taken. The data is immediately shared and transmitted to the state agency that is responsible for smog emissions.
- Results: This is the process that comes immediately after the record is taken. You are given a copy of your results called a Vehicle Inspection Report. This is usually accompanied by a payment receipt.
- Pass or fail: This is where it is so essential to know how your car did. If you got a pass, then you are good to go, and it is legally acceptable to drive your car in your state until the next smog check. However, if it does not pass, you will be given a set of instructions on how to repair it.
Before going in for the emissions test, there are a few things you can do to improve your chances of passing. These simple strategies could make the difference between a pass and a fail.
How to pass a Smog inspection carefully (Tips to a Successful Smog Check)
1. Running right: This is the most important concept because there is just no way that you are going to be successful in the smog inspection if your car is not in the right condition. If the car is not running right on the road, there is a chance that the car will fail the test, hence losing your inspection fee. That is why it’s advisable to seek repair assistance.
2. Take a drive: Drive your vehicle for at least 20 minutes prior to arriving at the smog inspection station. This will ensure your vehicle is properly warmed up and is running at the optimum level. Remember your engine is a fuel burning machine. To ensure proper combustion it needs to have sufficient time to warm-up and this can be accomplished by driving for at least 10 to 15 miles. This should help contribute to a successful smog check.
3. Change oil: Contaminated oils are high in Hydrocarbons and will present a rich mixture to the engine chambers. Avoiding oil changes not only causes pre-mature engine wear but can also cause your vehicle to fail the smog inspection. Change the engine oil to limit these issues.
4. Use additives: The use of fuel additives can be very helpful in lowering emission levels and helping your car, truck, or van pass the emissions inspection. Fuel additives are generally poured into a vehicle's gas tank during refueling. The additive is mixed with your vehicle's fuel. The purpose is to clean carbon deposits within your engine's intake and exhaust paths, allowing for both fuel and air to flow freely within its passages, thus lowering emission levels, improving combustion, increasing overall engine performance, and helping you pass the emission test. These types of products offer helpful solutions to various vehicle emission and smog test problems.
These are just some ways to help you pass the smog inspection. By learning about your vehicle and understanding how it currently performs, you can find out the best way to maximize the performance of your car over time. There are a lot of ways to succeed with your emissions test. It is important that your vehicle has meets the minimum standards of your state to be compliant with the law. Getting a smog emissions test is a great way to do your part to facilitate a better environment.
