A probe is placed in the tailpipe of the car and the exhaust gases are measured following a strict procedure. The exhaust gas analyser is used for measuring 4 gases, oxygen (O2), carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbons (HC) as well as calculating lambda (λ) a measure of air/fuel ratio.
Clean the entire fuel system: pre, during, and post-combustion to effectively reduce vehicle emissions with Pre-Emission Test Treatment, which is designed to reduce exhaust emissions to help pass an emission test.
How do you measure car emissions?
Carbon dioxide emissions are measured by weight, in grammes (g) and calculated by how much CO2 is emitted from the exhaust pipe per the distance driven, measured in kilometres (km). CO2 emission rates are usually displayed as (g/km).
Adding a cleaning agent into the fuel system will help remove the deposits and lower the emissions.
The exhaust and fuel cleaner should be used every three months to maintain optimum efficiency.
Use better fuel.
Change the oil.
Change the air filter.
Check your tyre pressure.
How do I check my exhaust emissions? – Related Questions
What causes car emissions to be high?
The main culprit? A faulty exhaust. Usually, your exhaust and catalytic converter work together to limit the amount of harmful gasses your engine produces. However, when your exhaust is old, worn or damaged, it’s much less effective at doing so.
What causes a car to fail on emissions?
This may happen if the vehicle has not been maintained properly or has been sitting idle for a long period of time. Other reasons for a failed emissions test include a damaged catalytic converter, faulty oxygen sensor, rich air-fuel mixture or a vacuum system leak.
Can I drive with exhaust emission warning light on?
So, is it safe to drive with the Emissions Control Light on? Yes, as long as it is the only light that has come on, you do not have to worry about your safety. However, you should still find out what is causing the problem, and then have it fixed.
How much does it cost to fix emissions UK?
For most modern cars, you should be expecting a figure anywhere in the region of £150 to £800. Remember, franchise and dealership costs will feature at the top end of the scale whatever your car, so shop around, and always choose a reputable and trustworthy mechanic to carry out the work.
Change Your Oil and Oil Filter Regularly. Oil helps to lubricate your vehicle, keeping its parts clean, prevent overheating, and minimize excess wear due to friction.
Change Your Fuel Filter Regularly.
Change Your Air Filter Regularly.
Change Your PCV Valve Regularly.

Does driving slower reduce emissions?
Vehicles travelling at lower average speeds do not always emit more pollutants because average speeds mask fast and slow periods. Engines are optimally efficient when driving at a constant (‘cruising’) speed, not when accelerating or decelerating. For most cars, this is around 55-60mph.
Why do I smell exhaust fumes when I start my car?
This is most commonly caused by things like leaking fuel injectors, a clogged engine air filter, a bad mass airflow sensor, bad throttle body or bad oxygen sensor.
Do mufflers reduce emissions?
Your exhaust manifold, down pipe, A pipe, B pipe, and muffler have nothing to do with reducing emissions. They’re all about getting gases away from the engine without exposing you and your passengers to them. The muffler’s only job is to dampen the sound of your exhaust.
What part of a car reduces emissions?
Catalytic Converters. A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants in exhaust gas from motor vehicle engines into less-toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction).
How much does it cost to fix an emission control system?
If your vehicle failed emission testing and it needs repairing, then the cost will depend on the exact cause, but the repair work typically starts around $200. Replacing your exhaust system depends on the type of car you drive, but that work starts at approximately $175.
How do you tell the difference between a muffler and a catalytic converter?
Differences Between Mufflers and Catalytic Converters
Mufflers are designed to dampen the noise of exhaust systems by reducing the pressure of exhaust gases. Catalytic converters, on the other hand, are designed to convert harmful byproduct gases into less-harmful byproduct gases via a catalyst.
How do you check a catalytic converter?
What does a resonator delete do?
Resonator delete helps optimize the frequencies of the pulses generated by your car, thereby achieving a certain level of improved power production. It could make your car’s exhaust sound loud and aggressive. However, it helps in maintaining optimum fuel mileage, high performance, and efficiency.
Can you put a muffler in place of a catalytic converter?
The short answer is yes you can.
This is because a catalytic converter’s primary job is to convert dangerous emissions (like carbon monoxide) from gasoline-fueled engines into more environmental-friendly gases, like carbon dioxide or water vapor.
Can you drill holes in a catalytic converter to unclog it?
Drilling holes on a catalytic converter is never a good idea. By doing so – you allow toxic gases to leak out. At best, this will pollute the environment. At worst, these toxic gases could enter your car and poison you.
