How to Pass the Exhaust Emission Test During Annual Inspection?
1 Answers
Exhaust emission testing is a mandatory item during the annual inspection of vehicles. To pass the exhaust emission test during the annual inspection, regular maintenance of the three-way catalytic converter is essential. Use cleaning solvents, drip cleaning, or non-disassembly cleaning methods for the three-way catalytic converter. Some 4S shops offer this service. Before the test, try to use up the fuel in the tank and then refill with higher-grade fuel from a reputable gas station, as this can help with the emission test. If the vehicle has been used for a long time and shows signs of corrosion in the exhaust pipe, it is advisable to have it inspected and repaired promptly. If necessary, replace the exhaust pipe to improve the chances of passing the emission test. Severely corroded exhaust pipes usually make it difficult to pass the test. Nowadays, when purchasing vehicle insurance, insurance companies often provide inspection cards that assist with the annual inspection and exhaust emission testing, saving a lot of hassle. Dedicated channels can also help ensure a smooth emission test. Be sure to check with the insurance company if they assist with the emission test. Many vehicle owners lack confidence in their vehicle's condition and may attempt to pay someone to 'help' pass the emission test.
