What is the emission standard for the 2013 Jetta?

The 2013 FAW-Volkswagen Jetta models sold in regions outside of Beijing, Shanghai, and Guangzhou generally comply with the China IV emission standard, while some models sold in these major cities meet the China V standard. Additional relevant information is as follows: 1. Automobile emission standards regulate the permissible levels of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). Starting from January 1, 2004, Beijing upgraded its vehicle emission standards from Euro I to Euro II, and by 2008, it officially implemented the Euro III standard. 2. Automobile emissions refer to the harmful gases released from exhaust, such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). These gases are byproducts of engine combustion. The reasons for their production vary: CO is an intermediate product of incomplete fuel oxidation, occurring when oxygen is insufficient; rich or uneven air-fuel mixtures increase CO emissions. HC consists of unburned fuel components, resulting from uneven mixtures or cold combustion chamber walls causing incomplete combustion. NOx is produced during the combustion of fuel (gasoline). PM forms when fuel burns under oxygen-deficient conditions, particularly noticeable in diesel engines due to their compression-ignition process, where diesel fuel decomposes under high temperature and pressure, generating visible soot particles.

How Often Should You Start a Car That's Not Driven for Long Periods?

It is recommended to start a car that is not driven for long periods approximately every 15 days. Here are some precautions for long-term vehicle storage: 1. The most common issue with long-term vehicle storage is the battery. Even when the car is parked and locked, certain components like the anti-theft system still require power, resulting in a small but continuous drain on the battery. Over time, this can lead to a low battery charge, making it difficult to start the engine. 2. To prevent the battery from losing too much charge, it is important to periodically start the engine and let it run for at least 30 minutes to recharge the battery. This is especially necessary if the car has been parked for more than 15 days. 3. Long-term parking can also cause the tires to develop flat spots from remaining in the same position for extended periods. This may lead to tire deformation and vibrations when driving. To avoid this, the vehicle should be moved periodically to distribute the weight more evenly across the tires.

How often should the spark plugs of an Audi Q5 be replaced?

Audi Q5 spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable to follow the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. How spark plugs work: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it ionizes the medium between the central electrode and the ground electrode to produce a spark, thereby igniting the air-fuel mixture in the cylinder.
