There are many reasons why a vehicle may fail the environmental inspection, primarily due to excessive levels of CO, HC, NO, etc. Below is relevant information about vehicle inspections: 1. Definition: Vehicle inspection, also known as annual inspection, is conducted by the traffic police department to assess the annual performance and condition of a vehicle. New vehicles are inspected every two years. 2. Exemption Policy: The Municipal Traffic Police Corps reminds that the so-called exemption only refers to waiving the on-site inspection. Vehicle owners still need to undergo a regular inspection every 2 years. After providing proof of compulsory traffic accident liability insurance, payment or exemption of vehicle and vessel tax, and resolving any traffic violations or accidents, they can directly apply to the traffic management department for the inspection label. However, if the vehicle is involved in a traffic accident causing casualties during the exemption period, the original inspection requirements will be reinstated.

I just dealt with this headache last week. After a mechanic's inspection, it turned out the catalytic converter was clogged, causing severe exhaust emissions. They suggested first removing it and soaking it with specialized cleaner, which cost over 300 yuan, but it still failed the inspection. Eventually, replacing the catalytic converter solved the problem, costing nearly 2,000 yuan in total. I recommend avoiding gas from small gas stations and regularly driving on highways to clear carbon buildup—it saves a lot of hassle before annual inspections. If cleaning doesn't work, just replace the converter. After all, cars over ten years old rarely escape this issue.

Is Tire Sealant Harmful to Car Tires?

Automotive tire sealant can cause some damage to tires. After using tire sealant, the tire surface will inevitably suffer some degree of corrosion. Additionally, the adhesive protective film formed on the tire surface can interfere with the grinding and bonding processes during subsequent tire repairs, making future repairs more difficult and potentially even impossible. The design principle of automatic tire sealant is as follows: a liquid containing certain short fibers or fine particles is pre-injected into the tire in a specific quantity. If the tire has tiny holes, they will be plugged. When a puncture occurs, the escaping air carries the liquid with fibers or particles out, which are then squeezed into the puncture, instantly and tightly sealing it. This prevents further air leakage, maintains sufficient tire pressure, allows the vehicle to continue driving, and prevents potential accidents.

How to Turn on the External Air Circulation?

Method to turn on the external air circulation: Locate the button with a car symbol in the air conditioning control area. The button with an arrow pointing from outside the car into the car is the one for turning on the external air circulation. Press this button to activate the external air circulation. Some cars do not have an external air circulation button, only an internal air circulation button. Usually, when the light on the internal air circulation button is on, it means the internal air circulation is active. Pressing it again to turn off the light switches to the external air circulation mode. The external air circulation is suitable for use when it is inconvenient to open windows for ventilation, such as during high-speed driving. The external air circulation can replenish fresh air and also help defog the windshield on rainy days.

What are the repair methods for a generator not generating electricity?

Generator not generating electricity repair methods are: 1. If the generator belt is broken or slipping, tighten the adjustment device or replace the belt; 2. Check for open circuits in the generator output wires and inspect wire condition; 3. If the rotor part is stuck, manually test whether it rotates smoothly; 4. If the winding is damaged, use a multimeter to measure the coil resistance to see if it is normal. If there is no resistance value, the coil must be rewound or the motor replaced. The car generator is the main power source of the vehicle. Its function is to supply power to all electrical devices (except the starter) when the engine is running normally (above idle speed), while also charging the battery.

What is the Principle of Wet Dual Clutch?

The principle of wet dual clutch is: The torque transmission of a wet dual clutch is achieved through the friction plates submerged in oil. Since the friction plates of a wet dual clutch transmission are immersed in transmission oil, the oil can provide cooling and lubrication, allowing it to withstand greater loads. A wet clutch utilizes hydraulic pressure for engagement, controlling the transmission of driving force during both the separation and full engagement of the clutch, including situations with relative rotation. Unlike dry clutches, wet clutches primarily rely on hydraulic operation and are generally used in automatic transmissions and continuously variable transmissions (CVTs) that require higher smoothness.
