The Difference Between W and Y Tires

Tire y and w difference: 1. Tires are composed of inner tubes and outer tires. 2. Tires are generally measured in sets. Tires are one of the most important components of a car. 3. They are typically not used in household cars but mainly in luxury cars and sports cars. 4. The speed rating for W is 270 km/h, while for Y it is 300 km/h. Under China's speed limit conditions, the difference between these two speed-rated tires is not significant. Their main functions include: 1. Supporting the entire weight of the vehicle, bearing the car's load, and transmitting forces and moments in other directions. 2. Transmitting traction and braking torque to ensure good adhesion between the wheels and the road, improving the car's power, braking, and passability. Together with the car suspension, they mitigate the impact during driving and dampen the resulting vibrations. 3. Preventing severe vibrations and early damage to car components, adapting to the vehicle's high-speed performance, and reducing driving noise. 4. Ensuring driving safety, handling stability, comfort, and energy efficiency.

How to Schedule Subject 4?

You can ask the driving school to help you schedule it, or you can download the Traffic Management 12123 APP and schedule it yourself. Here is some relevant information: 1. About Subject 4: Subject 4 is now the civility and common sense test of Subject 3. Subject 4, also known as the theoretical test for drivers, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: the road test and the safety and civility common sense test, commonly referred to as 'Subject 4,' which assesses 'driving ethics.' Since this test is conducted after Subject 3, it is commonly referred to as Subject 4. Officially, there is no Subject 4. 2. About the test: The exam consists of 50 questions, presented in the form of case studies, images, animations, etc., with a full score of 100 and a passing score of 90. Subject 4 extracts the requirements for safe and civilized driving, safe driving skills under complex conditions, and emergency handling knowledge from the original Subject 1 and places them after the actual road driving test of 'Subject 3' to further assess the candidate's level of traffic awareness.

Why Can't I Bind the Registered Vehicle?

Registered vehicles may not be bound due to discrepancies between the original registration information and your current situation, such as a mismatch in mobile phone numbers (e.g., the number provided at the time of purchase differs from your current one). Please carefully review the reasons and attempt to rebind. Below is relevant information about registered vehicles: 1. Conditions for registering a vehicle: (1) Only personal vehicles can be registered, and the vehicle must be a small car or a small new energy vehicle. (2) A user can register no more than 3 non-personal vehicles (inclusive). 2. Notes: (1) A driver can simultaneously register up to any 3 non-personal small cars. A single small car can be registered by no more than 3 drivers other than the owner. Drivers can deregister and re-register other non-personal small cars at any time, as long as the total does not exceed 3. (2) For non-personal vehicles, only electronic monitoring violations of small cars and small new energy vehicles can be processed independently.

How to Deal with Mold in the Car?

Here are the methods to handle mold growth in the car: 1. Evaporate the moisture: Mold growth in the car is mainly due to prolonged lack of ventilation and excessive humidity, which fosters mold. Turn on the car's air conditioning at the highest temperature setting and let it blow for a while to evaporate the moisture in the air conditioning ducts, preventing mold growth inside the car. 2. Sun exposure: Open the car doors and windows and park in a sunny area for several hours. Mold is highly sensitive to high temperatures and direct sunlight. The unfavorable environment will quickly eliminate the mold. 3. Place activated bamboo charcoal in the car: Besides absorbing moisture, formaldehyde, sulfides, and other harmful substances, activated bamboo charcoal can also deodorize and regulate humidity. After initial treatment, placing some activated bamboo charcoal in the car can purify the air and prevent mold from recurring. 4. Photocatalytic catalyst: There is now a photocatalytic catalyst that effectively sterilizes and purifies the air. The application is very simple—spray the catalyst inside the car. When exposed to sunlight, the photocatalyst activates, quickly sterilizing and absorbing harmful substances. 5. Solar-powered air purifier: You can place a car air purifier inside the vehicle to absorb dust and particulate matter in the air, decompose harmful substances, purify the air, and remove dust and bacteria. However, these purifiers tend to be more expensive.

What are the new driving license regulations in 2020?

The new driving license regulations in 2020 are as follows: 1. Implement nationwide 'one-certificate examination' for small car driving licenses: Applicants can apply for a small car driving license anywhere in the country with their resident ID card, without submitting a residence registration certificate. Residents from Hong Kong, Macao, and Taiwan can apply with their residence permits for Hong Kong, Macao, and Taiwan residents. 2. Implement inter-provincial subject tests for small car driving licenses: If an applicant who is applying for a small car driving license has passed some subjects but needs to change their residence due to work, study, or life reasons, they can apply once nationwide to change the test location. The applicant can present their ID card to the local vehicle management office to continue taking other subject tests, and the passed subject test results remain valid. 3. Pilot the inter-provincial application for large and medium-sized passenger and truck driving licenses within the province: Applicants applying for large and medium-sized passenger and truck driving licenses within the province can apply directly with their resident ID card without submitting a residence registration certificate. For inter-provincial applications, after obtaining a residence permit in any location of the current province, they can also directly apply for large and medium-sized passenger and truck driving licenses within the province.

What to Do When the Engine Warning Light Comes On in a Volkswagen Sagitar?

If the engine warning light comes on, follow these steps: First, check whether the engine is running normally and if there are issues such as shaking or emitting black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The car will perform a self-check after powering on. Wait for 5-10 seconds and observe whether the warning light on the dashboard turns off. If the warning light remains on, visit a service center as soon as possible to diagnose the issue. The service center can use a portable diagnostic tool to read the fault code, identify the problem, and perform targeted repairs. There are seven main reasons why the engine warning light may come on: 1. Sensor failure: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may become damaged, have poor contact, or experience signal interruption. When the car's ECU cannot accurately obtain engine data, the engine warning light will illuminate. 2. Fuel or oil quality issues: Using fuel or oil that does not meet the manufacturer's specifications may cause engine wear, leading to the warning light turning on. 3. Poor combustion of the air-fuel mixture: Poor combustion can cause engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can lead to poor combustion. 4. Turbocharger problems: Issues with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common issue is a damaged turbocharger, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. 5. Intake problems: If the car's intake system is compromised, it may lead to clogged engine pipes, and in severe cases, the engine warning light will come on. A dirty or uncleaned air filter can cause intake issues. 6. Exhaust problems: Exhaust system faults can also trigger the engine warning light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequent culprit. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system issues can all lead to catalytic converter failure. 7. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine ECU, the anti-theft system may prevent the engine from operating normally, and the engine warning light will illuminate.
