The difference between Y and W tires lies in their speed ratings: Y-rated tires have a speed rating of 300 kilometers per hour, while W-rated tires have a speed rating of 270 kilometers per hour. The main functions of tires are: 1. To support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; 2. To transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface, thereby improving the car's power, braking, and off-road performance; 3. To work together with the car's suspension to cushion the impact during driving and dampen the resulting vibrations; 4. To prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and fuel efficiency.

How Long Does It Take to Receive a Text Notification After Running a Red Light?

Generally, you can receive a text notification within 3 to 7 days after running a red light. If you haven't received a text after 7 days, you can wait a bit longer, as it takes time to collect, organize, verify, and upload the violation data from the time the infraction occurs. Usually, the notification won't take longer than 15 days. If you haven't received a text after 15 days, it means there is no violation record. Criteria for determining a red-light violation: According to Article 51 of the "Regulations for the Implementation of the Road Traffic Safety Law": When a motor vehicle passes through an intersection controlled by traffic signals, it shall comply with the following rules: (5) Upon encountering a stop signal, the vehicle must stop outside the intersection. A vehicle is only considered to have run a red light if it crosses the stop line while the light is red and proceeds through the entire intersection. There are usually detection lines (with induction coils) before and after the crosswalk to sense whether a vehicle crosses the line during a red light, followed by photographic evidence. Three photos are taken as evidence: the front wheels crossing the detection line, the rear wheels crossing the detection line, and the vehicle crossing the detection line on the opposite side of the intersection. Maintain a safe braking distance; failure to do so may result in electronic enforcement. Always follow traffic rules. For violations captured by surveillance cameras, vehicle owners typically do not receive an immediate notification. There is usually a delay, which can vary in length. After an electronic camera records a violation, the relevant information is transmitted through a dedicated channel to the traffic police management center, where it is compiled and reviewed by staff. If confirmed as a violation, the system automatically retrieves the vehicle owner's phone number based on the license plate information and sends a text notification. After receiving a violation notification, the vehicle owner must visit the local traffic police department to address the issue at least one month before the vehicle's annual inspection. If you suspect a violation but haven't received a notification within 15 days, it likely means no violation was recorded. Methods for checking traffic violations: Traffic violation checks refer to querying motor vehicle violations of traffic regulations via online platforms, hotlines, text messages, or mobile apps. Online query: Search for "vehicle violation check" and enter your vehicle details. Phone query: Dial local 114 (area code + 114) or 12580 to confirm violations. Violations can only be processed at the location of the infraction or the vehicle's registration jurisdiction. For on-the-spot violations (e.g., being stopped by an officer), they must be handled at the violation site. Text message query: Open your phone's messaging app, enter your license plate number in the message body, and send it to 1062650001. Mobile app query: Open the "Traffic Management 12123" app, select "Violation Query," and resolve any outstanding violations.

What Causes Car Steering Wheel to Pull to One Side?

Car steering wheel pulling to one side can be caused by the following reasons:1. Uneven tire pressure.2. Different tire tread patterns or uneven tread depth.3. Deformation of front shock absorber springs.4. Failure of front shock absorbers.5. Body deformation.6. Excessive wear of chassis components.7. Incorrect four-wheel alignment.8. Brake system malfunction. Below are the related methods for adjusting steering wheel misalignment:(1) If the vehicle pulls to the left, slightly adjust the steering to the right; if it pulls to the right, slightly adjust to the left.(2) Rotate or replace the tires.(3) Replace suspension springs.

Are There Benefits to Applying Film on Car Windshields?

Applying film on car windshields has benefits. The advantages of windshield film are as follows: 1. Sun protection: Blocks UV rays. The windshield has a large surface area exposed to heat and receives the most UV radiation. Applying film can effectively block UV rays, protecting the health of the driver and passengers. 2. Heat insulation: The film on the front windshield can block some heat. 3. Anti-glare: During the day, bright sunlight can cause glare, and at night, the strong lights from oncoming vehicles can also produce dazzling glare, especially when driving on rainy nights when the lights are more chaotic. The windshield film can effectively reduce this glaring light. 4. Anti-shatter function: This is one of the main reasons car owners apply film. Since the front windshield is made of tempered safety glass, if the glass shatters, the film prevents the fragments from flying, thereby protecting the driver's safety.

How to Adjust Valves on a Four-Cylinder Engine?

Here are the methods for adjusting valves on a four-cylinder engine: 1. Cylinder-by-Cylinder Adjustment Method: According to the firing order of the cylinders, determine when a piston is at the top dead center of the compression stroke, then adjust the intake and exhaust valve clearances for that cylinder. After adjustment, rotate the crankshaft and proceed to adjust the valve clearances of the other cylinders step by step using this method. 2. There are four models: L3, L4, L5, and L6. The advantages of this engine layout include compact size, high stability, good low-speed torque characteristics, and lower fuel consumption, which means lower manufacturing costs. 3. Engines with an inline cylinder layout are relatively compact in size, allowing for more flexible arrangements. They are also convenient for installing superchargers and similar devices. The main disadvantage is that the engine's power output is relatively low, making it unsuitable for models with more than six cylinders.

What Could Be the Problem If the Compressor Is Very Noisy?

Here are the possible issues when the compressor has abnormal noise: 1. Abnormal noise from the compressor electromagnetic clutch: The installation position of the electromagnetic clutch is generally close to the ground and often comes into contact with rainwater and mud. When the bearing of the electromagnetic clutch is damaged, it will produce abnormal noise. 2. Abnormal noise caused by the tightness of the compressor drive belt: If the drive belt is too loose, the electromagnetic clutch is prone to slipping; if the drive belt is too tight, the load on the electromagnetic clutch will increase. Here are some related precautions for compressor maintenance: 1. Do not handle refrigerant in an enclosed space or near an open flame. 2. Avoid liquid refrigerant entering the eyes or splashing on the skin. 3. Do not place the refrigerant can directly in hot water with a temperature higher than 40 degrees Celsius.

Can Auto Hold and Auto Start-Stop Be Used Together?

Auto Hold and Auto Start-Stop can be used together, and when utilized properly, these two features can help save fuel. Here is more information about Auto Hold and Auto Start-Stop: 1. Auto Start-Stop: This function temporarily stops the engine when the vehicle comes to a halt during driving, such as when waiting at a traffic light. While driving, simply press the brake pedal fully, and after about two seconds of complete stop, the engine will automatically shut off. Keeping the brake pedal pressed will maintain the engine in the off state. As soon as you release the brake or turn the steering wheel, the engine will automatically restart, allowing you to press the accelerator and start moving immediately—all while remaining in D gear. 2. Auto Hold: The Auto Hold system is a feature that automatically applies the handbrake for you. This function is particularly useful on slopes and during frequent stops and starts.
