What are the reactions of a car when the battery is dead?

When the car battery is dead, the car will exhibit the following reactions: 1. Abnormal vehicle starting: Normally, the vehicle starts successfully with one attempt, but when the battery has issues or is low on power, it may require multiple attempts to start the vehicle, or it may not start at all. Additionally, there may be a "squeaking" noise. 2. Headlights dimming at idle: While driving, the headlights function normally, but when the vehicle is idling, the headlights become less bright. This happens because the engine's charging power decreases at idle, and if the battery is faulty, it cannot supply the required power for the headlights, making them dimmer when parked compared to when driving. 3. Battery warning light on: The battery warning light indicates that the battery needs replacement. When this light comes on, it is advisable to visit a repair shop for battery inspection and maintenance.

Should I go to a 4S shop or a repair shop for a dent in my new car?

New cars usually have full insurance coverage. Since you can claim insurance, it is recommended to go to a 4S shop. Here is some relevant information: 1. Reasons to go to a 4S shop: If it's a minor accident for a new car, it's fine, but if it's a serious accident that damages the chassis or transmission, neither the 4S shop nor the repair shop can easily handle it. The 4S shop might subcontract such repairs to more professional technicians. Professional repair shops might do the same, but smaller ones might try to fix it themselves for profit, which is definitely less reliable. New cars usually have full insurance coverage, so it's better to go to a 4S shop if you can claim insurance. 2. Benefits of repair shops: 4S shops, especially those of mainstream brands in good locations, are often overcrowded on weekends or after work hours. If your car needs repairs after an accident, waiting for service and wanting to drive away immediately is often unsatisfactory. However, repair shops are different. To attract customers, if you are in a hurry to get your car back, the repair shop will definitely work overtime to fix it for you.

What Causes Severe Vibration When Braking a Car?

Severe vibration when braking a car can be caused by: 1. Tire deformation; 2. Improper tire dynamic balance; 3. Vehicle drivetrain malfunction; 4. Worn or loose ball joints or detached rubber bushings at connections; 5. Twisted or deformed drive shaft; 6. Uneven brake discs; 7. Overly loose or tight power steering belt. The brake is a mechanical braking device that slows down the vehicle, also known as a decelerator. The car's brake pedal is located below the steering wheel. Pressing the brake pedal activates the brake linkage, transmitting pressure to the brake shoes on the brake drum, which then clamp the brake rotor to decelerate or stop the vehicle. Brake maintenance tasks include: 1. High-temperature protection for brake pads; 2. Lubrication maintenance for brake calipers; 3. Cleaning of brake discs; 4. Replacement of brake fluid; 5. Rust prevention and lubrication for wheel bolts, brake discs, and contact surfaces with rims.

Is an ignition advance angle of 12 degrees or 9 degrees better?

An ignition advance angle of 9 degrees is better for the following reasons: The ignition advance angle is generally between 6 and 12 degrees. A 12-degree ignition advance angle is too large compared to 9 degrees, which can lead to delayed ignition. If ignition is delayed, the gas will have difficulty performing work, fuel consumption will increase, efficiency will decrease, and exhaust noise will become louder, affecting the engine's operational efficiency. Below is a related introduction to the ignition system: 1. Function: In a gasoline engine, when compression nears the top dead center, the combustible mixture is ignited by the spark plug, thereby burning and performing external work. For this reason, gasoline engine combustion chambers are equipped with spark plugs. The function of the ignition system is to generate a sufficiently energetic spark between the electrodes of the spark plug in the correct sequence according to the cylinder's working order. 2. Requirements: The voltage required to produce a spark when the spark plug electrodes break down is called the breakdown voltage. The secondary voltage generated by the ignition system must be higher than the breakdown voltage to ensure the spark plug fires. The magnitude of the breakdown voltage is influenced by many factors, including: (1) Spark plug electrode gap and shape: The larger the gap between the spark plug electrodes, the higher the breakdown voltage; electrodes with sharp edges require a lower breakdown voltage. (2) Pressure and temperature of the mixed gas in the cylinder: The higher the pressure and the lower the temperature of the mixed gas, the higher the breakdown voltage. (3) Temperature of the electrodes: The higher the temperature of the spark plug electrodes, the lower the gas density around the electrodes, resulting in a lower breakdown voltage.

How long does it take to check vehicle records after running a red light violation?

After running a red light, the violation record can usually be checked within 3 to 7 days, with a maximum of around 13 days. However, some cities now offer an "electronic police instant notification" service, where you may receive an SMS notification within 5-10 minutes after being captured. However, this notification does not confirm the violation; it only serves as a capture alert. The final determination of whether a violation occurred will take 3-7 days. If a violation is confirmed, you will receive another SMS notification. For violations captured by surveillance cameras, vehicle owners generally do not receive an immediate violation notification via SMS. There is usually a delay, and the duration may vary. This is because after the electronic camera captures the violation, the relevant violation information needs to be transmitted through a dedicated channel to the traffic police management center. The information is then compiled and forwarded to the relevant traffic police personnel for verification. Once the violation is confirmed, the system will automatically retrieve the vehicle owner's phone number based on the license plate information. The violation details will then be sent to the owner via SMS. After receiving the violation SMS, the vehicle owner must settle all outstanding violations within one month before the vehicle's annual inspection. Generally, if a vehicle owner suspects a violation, they can use 15 days as a benchmark. If no violation SMS is received within 15 days, it is likely that no violation was recorded. Methods for traffic violation inquiries: Traffic violation inquiries refer to checking motor vehicle violations of traffic regulations through online platforms, inquiry terminals, etc. Methods for vehicle violation inquiries include website inquiries, phone inquiries, SMS inquiries, mobile app inquiries, and offline terminal inquiries. Website inquiry: You can search for "vehicle violation inquiry" and enter your vehicle information to check. Phone inquiry: You can call the local 114 (area code + 114) or 12580 to confirm traffic violations. Violations can only be processed at the location where the violation occurred or where the vehicle's license plate was issued. For on-the-spot violations, such as those directly caught by traffic police, they must be processed at the violation location. SMS inquiry: Open your phone's SMS composition interface; enter "WZ" followed by your license plate number and color in the message body; enter 1062650001 as the recipient and click send. Mobile app inquiry: Open the Traffic Management 12123 app, log in, and click on "Vehicle Violations" to access the inquiry interface. The displayed results will show recent unprocessed violation records. Offline terminal inquiry: Visit the local traffic management office and use the self-service inquiry machine to enter your license plate number and check recent violation records.

Can a China V vehicle be transferred to another region?

Local China V vehicles can be transferred normally, but inter-provincial transfers of China V vehicles generally cannot be processed locally. Specific details should be confirmed with the local vehicle management office of the destination. Here is some relevant information: 1. Introduction to China V Standard: The China V Standard, officially known as the National Fifth Stage Motor Vehicle Pollutant Emission Standard, is abbreviated as "China V Standard." Its emission control level is equivalent to the European Euro 5 emission standard, though Europe began implementing the Euro 6 standard as early as 2013. The China V Standard applies to vehicles with a maximum total mass of less than 3.5 tons. Compared to China IV, the China V Standard reduces nitrogen oxide (NOx) emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles, making the emission standards stricter. 2. Restrictions on New China V Vehicle Registrations: Even with the implementation of the China VI emission standard, China V vehicles can still be transferred locally without immediate impact. The China VI standard primarily restricts the registration of new China V vehicles, targeting newly manufactured cars. However, used China V vehicles in the second-hand car market are not restricted from registration, as used car transactions only involve transfer procedures and do not require re-registration. As long as the necessary documents—such as the property certificate, vehicle license, valid inspection certificate, compulsory insurance, and the owner's ID—are complete, the used car transaction can proceed. The China VI and China V emission standards have no impact on used car transactions.
