What Causes Car Body Shaking at High Speed?

Car body shaking during high-speed driving can be caused by several factors, including excessively high or low tire pressure, which leads to inconsistent tire energy absorption and shock absorption capabilities; severe tire wear; inaccurate wheel balancing or four-wheel alignment data; or poor fuel quality, resulting in insufficient engine power and subsequent body shaking. The specific cause requires further inspection by the car owner to address the shaking issue promptly, as it may pose safety hazards. Excessively high or low tire pressure: Significant differences in tire pressure among the four tires or severe tire wear can cause body shaking at high speeds. For example, under normal conditions, the front tire pressure is usually around 2.3 bar, and the rear tire pressure is about 2.4 bar. If the right front tire pressure is 2.0 bar and the left rear tire pressure is 2.2 bar, the inconsistency in tire energy absorption and shock absorption due to pressure differences will lead to body shaking during high-speed driving. Inaccurate wheel balancing or four-wheel alignment data: For instance, after tire repairs, rim deformation, abnormal tire wear, large nails puncturing the tire, or large stones lodged in the tread can disrupt tire balance. Additionally, significant deviations in four-wheel alignment data, especially incorrect front wheel alignment angles or excessive toe-in, can make the vehicle difficult to control during acceleration, causing shaking. Engine issues: These are generally caused by fuel quality or ignition problems. At high speeds and under heavy loads, fuel quality and ignition determine the engine's power output. If either is abnormal, it can lead to insufficient engine power and shaking.

What are the key areas to check when buying a used car?

When purchasing a used car, it is necessary to check the vehicle's documents, including the motor vehicle registration certificate, motor vehicle license, and purchase tax payment certificate; check whether the vehicle has been involved in any accidents, as used cars carry certain risks; and inspect the vehicle's condition for issues such as oil leaks and aging parts. Checking the vehicle's documents: Whether the used car's documents are complete directly affects whether the transaction and transfer can proceed. Therefore, the first step is to verify if the vehicle's documents are complete. A used car should have the following documents: motor vehicle registration certificate, motor vehicle license, and purchase tax payment certificate. Checking if the vehicle has been in an accident: When inspecting the vehicle itself, the first thing to check is whether it has been in an accident. The best way to determine if a car is an accident vehicle is to examine the weld points, especially those on the front radiator frame and chassis beams, under the door seals, on the rear trunk panel, and on both sides of the chassis. A car produced in a factory is welded by robots, so the weld points will be uniform. In contrast, an accident vehicle is manually welded by a body repair technician, resulting in uneven and irregular weld points. Checking the vehicle's condition: A car can generally be divided into four major components: the engine, body, chassis, and electrical system. Modern engines are highly computerized, and any faults will trigger error codes. Therefore, the first step is to connect a diagnostic tool to check for error codes and data streams. Common minor issues include engine oil leaks and aging rubber hoses.

Can Temporary License Plates Be Used for Inter-City Driving?

Automobile temporary license plates can be used for inter-provincial driving. The "Regulations on the Registration of Motor Vehicles" stipulate: Article 45 Under any of the following circumstances where a motor vehicle needs to be temporarily driven on the road, the owner of the motor vehicle shall apply to the vehicle management office for a temporary driving license plate: (1) The vehicle has not been sold; (2) The motor vehicle has been obtained through purchase, allocation, gift, etc., but has not yet been registered; (3) The vehicle is used for scientific research or prototype testing; (4) Special vehicles that cannot be registered due to axle load, total mass, or overall dimensions exceeding national standards. Article 46, Item 2 The vehicle management office shall, within one day from the date of acceptance, review the submitted certificates and documents. For circumstances specified in Items (1) and (2) of Article 45 of these regulations, if temporary driving within the administrative jurisdiction is required, a temporary driving license plate with a validity period not exceeding 15 days shall be issued; if temporary driving across administrative jurisdictions is required, a temporary driving license plate with a validity period not exceeding 30 days shall be issued. For circumstances specified in Items (3) and (4) of Article 45 of these regulations, a temporary driving license plate with a validity period not exceeding 90 days shall be issued. Due to reasons related to license plate production, if a license plate cannot be issued within the prescribed time limit, the vehicle management office shall issue a temporary driving license plate with a validity period not exceeding 15 days.

What materials are required for renewing an expired driver's license?

Materials required for renewing an expired driver's license include: two copies of ID card, two recent 1-inch bareheaded color photos and the original ID card, the original driver's license, and a medical examination certificate from a county-level or above hospital (free physical examinations are also available at the vehicle management office). Renewal period for driver's license: Motor vehicle drivers should apply for renewal at the vehicle management office of the driver's license issuing authority within 90 days before the expiration of the motor vehicle driver's license. When applying, the "Motor Vehicle Driver's License Application Form" should be filled out. Penalties for expired driver's license: Driving a motor vehicle is not allowed during the expiration period, otherwise it may be treated as driving without a license. If the driver's license has been expired for less than one year, the driver can renew it at any time, but if driving on the road, a fine of 200 yuan will be imposed. If the driver's license has been expired for more than one year without renewal, the traffic management department will cancel it according to the law. Among them, if the expiration period is less than three years, the driver must retake and pass the subject one exam to restore the driving qualification. Driving on the road during this period will face a fine of 200 to 2000 yuan. If the driver's license has been expired for more than three years, the driver's license will be completely canceled, and the driver must retake the driver's license test to drive again. Otherwise, driving on the road will be treated as driving without a license, with a fine of 2000 yuan and administrative detention for up to 15 days.

How to Charge an ETC Battery?

ETC devices can be charged via solar panels or wired charging. ETC devices with solar panels do not require charging, while those with wired charging need to be charged using a charger. Both types of ETC electronic tags have internal batteries. Solar-powered ETC devices do not require charging during daily driving, and their lithium batteries typically last 3 years under normal use. However, for those who do not frequently use ETC, it is recommended to charge the ETC device every 3 months to effectively mitigate the impact of natural battery discharge on its lifespan. ETC stands for Electronic Toll Collection, which is an electronic toll system. To apply for ETC, the vehicle owner must provide original and photocopied versions of their valid ID card and vehicle registration certificate. If someone else is handling the application on behalf of the owner, they must also bring their own valid ID card. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway toll fees is required. Applicants must be between 18 and 60 years old, and the vehicle must be registered under their name. How ETC works: The onboard electronic tag, installed on the vehicle's windshield, communicates with the microwave antenna in the ETC lane at toll stations. Using computer networking technology, it settles payments with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions, as vehicles pass through toll stations without stopping; Cost-saving: Reduces wear and tear, lowers fuel consumption, and users can enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
