What Causes Tire Cracking?

Will points be deducted if the driver's license expires?

An expired driver's license cannot be used for point deduction. Here are the solutions for an expired driver's license: 1. Required documents for renewal: Original and photocopy of ID card, original driver's license, 3 recent 1-inch color photos with white background, application form for motor vehicle driver's license. Medical examination certificate (issued by a medical institution at or above the county level or military regiment level or the vehicle management office's medical examination point). If you are not a local resident, you also need to provide the original and photocopy of the local residence permit. 2. Consequences: If you keep delaying, and the driver's license expires for more than three years or longer, the driver's license will be forcibly canceled. At this time, you can only register for a driving school again and retake the test to obtain a driver's license.

What do the numbers on the front windshield mean?

In fact, the 17-digit number on the car windshield is the vehicle's VIN (Vehicle Identification Number). The VIN, also known as the chassis number, is a unique 17-character alphanumeric code that serves as the car's ID card. Each vehicle has its own unique VIN. The letters and numbers in the VIN represent information such as the vehicle's production region, manufacturer, production year, and model. Here is some extended information: 1. The VIN can be found in the following three locations: (1) On the front partition of the engine compartment. (2) On the driver's side of the windshield. (3) On the vehicle's central pillar nameplate. Additionally, a professional diagnostic tool can read the electronic VIN and vehicle status information. 2. Interpretation of the VIN: (1) Positions 1-3 (WMI): World Manufacturer Identifier. The first digit represents the country or region of production, and digits 2-3 indicate the manufacturer and vehicle type. (2) Positions 4-9 (VDS): Vehicle Descriptor Section. Digits 4-8 represent the vehicle's type, series, body, and engine type, among other details. The 9th digit is a check digit. (3) Positions 10-17 (VIS): Vehicle Identifier Section. The 10th digit indicates the production year. The 11th digit is the assembly plant code. Digits 12-17 represent the vehicle's production sequence number.

What are the engine specifications of Changan Oushang?

Different models of Changan Oushang have different engines. The 2022 1.5T and 2021 1.5T Changan Oushang X5 use the JL473ZQ2 engine model, with a maximum horsepower of 180 hp, maximum power of 132 kW, maximum power speed of 5500 rpm, and peak torque of 300 N.m. The 2021 1.6T Changan Oushang X5 uses the JL478QEP engine model, with a maximum horsepower of 128 hp, maximum power of 94 kW, maximum power speed of 6000 rpm, and peak torque of 161 N.m. The 1.5T and 1.6T engines of Changan Oushang are domestically produced, independently manufactured by Changan Company, with the factory located in Chongqing. For daily maintenance of Changan Oushang engines, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, select CB_CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid faults, change the oil regularly according to usage conditions and keep the oil volume moderate; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, it will burst the filter element or open the safety valve, passing through the bypass valve and bringing dirt back to the lubrication area, accelerating engine wear and internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and cylinder wall, mixing with metal powder produced by part wear to form sludge. When the amount is small, it suspends in the oil; when the amount is large, it precipitates from the oil, blocking the filter and oil holes, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.

Can a Manual Transmission Converted to Automatic Pass the Annual Inspection?

Converting a manual transmission to an automatic one will not pass the annual inspection. Below are the relevant regulations regarding modifications: 1. Legal Provisions: The new "Road Traffic Safety Law" explicitly states that no unit or individual may assemble a motor vehicle or alter its registered structure, construction, or characteristics without authorization. The structure of a vehicle includes the body color, length, width, height (four rigid standards), and the relevant technical parameters of the engine. 2. Registration and Declaration: Before modifying a licensed vehicle, the owner must register and declare the modification to the vehicle management office. The modification can only proceed after the technical report is reviewed and approved by the office. After the modification is completed, the owner must also complete the modification change procedures at the vehicle management office. 3. Photo Consistency: The legality of vehicle modifications depends on whether the vehicle matches the photo on the driving license and whether it complies with the factory technical parameters. If not, the vehicle will not pass the annual inspection.

What are the consequences of a damaged CV joint?

When the outer CV joint is damaged and not repaired, it will make a clicking noise during turns, and in severe cases, the CV joint may detach, leading to loss of steering control. Below is relevant information about CV joints: 1. Function: Transmits the engine's power from the transmission to the two front wheels, enabling the car to drive at high speeds. The dust cover is a critical component of the CV joint, primarily preventing dust from entering the joint and stopping the grease inside from leaking out. Special high-temperature resistant grease must be used in CV joints; other lubricants cannot substitute. 2. Classification: One type is the fixed ball-type CV joint (RF joint), characterized by transmitting torque while allowing only relative rotation between the driving and driven shafts without axial displacement, typically used near the wheels, commonly referred to as the outer CV joint. The other type is the sliding ball-type CV joint (VL joint), which not only allows relative rotation between the driving and driven shafts but also permits axial displacement, usually installed near the drive axle, commonly known as the inner CV joint.

Can You Drive on the Highway with a Nail in the Tire?

Tires with nails that haven't lost air can still be driven on the highway, but attention should be paid to speed and driving distance. Below is relevant information about tires: 1. The role of tires: Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and torques in other directions; transmitting traction and braking torque to ensure good adhesion between the wheels and the road surface, improving the car's power, braking, and passability; working with the car suspension to mitigate impacts during driving and dampen resulting vibrations; preventing severe vibrations and early damage to car components, adapting to the vehicle's high-speed performance and reducing driving noise, ensuring safety, handling stability, comfort, and energy efficiency. 2. Tire lifespan: The lifespan of a tire is related to many factors, such as climate, road conditions, driving habits, installation, maintenance, etc. According to international regulations, if a tire is used normally, it must be replaced when the tread depth wears down to 1.6 millimeters.
