Changan Unit tires are run-flat tires. Here is the relevant introduction: 1. Introduction: The Changan UNI-T adopts a new borderless design language, and its futuristic styling design has been called a "mass-produced concept car" by netizens. Many groundbreaking design methods can be seen on the Changan UNI-T. 2. Extended information: If a single tire bursts, causing damage to components such as the rim, the insurance company will not compensate. Because tires are consumables and are not covered by insurance. However, if a traffic accident is caused by a tire burst, resulting in other losses, as long as the owner has purchased the corresponding car insurance, the insurance company must compensate.

What Causes the Intermittent Failure of Tianjin Clutch?

The reasons for the intermittent failure of Tianjin clutch include hydraulic oil leakage or air entering the pipeline, severe wear of the clutch plate, broken cable, or foreign objects stuck under the pedal. Functions of the Clutch: Ensures smooth car starting. It is undoubtedly essential to start the engine before the car moves. When the car starts, it accelerates suddenly from a stationary state. If the transmission system is rigidly connected to the engine, normal starting would be impossible due to the significant inertia from stationary to moving and the large torque resistance generated by the engine. Ensures smooth gear shifting. The car will shake when the clutch is released to a certain extent, requiring acceleration to start. The car will not roll back in a semi-linked state, especially during hill starts. The clutch is used for gear shifting. Keeping the foot on the clutch for extended periods will shorten its lifespan. How to Maintain the Clutch: The most important aspect of clutch maintenance is to avoid frequently keeping the foot on the clutch pedal during daily use. When releasing the clutch, follow the steps of quick release, pause, and slow release. Other maintenance methods include removing oil or grease from the friction plate and pressure plate in the clutch when they are contaminated with oil or rust.

What is tire noise?

Tire noise is generated by the friction between the tires and the road surface when the vehicle is driving at high speeds. The level of tire noise depends on road conditions and vehicle conditions—the worse the road condition, the louder the tire noise. Additionally, there is a significant difference in tire noise between asphalt and concrete road surfaces. The specific factors affecting tire noise are as follows: Road surface structure: Friction and vibration occur when the tire tread meets the road surface. Tire pressure: Abnormal tire pressure affects tire noise, which is also why new cars may have louder tire noise. Tire tread design: This plays a dominant role in tire noise. Tire size directly determines the level of tire noise: Generally, the larger the tire size, the louder the tire noise.

Are there any requirements for the photo when renewing a driver's license?

Article 57 of the "Traffic Regulations and Penalty Rules": Motor vehicle drivers should apply for license renewal at the vehicle management office where the driver's license was originally issued or at any other vehicle management office within 90 days before the expiration of the driver's license. When applying, the applicant must fill out an application form and submit the following documents: the original and copy of the driver's license; the original and copy of the ID card; two or more one-inch color front-facing photos with a white background and no hat; and a medical certificate issued by a county-level or higher medical institution or a military medical institution at the regimental level or above. For those applying for a small automatic passenger vehicle for the disabled, a medical certificate issued by a specialized medical institution designated by the provincial health authority must be submitted. Matters related to renewing an expired driver's license: You can apply for a driver's license renewal within 90 days of its expiration. You can apply at the local vehicle management office or online. When renewing, you need to fill out the renewal application form and bring your ID card, driver's license, medical examination report, and other relevant materials. For renewing the driver's license, recent one-inch color photos with a white background and no hat must be used. If the photos are not qualified, you need to retake them. After the motor vehicle driver's license is renewed, the original license becomes invalid and cannot be used again. You must properly keep the driver's information on the license and not discard it casually to avoid information leakage, which could cause issues when using the driver's license. If your driver's license has expired, the traffic police may impose a fine but will not deduct points. There is also a latest deadline for renewal: if the license has been expired for less than one year, you can follow the normal renewal process; if it has been expired for one to three years, the license will be canceled, but you can retake the subject one exam to regain it; if it has been expired for more than three years, the license will be canceled. About renewal: Before renewal, all traffic violations related to the driver's license must be resolved; otherwise, the application will not be accepted. Processing location: Driver's license renewal can be processed at the vehicle management office where the license was originally issued or at any other vehicle management office. Renewal of a motor vehicle driver's license can also be done through mobile apps: for iOS 15 and above, use the Traffic Management 12123 app (V2.8.1B437); for Android 12 and above, use the Traffic Management 12123 app (V2.8.1B274). On the main page, select "Driver's License Replacement and Renewal" to effectively renew the motor vehicle driver's license. Photos and medical certificates required for renewal can be prepared by yourself. If you are worried about their qualification, you can process them directly at the traffic police office to avoid delays.

What Causes a Car Fan to Keep Running?

Fan keeps running because the turbo fan is cooling down the turbo, which is a normal phenomenon. Fan delayed shutdown: During operation, the temperature distribution in the entire water channel is not uniform, and there are localized relatively high temperature points. When the water pump stops running, these heat cannot be dissipated, so the fan delays shutdown for the purpose of cooling, which is a normal phenomenon. Sensor commands the fan to run: Although the car is turned off, the temperature has not yet dropped. The electric fan is commanded by the sensor. In summer, if the car is parked under the sun, the electric fan will still rotate even if the car is not running, as long as the temperature reaches a certain degree. This situation is very normal.

Is the forward gear D or R?

Forward gear is D, where D stands for Drive. Below are the details about the forward gear: Forward Gear: D (Drive) is the forward gear, also known as the driving gear. In this gear, the transmission automatically shifts between 1-overdrive (equivalent to 1-4 gears) based on speed and throttle conditions. This gear is used for normal road driving. Other Gears: P stands for Parking gear, used when parking (when the engine is off); R stands for Reverse gear; N stands for Neutral, which is the same as the neutral in manual transmissions and is used for brief stops; S stands for Sport mode, where the transmission can shift freely; L stands for Low gear, where the transmission stays in 1st gear without shifting up; OD stands for Overdrive, used for high-speed driving.

What is the reason for the car not stalling but not moving when accelerating?

The reasons for the car not stalling but not moving when accelerating are as follows: Intake system issues: The air filter is the most frequently cleaned and replaced among the three filters. If the air filter is clogged or the throttle system is blocked, the intake volume will decrease, combustion will be insufficient, power will drop, and the car won't move even when the accelerator is pressed hard. Ignition system issues: If the car doesn't move when accelerating and emits black smoke, it is likely that there is a problem with the ignition system. Carbon buildup on the spark plugs of the ignition system can lead to poor ignition, resulting in decreased power and persistently high fuel consumption. To keep the car running smoothly, regular replacement of spark plugs is very important.
