Why does the Wuling Hongguang mini make abnormal noises when running?

Wuling Hongguang mini makes abnormal noises when running due to friction between the shock absorber top screw and the vehicle body. The following are the inspection methods for automobile shock absorber faults: 1. Drive the car on a road with poor conditions for 10km and then stop. Touch the shock absorber housing with your hand. If it is not hot, it means there is no resistance inside the shock absorber, and the shock absorber is not working. At this time, you can add appropriate lubricating oil and test again. If the housing becomes hot, it means there is insufficient oil inside the shock absorber, and it should be filled up; otherwise, it means the shock absorber has failed. 2. Press the bumper hard and then release it. If the car jumps 2~3 times, it means the shock absorber is working well. 3. When the car is driving slowly and brakes suddenly, if the car vibrates violently, it means there is a problem with the shock absorber. 4. Remove the shock absorber and stand it upright, clamp the lower connecting ring on a bench vise, and pull and press the shock rod several times. At this time, there should be stable resistance. The resistance when pulling up should be greater than the resistance when pressing down. If the resistance is unstable or there is no resistance, it may be due to insufficient oil inside the shock absorber or damage to the valve parts, and repair or replacement of parts should be carried out.

What is the name of the shield above the tire?

The shield above the tire, the hard outer part is called the wheel arch trim, usually black and protruding in a circle. The soft inner part is called the inner fender liner, also known as the wheel arch interior panel. It is installed for decorative purposes and to meet the personalized needs of the driver. The functions of the shield above the tire: enhance the overall aesthetics of the vehicle body; utilize fluid dynamics to reduce the drag coefficient, making the car drive more smoothly; prevent mud from splashing onto the body or people, which could make them look unattractive; during driving, prevent gravel and mud stirred up by the wheels from splashing onto the car paint. Because tires easily pick up small stones, at high speeds, they can be flung onto the body, chipping the paint. If the wheel arch trim is scratched, it is recommended not to repair it, as the material is plastic and there is no need to worry about rust. Moreover, scratches on the wheel arch trim do not affect the normal driving of the car, making it unnecessary to spend money on repairs. If you really want to fix it, it is recommended to buy a touch-up pen and do it yourself. You can also go to a car beauty shop for repair.

What does the yellow light 'off' on the car dashboard mean?

The yellow light 'off' on the car dashboard means the system is turned off, while 'ON' indicates it is turned on. The 'off' light in a car mainly refers to ESPOFF, where ESP stands for the Electronic Stability Program, an active safety device designed to prevent the vehicle from skidding or losing control. If the ESPOFF light on the dashboard illuminates, it means the vehicle's stability control system is either turned off or malfunctioning. If you accidentally press the ESPOFF button in the car, simply press it once more to reactivate the ESP. However, if the ESPOFF light is on due to a system malfunction, it is advisable to take the vehicle to a 4S shop for inspection and repair promptly. There are many reasons why the warning light may come on, including wiring faults, sensor damage, incorrect signals from the electronic control unit, or a weak battery. ESP is particularly sensitive to oversteering or understeering. For example, when a car oversteers (turns too sharply) on a slippery road, it may skid to the right. The sensors detect the skid and quickly apply the brakes to the right front wheel to restore traction, creating an opposite torque to keep the car in its lane. The difference between a car with ESP and one with only ABS and ASR is that ABS and ASR react passively, while ESP can detect and analyze driving conditions and correct driving errors proactively, preventing potential accidents.

Can 95 and 98 Octane Gasoline Be Mixed?

92 octane gasoline and 95 octane gasoline cannot be mixed because their isooctane content differs. 92 octane gasoline is suitable for engines with low compression ratios, while 95 octane gasoline is suitable for engines with high compression ratios. If 92 octane gasoline is added to a car that requires 95 octane, abnormal combustion may occur, leading to knocking. Knocking not only damages the combustion chamber but also directly affects the normal operation of the engine, potentially causing severe engine damage. Conversely, adding 95 octane gasoline to a car that requires 92 octane will not harm the engine, but since 95 octane is more expensive, it would result in unnecessary costs. Differences between 92, 95, and 98 octane gasoline: Standard gasoline consists of isooctane and n-heptane. Isooctane has good anti-knock properties, with an octane rating of 100, while n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with an octane rating of 0. If gasoline is labeled 92 octane, it means the gasoline has the same anti-knock properties as a standard fuel containing 92% isooctane and 8% n-heptane. The same principle applies to 95 and 98 octane gasoline. What to do if the wrong gasoline is added: If gasoline with a higher octane rating than required is added (e.g., adding 95 octane when 92 octane is specified), simply use up the fuel and refill with the correct 92 octane gasoline afterward. If gasoline with a lower octane rating than required is added (e.g., adding 92 octane when 95 octane is specified), you can add a high anti-knock fuel additive. Alternatively, you can drain the fuel tank and refill with the correct 95 octane gasoline. To determine the appropriate gasoline for your car, refer to the vehicle's user manual or check the fuel grade indicated on the fuel filler cap.

What does a 3-lock off-road vehicle mean?

A 3-lock off-road vehicle refers to a car equipped with three differential locks: front axle differential lock, center differential lock, and rear axle differential lock. Having these three differential locks indicates that the vehicle possesses strong off-road performance and robust off-road hardware. Below is an introduction to off-road vehicles: 1. Definition: An off-road vehicle is specifically designed for off-road use, primarily referring to vehicles capable of traversing rough terrain. 2. Features: Its main characteristics include a ladder-frame chassis, four-wheel drive, high ground clearance, tires with excellent traction, elevated exhaust pipes, high horsepower, and sturdy bumpers.

Do I Need to Change Back If the Tire Is Mounted Backwards?

Tires mounted backwards need to be corrected, and during installation, the tire's specified mounting direction should be strictly followed. Here are the specific reasons: 1. Tire tread design: The tread pattern and its orientation have a directional design, which plays a crucial role in water drainage and anti-slip performance during normal driving. 2. Reversed mounting affects braking: Mounting tires backwards reduces the vehicle's grip, causes uneven resistance on both sides, thereby affecting braking performance, accelerates tire wear, and may lead to vehicle deviation and unstable steering.
