Failure to start may be caused by the following faults: 1. Circuit or electronic faults: Circuit faults include: blown fuse, open circuit in high-voltage coil, open circuit in low-voltage circuit, detached central ignition wire, leaking distributor rotor, or damaged spark plugs. Electronic faults mainly refer to the malfunction of the central computer control board. 2. Fuel system faults: Stalling caused by fuel system faults often comes with symptoms like weak engine power or the accelerator pedal feeling spongy. Possible locations of fuel system faults include: fuel pump failure, blocked fuel line, clogged fuel filter, carburetor failure, or damaged injectors, etc. 3. Mechanical faults: Common mechanical faults include: timing belt (chain) breakage, cylinder leakage causing no pressure, etc.

How Many Turns of the Steering Wheel for a U-Turn?

When making a U-turn, the steering wheel is typically turned more than 90 degrees and then adjusted to half a turn, aligning the front of the vehicle with the center of the road. Here is some related knowledge about making U-turns with a car: Wide Roads: You can use the method of making a wide turn. First, position the car slightly towards the opposite side of the U-turn, then turn on the signal light, confirm safety, and turn the steering wheel fully to complete the U-turn. Narrow Roads: Use a combination of forward and reverse movements to make the U-turn. When turning for the U-turn, as the front wheels approach the roadside or the front of the vehicle nears an obstacle, press the clutch, lightly apply the brake, and before the vehicle comes to a complete stop, quickly turn the steering wheel in the opposite direction to the maximum. Turn the front wheels to the new direction needed for reversing, then immediately bring the vehicle to a stop.

Within how many kilometers should the first car maintenance be performed?

Different car manufacturers specify different maintenance intervals, generally the first maintenance is recommended at 3,000 to 5,000 kilometers or within six months. The items for the first car maintenance are as follows: Engine oil and filter replacement: The first car maintenance usually requires changing the engine oil and filter. The purpose of changing the engine oil is to ensure better lubrication for the engine, as the lubricating effect of the oil deteriorates after a period of use, hence the need for replacement. Engine inspection: Check the working condition of the engine, such as whether all pipe connections are normal, if there are any leakage points, whether the engine sounds normal during operation, and if there are any abnormal noises, etc. Brake pads and other inspections: Inspect the wear level of the brake pads and tires. After lifting the vehicle, check if there are any deformations or damages to the chassis caused by collisions or scrapes.

Can a Dash Cam Use an 8GB Memory Card?

Yes, it can. Most dash cams use loop recording, where the recorded videos are stored on the memory card for a certain period, ranging from 1 minute to 3 minutes, or 5 minutes to 10 minutes. When the memory card is full, new recordings will overwrite the old video clips (except for locked videos). The advantage of this mechanism is that it prevents the dash cam from stopping recording due to insufficient storage space. However, an 8GB card has relatively small capacity. If there are no specific requirements for video quality, clip duration, or time span, an 8GB card is sufficient for daily driving. Nevertheless, it is recommended to purchase a memory card with a larger capacity. The larger the memory, the more videos can be stored, and the longer the recording time. Taking 1080P video as an example, an 8GB memory card can typically record about 60 minutes of video, while a 16GB card can record 100 minutes, a 32GB card can record 200 minutes, and a 64GB card can record 400 minutes.

Does Rainy Weather Affect Vehicle Painting?

Rainy weather does have a certain impact on vehicle painting. Below is some information about vehicle painting: 1. Reason: Rainwater generally contains acidity, and acid rain can cause significant damage to the car paint, leading to oxidation of the paint surface and loss of gloss. 2. Consequences: The increased humidity after rain can affect the drying speed of freshly painted surfaces, but the moisture also reduces the amount of dust in the air, which is beneficial for painting. 3. Precautions: (1) If the car has just been painted, avoid contact with water and dust on the newly painted areas; (2) It is best not to drive the car out on rainy days, as the fresh paint is still delicate and contact with rainwater can leave marks that may be difficult to remove, even with polishing. Parking in a garage at night is recommended; (3) Sunlight is not a concern, as it only speeds up the drying process of the paint, which is beneficial; (4) Avoid exposing the newly painted areas to chemicals and oil stains.

Can Old License Plates Be Used on New Cars?

Old license plates can be used on new cars. The condition that must be met is that the license plate number has been continuously used under the original owner's name for at least one year, and it will automatically be retained for one year. The following are relevant matters to note regarding the use of old license plates on new cars: 1. Situations where legal entities cannot inherit: If the original owner is a unit (company), after the vehicle is transferred, the license plate is retained under the name of the unit (company), not under the name of the company's legal representative. The legal representative has no right to inherit it. 2. Situations where natural persons cannot inherit: If the vehicle undergoes a transfer of marital property, and the license plate is transferred from one spouse to the other, it must be used under the new owner's name for at least one year before it can be retained. Even if the original owner passes away, the license plate number is not included in the inheritance. 3. Archiving period: After the old license plate is transferred, it cannot be used immediately; there is typically a 3-business-day archiving period.

What to Do When the Outside of the Windshield Is Blurry?

Open all the car windows. When the air inside the car circulates with the outside air, the fog on the car's front windshield can quickly disappear. Below is relevant information about the car's front windshield: 1. The windshield has curvature: Car windshields have curved deformations at the edges where they contact the car body. This curvature causes external scenery to distort when viewed through it, affecting the visual perception of passengers inside the car and creating a deceleration effect. It's similar to looking at a newspaper through a magnifying glass—the scenery in the middle appears to move slowly, while the scenery at the edges appears to move quickly. Additionally, the edges of the windshield have fading dotted black decorative borders, which also contribute to this effect. 2. Function of the curvature: While driving, the curvature of the windshield causes the movement of reference objects on both sides of the car to gradually slow down, creating the perception that the front windshield has a deceleration effect. This shares some similarities with a magnifying glass.
