What is Tire Dynamic Balancing?

What is the difference between a central circle and a grid line?

The differences between a central circle and a grid line are as follows: 1. Difference: A grid line is a large yellow grid area where long-term parking is not allowed; a central circle is a small white circular or square (diamond-shaped) area in the middle of an intersection, generally assisting vehicles in turning, and controlling the vehicle's position within the central circle without crossing the line. 2. Road traffic markings: (1) Lines, solid or dashed lines marked on the road surface, curbs, or vertical surfaces; (2) Character markings, text, numbers, and various graphic symbols marked on the road surface; (3) Raised pavement markers, fixed on the road surface, serving as marking blocks, used on highways or other roads to mark centerlines, lane dividers, edge lines, and also to mark curves, entrance/exit ramps, guide lines, road narrowing, and road obstacles.

What Causes the Front Wheels to Squeak When Turning?

Abnormal noises from tires during turns commonly occur in front wheels, primarily due to the following reasons: 1. Specific causes: Excessive accumulation of foreign objects on the left and right front wheel mudguards or sound insulation pads. When the car turns, the tires interfere with these objects, producing abnormal sounds. Long-term buildup of mud and debris on mudguards causes interference with tires. The noise disappears after cleaning. Loose fastening screws on mudguards or sound insulation pads cause them to lift, leading to interference and friction with front wheels during turns, resulting in abnormal sounds. It is necessary to inspect the fastening condition of mudguards and sound insulation pads and eliminate factors such as looseness or lifting. 2. Precautions: Tire noise is a very serious issue. The source of the noise should be promptly identified and resolved as soon as possible. Otherwise, it may cause abnormal tire wear and affect driving safety.

What is the name of the window film that cannot be seen through from the outside?

The window film that cannot be seen through from the outside is called one-way mirror window film. Here are the relevant details: 1. Definition of one-way mirror film: One-way mirror film (also known as one-way film, mirror film, etc.) refers to a film attached to glass that gives the glass a high reflectivity to visible light. One-way mirror film can achieve an effect where, when the outside is brighter than the inside, the one-way mirror glass resembles an ordinary mirror, with the inside scene not visible from the outside, but the outdoor scene visible from the inside. Nowadays, one-way mirror film is commonly used in movies. 2. Advantages of window film: a. Heat insulation and temperature retention; b. Safety and explosion-proof; c. UV protection; d. Anti-glare; e. Easily creates a private space; f. Enhances visual effects; g. High-temperature resistance and fireproofing.

What Causes a Heavy Clutch Pedal in Large Vehicles?

Here are the reasons why the clutch pedal feels particularly heavy in large vehicles: 1. Clutch disc or clutch pressure plate failure. 2. Release bearing failure. Below is a related introduction to clutch operation precautions: 1. Pay attention to posture: Use the ball of your left foot with the heel as a pivot point to press the clutch pedal. When releasing, follow the principle of "fast first, slow second, then linkage." The clutch pedal release process is divided into three stages: initially lift quickly, then slow down when you feel the clutch pressure plate gradually engaging to the semi-linked state, and finally lift the pedal slowly during the transition from semi-linkage to full engagement. 2. Coordinate left and right foot movements: When starting, press the clutch fully with your left foot, shift into first gear, and then press the brake with your right foot. Slowly release the clutch at this point. When you notice slight vehicle vibration, release the brake, and the car will gradually move forward at idle speed.

Where is the throttle body installed?

The throttle body is installed at the position connecting the air filter and the engine cylinder block. Here is some information about the throttle body: 1. The throttle body is one of the most important components in today's electronic fuel injection engine systems. Its upper part connects to the air filter, and the lower part connects to the engine block, serving as the 'throat' of the automobile engine. 2. The throttle body is slightly cylindrical in shape, with a rotating disc at its center that pivots around an axis. As the disc rotates, it controls the cross-sectional area for air passage inside the cylinder, thereby regulating the flow of the air-fuel mixture. Additional information: 1. The throttle body is a controllable valve that regulates the entry of air into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. 2. There are two types of throttle bodies: the traditional cable-operated type and the electronic throttle body. In traditional engines, the throttle body's operating mechanism works via a cable or linkage rod, with one end connected to the accelerator pedal and the other to the throttle linkage plate. The electronic throttle body primarily uses a throttle position sensor to adjust the throttle opening angle based on the engine's power demand, thereby controlling the amount of air intake.
