What is the SOS system in a car?

What are the emergency measures when a tire suddenly bursts while driving?

Emergency measures when a tire suddenly bursts while driving are as follows: In the event of a front tire blowout, firmly grip the steering wheel to keep the vehicle moving as straight as possible, while avoiding sudden braking. Since most vehicles are front-wheel drive, jerking the steering wheel or braking suddenly may cause the vehicle to roll over. While maintaining control of the vehicle, apply the brakes gently to gradually reduce speed, then pull over to the side of the road at a safe speed. After stopping, set up a warning triangle as soon as possible to alert approaching vehicles and prevent secondary accidents. Rear tire blowouts are relatively less dangerous, but the handling method is similar. Before driving, it is advisable to check the vehicle's condition, including tire pressure, fuel level, and oil status, to prevent accidents. Analysis is as follows: Do not brake to reduce speed under any circumstances, as the vehicle's center of gravity will shift toward the side of the blown-out tire, and braking will exacerbate this shift, potentially causing a rollover. When a tire blows out, it is crucial to maintain control of the steering wheel and make appropriate corrections. Generally, when a high-speed blowout occurs, the vehicle will rapidly veer toward the side of the blown-out tire. If you cannot remain calm and apply the correct steering correction, the vehicle will be unable to maintain its direction, swaying dangerously back and forth on the road.

What are the main materials of brake pads?

Main materials of brake pads: 1. Resin-based brake materials; 2. Powder metallurgy brake materials; 3. Carbon composite brake materials; 4. Ceramic-based brake materials. Automobile brake pads are generally composed of steel plates, bonded heat insulation layers and friction blocks. The steel plates are painted to prevent rust, and the temperature distribution during the painting process is detected by SMT-4 furnace temperature tracker to ensure quality. Automobile brake pads, also known as automobile brake linings, refer to the friction materials fixed on the brake drum or brake disc rotating with the wheels. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration.

What Causes the Speaker on One Side of the Car Door Panel to Stop Working?

Speaker malfunction may be caused by poor sealing leading to moisture, poor contact at the electromagnetic coil terminals, or contact point erosion. Poor Sealing Leading to Moisture: Although the speaker interior is sealed, if the sealing is not tight, moisture can enter during car washing or water vapor in the internal space can cause the contacts to become damp, preventing normal operation. Poor Contact at the Electromagnetic Coil Terminals: Some speakers have aluminum metal rivet crimp connections for the enameled wire terminals of the internal electromagnetic coil, rather than secure welded connections. If the insulation varnish on the wire ends is not properly removed or the rivet crimping is not secure, it can easily lead to intermittent contact faults, resulting in poor speaker performance. This type of fault is due to speaker quality issues and cannot be repaired; only replacement with a new part is possible. Contact Point Erosion: Prolonged use of the horn can cause the speaker contacts to erode, creating resistance. This reduces the current flowing through the electromagnetic coil, weakening the electromagnetic force and preventing it from attracting the armature to drive the diaphragm for normal vibration. This results in a hoarse sound or even complete silence. However, when the horn is pressed continuously, a momentary strong current passing through the resistance can still allow normal operation, leading to intermittent functionality.

What year does the 10th digit 'M' in the VIN represent?

The 10th digit 'M' in the VIN represents the year 2021. Below is relevant information about the VIN: VIN location: For trucks and large vehicles, it is generally located on the right side of the vehicle frame at the rear; for passenger cars, it is usually found in the lower left corner of the windshield (under the wiper deflector) or on the door frame below the passenger seat; for motorcycles, turn the handlebars fully to one side, and you'll find a nameplate below the odometer with the VIN; the vehicle's registration certificate also clearly states the VIN in the 'VIN' section. VIN content: The VIN, or Vehicle Identification Number, is like a vehicle's ID card—just as every person has their own identity card, each vehicle has a unique VIN composed of 17 digits or letters. People can learn a lot about a vehicle from its VIN, such as its place of manufacture, vehicle type, model year, assembly details, etc. Digits 1-3 represent the manufacturing location, brand, and type; digits 4-8 indicate vehicle characteristics; digits 9-11 denote the check digit, model year, and assembly plant; digits 12-17 represent the serial number, which is the last 6 digits of the VIN.

What Causes Engine Vibration After Starting?

Reasons for engine vibration after starting: When starting the engine, the engine does not operate smoothly, and some vibration may occur at this time. Some engines with poor smoothness may continue to vibrate after starting, which is normal. Engines with good smoothness will not vibrate after starting. Most cars use inline four-cylinder engines, which may also exhibit slight vibration after starting. If the engine vibration becomes more pronounced, it may be due to issues with the engine mounts. The engine mounts, made of rubber, connect the engine to the frame and help prevent the direct transmission of engine vibrations to the vehicle body.
