Why Did the Windshield Crack by Itself?

Windshields can crack by themselves due to significant temperature differences between the interior and exterior. Windshields are made of laminated glass or tempered glass, composed of silicon oxide, sodium oxide, calcium oxide, magnesium, etc. Laminated glass involves bonding a transparent adhesive plastic film between two or three layers of glass, combining the toughness of plastic with the hardness of glass to enhance its resistance to breakage. Tempered glass is produced by quenching ordinary glass to create internal stress, thereby increasing its strength. When impacted and broken, tempered glass shatters into small, blunt-edged fragments that do not harm occupants.

What is the normal oil temperature for a car?

For a car, the normal oil temperature ranges between 70 to 90 degrees Celsius. Under high engine load conditions, it may reach 100 to 110 degrees Celsius. Functions of engine oil: 1. Reduce wear between the piston and cylinder, as well as between the main shaft and bearing bush, providing lubrication; 2. Assist in cooling the engine internally; 3. Clean carbon deposits, sludge, and metal wear particles from engine components; 4. Minimize gas leakage and prevent external contaminants from entering; 5. Absorb shock and reduce the load on pistons, piston rings, connecting rods, and crankshaft bearings; 6. Decrease frictional resistance, conserve energy consumption, and minimize wear.

What is the difference between LED lenses and xenon lenses?

LED lenses and xenon lenses differ as follows: 1. Xenon lights are extremely bright. Compared to halogen lights, they not only enhance brightness at night but also increase the illumination distance, making them suitable for upgrading high beams. 2. LED car lights not only offer excellent brightness but also provide a color closest to natural light. They can match halogen lights in beam pattern while delivering purer color temperature. Driving with LED car lights at night can effectively reduce eye fatigue, making them suitable for upgrading low beams. Here is more information about LED lenses and xenon lenses: (1) The biggest advantage of xenon lights is their low wattage and high brightness, especially effective for nighttime illumination. Xenon lights do not have filaments, eliminating the issue of burnout and extending their lifespan to three times that of regular car lights. However, xenon lights have a longer startup time, requiring about five to ten seconds to reach full brightness after being turned on. In rainy or foggy conditions, the light tends to scatter, resulting in poorer illumination compared to original halogen lights. (2) Upgrading to LED bi-xenon lenses requires replacing the original car headlights, which involves disassembling and reassembling the original headlights—a complex and tedious process. If the modification is not done properly, it may lead to mismatched circuits, triggering warning lights or causing high-frequency pulse interference with the vehicle's electrical systems. Therefore, it is recommended that car owners seek professional modification services from specialized shops.

What does the 4S in automotive 4S stand for?

4S represents the initials of four English words. These four S-starting English words respectively signify the following meanings: Sale (vehicle sales), Sparepart (auto parts), Service (after-sales service), and Survey (information feedback). Extended information: 1. Sale: The so-called "sale" mainly refers to automobile sales, which is the fundamental business of every 4S store and also the basic function of all 4S stores. Consumers come to 4S stores primarily to purchase cars. In the sales hall, consumers can not only see various car models most intuitively but also test drive them. 2. Sparepart: Sparepart represents auto parts. This is a relatively important service among many automobile brand 4S stores because it is the auto parts business that brings higher profits to 4S stores. 3. Service: The service in 4S stores mainly refers to the after-sales service of automobiles. Like auto parts, after-sales service is also a highly profitable business for 4S stores. Although the maintenance and repair prices of 4S stores are higher than those of private repair shops, many car owners still prefer 4S stores for safety considerations. 4. Survey: That is, information feedback. In fact, information feedback is an important part of brand building, and the same goes for automobiles. Because only by truly understanding consumers' thoughts and needs can we continuously optimize our products and services to attract more consumers.

How to Check if the Car Battery Has Power?

Methods to check if the car battery has power are: 1. Observe the inspection window on the battery—green indicates normal, black means it needs charging, and white signifies damage; 2. Check the indicator window on the battery—blue or green color indicates normal, while white means no power; 3. Press the horn—a loud sound indicates power, while a weak sound suggests low power; 4. Observe the battery warning light on the dashboard—if it stays lit, it means the battery is out of power. Function of the battery: It stores electrical energy to supply power for car starting, ignition, lighting, signals, and audio-visual equipment. Working principle of the battery: Car batteries use lead-acid batteries based on the primary cell principle. When the load is connected, the lead on the negative plate reacts with sulfuric acid to form lead sulfate and lose electrons, while the lead oxide on the positive plate reacts with sulfuric acid to form lead and water, gaining electrons, thus generating electric current.
