Why Do Dash Cam Memory Cards Frequently Get Damaged?

The frequent damage to dash cam memory cards is mainly due to two reasons. Below is a detailed explanation of the common causes of memory card damage: 1. Poor quality of the memory card. 2. Issues with the dash cam, such as high voltage or current, which may burn out the memory card. Additional tips for handling frequent memory card damage in dash cams: 1. It is recommended to use high-speed memory cards with a write speed of at least 20MB/s, and regularly format the card (once every 3 months), replacing it with a new one after a year. Additionally, try to lower the resolution while maintaining clarity. 2. Do not randomly insert or remove the TF card while the dash cam is reading or writing data. Always turn off the dash cam before inserting or removing the memory card. Forcibly removing the card can easily damage it, as memory cards do not support hot-swapping. In short, it is best to minimize inserting and removing the memory card from the dash cam. Generally, a memory card used in a dash cam can last several years without any issues.

How much does an 825-20 tire weigh?

Tire weight is not fixed. The 825 tire can bear a load of 15-18 tons, but for safety reasons, it is generally recommended to carry a load of less than 15 tons. Each tire has its own load-bearing capacity, and different truck models may have significant variations in their load-bearing capabilities. It is essential to adhere to the specified load index and avoid overloading. Additional content: Daily tire maintenance methods are as follows: 1. Monthly inspection: Check the air pressure of all tires, including the spare tire, at least once a month when they are cold. 2. Avoid speeding: Do not exceed the reasonable speed required by driving conditions and legal limits (e.g., slow down or avoid obstacles such as rocks or potholes ahead). 3. Regular wheel alignment: Regular wheel alignment and balancing are crucial for ensuring driving safety and achieving optimal mileage. 4. Regular tire rotation: To achieve even wear and extend tire life, rotate the tires approximately every 8,000 to 10,000 kilometers. 5. Prevent tire erosion: Protect tires from sunlight, oil, acid, and hydrocarbon erosion. 6. Develop good habits: Cultivate good driving habits, such as avoiding sudden braking and sharp steering.

Consequences of Not Changing Antifreeze for Five Years?

Not changing the antifreeze for five years will cause the water in the antifreeze to evaporate, leading to changes in the freezing point and affecting the antifreeze's performance. It will fail to provide corrosion resistance, rust prevention, and rust removal functions for the engine, thereby impacting the engine's service life. It may also increase the viscosity of the antifreeze and reduce its cooling efficiency. Antifreeze Replacement Cycle: For vehicles that operate for extended periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned. Antifreeze Composition: The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances.

What is the difference between electronic fuel injection and carburetor in motorcycles?

The differences between electronic fuel injection and carburetor in motorcycles are as follows: 1. Working principle: The carburetor operates passively, while electronic fuel injection works actively. The carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the engine's operation, utilizing the kinetic energy of the incoming airflow to atomize the gasoline. Its working method is relatively passive and cannot actively control the process. In contrast, electronic fuel injection can regulate the fuel supply, actively increasing or decreasing it, making the working method more controllable. 2. Fuel consumption: Electronic fuel injection is more fuel-efficient than the carburetor. The carburetor supplies fuel to the engine mechanically, and the relationship between fuel supply and engine speed or throttle opening can only be linear, making it impossible to ensure the ideal air-fuel ratio under all working conditions and environments. The carburetor cannot adapt to changes in engine state, leading to increased fuel consumption. In electronic fuel injection, the dedicated software in the microcomputer can intelligently control the fuel supply and ignition in real-time, providing precise fuel delivery. This ensures that the air-fuel ratio and ignition timing can always be optimized under any working condition or environment, thereby reducing fuel consumption and improving overall performance.
