Electric Four-Wheel Drive: The switching between two-wheel drive and four-wheel drive is controlled by a computer chip. On normal road surfaces, the vehicle operates in two-wheel drive mode. When encountering off-road conditions or wheel slippage, the computer detects and automatically distributes power to the other two wheels. Below is additional information: 1. Part-Time Four-Wheel Drive: Electric four-wheel drive (automatic transmission) is electronically controlled, whereas manual four-wheel drive (manual transmission) is fully mechanically and manually controlled. Since electric four-wheel drive uses a computer chip to control the switching between two-wheel and four-wheel drive, it not only requires higher quality automotive components but also depends on the quality of the control program for the intelligence of the drive mode switching in part-time four-wheel drive systems. 2. Electric Four-Wheel Drive Has Certain Disadvantages: Currently, some drivers favor electric four-wheel drive. However, although it can enhance the vehicle's control over the tires, electric four-wheel drive still has certain limitations on high-intensity unpaved roads. With today's advanced technology, electric four-wheel drive, as an emerging technology, will continue to improve and advance on existing technologies.

What Causes the Vehicle to Continue Sliding Forward When Braking Hard?

During emergency braking, to prevent wheel lock-up, the ABS system intervenes, allowing the wheels to continue rotating, which results in the vehicle sliding forward. Below is relevant information about ABS: 1. Function of the vehicle ABS system: The Anti-lock Braking System (ABS) automatically controls the braking force during vehicle braking to prevent wheel lock-up, maintaining a state where the wheels are both rolling and sliding (with a slip ratio of about 20%), ensuring maximum traction between the wheels and the road. The ABS system activates only during emergency braking, continuously switching between the critical points of wheel sliding and rolling, effectively reducing braking distance and preventing skidding during sudden stops. This system significantly enhances driving safety, making ABS a mandatory feature in modern vehicles. 2. Components of the ABS system: Includes the ABS module, ABS master cylinder, hydraulic lines, wheel speed sensors, etc.

Low-pressure tires: Inflation pressure ranges from 0.1471 to 0.490 MPa; Low-pressure tires are generally suitable for private vehicles, with typical inflation pressure for family cars being 0.2~0.25 MPa. High-pressure tires: Inflation pressure ranges from 0.5 to 0.7 MPa. High-pressure tires are suitable for large trucks/buses, with inflation pressure typically around 0.5 MPa, while steel-belted tires can be appropriately increased to about 0.6 MPa.

Can Motorcycle Keys Be Duplicated?

Most lost motorcycle keys can be duplicated. The owner can drive the motorcycle to a professional locksmith to have the ignition switch removed, and then a new key can be made. If the key is not duplicated, the only option is to replace the lock. Since the motorcycle's fuel tank cap and ignition switch use the same key, both locks would need to be replaced in this case. Pay attention to the key material: Some key blanks may appear to be made of metal but are actually of very poor quality. They may break after a short period of use, even before the teeth wear out. Therefore, it is essential to carefully check whether the key is made of pure metal. Identifying quality: The quality of a key can be distinguished by simply dropping it lightly onto a hard surface such as a concrete floor or glass tabletop. A good metal blank will produce a crisp metallic sound, while a poor-quality one will make a dull, muffled noise similar to the sound of plastic hitting a hard surface.
