The function of a central differential lock: It can enhance the vehicle's off-road capability on poor road surfaces. When one of the vehicle's drive axles spins freely, it can quickly lock the differential, turning the two drive axles into a rigid connection. This allows most of the torque to be transferred to the non-slipping drive axle, fully utilizing the traction to generate sufficient driving force, enabling the vehicle to continue moving. The central differential lock, also known as the central differential locker, is a locking mechanism installed on the central differential, used in four-wheel-drive vehicles. Different differentials employ various locking methods. Common differential locks include the following types: forced locking, high-friction self-locking, jaw coupling, Torsen, and viscous coupling.

Is Yadi brand battery lead-acid or lithium battery?

Yadi brand battery is a lead-acid battery. Currently, lead-acid batteries are still the main type of battery used in electric vehicles, while lithium batteries are relatively rare. Lithium batteries are small in size, light in weight, and have a long lifespan, but they are relatively more expensive. Here is some extended information: 1. Battery-related content: A battery refers to a cup, tank, or other container or part of a composite container that contains an electrolyte solution and metal electrodes to generate current, and can convert chemical energy into electrical energy. It has positive and negative poles. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy, such as solar cells. The main performance parameters of batteries include electromotive force, capacity, specific energy, and resistance. 2. Using batteries as an energy source: Using batteries as an energy source can provide stable voltage, stable current, long-term stable power supply, and current that is less affected by external factors. Moreover, batteries have a simple structure, are easy to carry, and have simple and easy charging and discharging operations. They are not affected by external climate and temperature, and their performance is stable and reliable, playing a significant role in various aspects of modern social life.

What causes the squeaking noise resembling brakes after the car starts moving?

The main reason for the abnormal noise resembling brakes after the car starts moving is that the speed of releasing the brakes is too slow when starting. The specific reasons are as follows: 1. The cause of the noise is related to the brakes: The abnormal noise resembling brakes after the car starts moving is a normal phenomenon. Generally, when starting and releasing the brake pedal, the engine has sufficient power to drive the car forward, but the brake pedal is not completely released. This causes the moving wheels to be held by the brake system, resulting in abnormal noise. 2. The reason why manual transmissions do not produce such noise: When the brake is released in a manual transmission car, the transmission does not generate output power. By the time the vehicle starts moving, the brake has already been completely released, so no abnormal noise occurs.

Is It Normal for the Engine Compartment to Be Hot?

It is normal for the engine compartment to be hot, but attention should be paid if the temperature rises to the point where the water temperature warning light comes on. Here are the solutions for overheating: 1. Sudden overheating of the engine while driving: First, pay attention to the ammeter's behavior. If the ammeter does not indicate charging when the accelerator is pressed, and the needle only swings intermittently from a discharge of 3A-5A back to the "0" position, it indicates that the fan belt has broken. 2. If the ammeter indicates charging: Then, turn off the engine and touch the radiator and the engine by hand. If the engine temperature is too high while the radiator temperature is low, it means the water pump shaft and impeller have loosened, interrupting the cooling water circulation. If the temperature difference between the engine and the radiator is not significant, check for any serious leaks in the cooling system. 3. Cooling water: If the temperature rises to boiling shortly after starting, it is mostly due to the thermostat's main valve falling off and blocking the radiator's inlet pipe, hindering the major circulation of the cooling water. If boiling is noticed while driving, stop the vehicle immediately, let the engine run at low speed until the water temperature normalizes, and then turn off the engine for inspection.

What is the difference between Li and i?

L stands for Large in English, meaning big or extended. i represents gasoline direct injection, and Li stands for the extended version with gasoline direct injection. Taking BMW Li and BMW i as examples, the differences are explained in detail: 1. BMW Li is a model with an extended wheelbase, while BMW i is the standard wheelbase model. The wheelbase is the most fundamental factor affecting passenger space. A longer wheelbase increases the longitudinal space for passengers, significantly improving legroom, which affects the comfort of vehicle seating. 2. The BMW Li model better meets the psychological standards of Chinese consumers and offers more thoughtful humanized designs for rear passengers, making it suitable as a business vehicle with features that cater to both family and commercial use. Generally, Li models are slightly more expensive than i models.
