What does 4WD on a car mean?

4WD on a car stands for four-wheel drive. Four-wheel drive means that both the front and rear wheels of the vehicle have power, and the engine's output torque can be distributed in varying proportions to all wheels depending on the road conditions to enhance the vehicle's driving capability. Four-wheel drive can be further subdivided into four driving modes: full-time drive, part-time drive, on-demand drive, and a hybrid part-time/on-demand drive. Below are detailed explanations: Full-time drive: The front and rear wheels always maintain a four-wheel drive mode. When driving, the engine's output torque is set at a 50:50 ratio between the front and rear wheels, providing excellent driving control and tracking. Part-time drive: The driver can switch between two-wheel drive or four-wheel drive modes by engaging or disengaging the transfer case based on road conditions. This is a common driving mode for off-road vehicles or 4WD SUVs. On-demand drive: Controlled by a computer, the system operates in two-wheel drive on normal roads. If abnormal road conditions or wheel slippage are detected, the computer automatically switches to four-wheel drive by redistributing the engine's output torque to the other two wheels. Hybrid part-time/on-demand drive: This is a driving mode that combines the strengths of both part-time and on-demand drives. Drivers can freely switch between part-time or on-demand drive modes according to their preferences.

How many kilowatt-hours are needed to fully charge a 60V 20A battery?

60V 20A battery requires 1.5 to 2 kilowatt-hours for a full charge. Automotive Battery: Automotive battery is an essential part of a vehicle, which can be divided into traditional lead-acid batteries and maintenance-free batteries. Since the battery uses lead-calcium alloy for the grid frame, the amount of water decomposition during charging is reduced, and water evaporation is also low. Additionally, the sealed structure of the casing minimizes the release of sulfuric acid gas. Therefore, compared to traditional batteries, it has the advantages of not requiring any liquid addition, easy connection to terminal posts, and long power storage duration. Lead-Acid Battery: The structure of a lead-acid battery mainly consists of positive (negative) plates, separators, electrolyte, case, connecting straps, and terminal posts. This battery is a device that converts chemical energy into electrical energy and belongs to the category of direct current power sources.

What do active braking and active safety systems mean?

Active braking refers to a technology where the vehicle can actively generate braking effects to decelerate the car when encountering sudden situations during normal driving, even without adaptive cruise control, thereby enhancing driving safety. Active safety systems include electronic devices such as ABS and ESP. When the vehicle ahead brakes, stops, or encounters other obstacles, this system automatically increases the braking force to help the driver shorten the braking distance before taking action. Automotive safety systems are mainly divided into active safety systems and passive safety systems. The role of active safety is to prevent accidents, while passive safety involves the protection of vehicle occupants or the protection of the impacted vehicle or pedestrians in the event of an accident.

What Causes the Squeaking Noise When Turning the Steering Wheel?

The reason for the squeaking noise when turning the steering wheel is: friction between plastic components. Since the steering wheel is usually made of plastic parts, if the temperature drops, the plastic can harden, naturally leading to possible friction sounds. This noise can also occur when the steering wheel is turned to its limit. Frequently turning the steering wheel to its limit can affect the power steering pump and reduce its service life. If the noise comes from inside the steering wheel, you can remove the steering wheel's clock spring (airbag spiral cable), apply some grease, and check if the noise persists. If it still occurs, replace the clock spring. Be gentle when removing the steering wheel, or disconnect the airbag fuse to prevent the airbag from deploying.

Will points be deducted for a child sitting in the front passenger seat?

No points will be deducted for a child sitting in the front passenger seat. According to the Road Traffic Safety Law, the Implementation Regulations of the Road Traffic Safety Law, and the Ministry of Public Security's Order No. 123 on the Application and Use of Motor Vehicle Driving Licenses, there are no explicit mandatory regulations regarding children not being allowed to sit in the front passenger seat or the mandatory use of child safety seats. Hazards of children sitting in the front passenger seat: 1. When the airbag deploys, the strong impact force may knock the child unconscious; 2. In the event of a collision, a child not wearing a seatbelt is prone to being ejected, and even with a seatbelt, there is still a risk of injury or ejection; 3. Due to children's tendency to be active, they may distract the driver and could play with the gear shift lever.
