The differential enables the left and right (or front and rear) drive wheels to rotate at different speeds. The following are the functions of a differential: 1. When the car is turning or driving on uneven road surfaces, the left and right wheels roll at different speeds, ensuring that both drive wheels perform pure rolling motion. 2. The differential is designed to adjust the speed difference between the left and right wheels. 3. In four-wheel drive systems, to drive all four wheels, they must be connected. If all four wheels are mechanically connected together, the car cannot rotate at the same speed when driving on curves. To allow the car to maintain a relatively consistent rotational speed during curve driving, a center differential is added to adjust the speed difference between the front and rear wheels.

What license plates are used on hybrid vehicles?

Hybrid vehicles mainly come in three types: plug-in hybrid, gasoline-electric hybrid, and range-extended hybrid. Among these, only plug-in hybrids are allowed to apply for green license plates, while other hybrid vehicles use blue license plates, the same as those used by conventional fuel-powered vehicles. Most gasoline-electric hybrid vehicles are fuel-powered cars, and their license plates are the same blue plates as fuel-powered vehicles. Relevant information is introduced as follows: 1. Gasoline-electric hybrids are similar to gasoline-powered cars in that they refuel at gas stations, requiring no change in driving habits. Governments and businesses promoting such products also do not need to invest in building new charging facilities or gas stations. 2. They offer high fuel efficiency and superior driving performance. The engines of gasoline-electric hybrid vehicles use fuel, but during startup and acceleration, the assistance of an electric motor can reduce fuel consumption. The internal combustion engine can be shut down, allowing the battery to drive alone, achieving "zero" emissions. 3. Their power performance is superior to that of pure internal combustion engine cars of the same displacement, especially during startup and acceleration, where the electric motor can effectively compensate for the low-speed torque deficiency of the internal combustion engine. 4. They reduce mechanical noise inside the vehicle and use the electric motor during low-speed operation or idling.

How to Install the Parking Warning Light for Manual Transmission?

Every vehicle comes with a parking warning light pre-installed, so no additional installation is required. The parking warning light, also known as the hazard lights or emergency flashers, is used to signal, warn, or alert other drivers in the event of an accident or other emergency situations. Below are the relevant details: The warning light is typically a red button, usually located in a prominent position on the center console. It features a white double-triangle border on the surface and is relatively large in size. To activate the warning light, simply press the button once to turn it on, and press it again to turn it off. The parking warning light is essentially the hazard warning light (commonly referred to as "hazard lights"). Situations for using the hazard warning light: 1. Driving in foggy conditions: Due to poor visibility, not only should the hazard lights be turned on, but the fog lights should also be activated to alert passing vehicles and provide illumination. 2. In case of a breakdown or traffic accident on the road, the hazard lights should be turned on to alert other drivers to proceed with caution. On highways, if a vehicle breaks down or is involved in an accident and is parked without using the required lights or setting up warning signs, 12 points will be deducted from the driver's license. 3. When towing a disabled vehicle, both the towing vehicle and the towed vehicle should turn on the hazard warning lights to indicate that the vehicle is in an abnormal condition. 4. When making a temporary stop on the driving lane, turn on the hazard lights to alert other vehicles. 5. When forming a convoy as permitted by traffic authorities, all vehicles within the convoy should have their hazard lights on.

Will You Be Fined for Hanging Decorations on Car Rearview Mirrors?

Will you be fined for hanging decorations on car rearview mirrors? Installing small decorations on car rearview mirrors violates traffic regulations. Generally, no points will be deducted, but you may receive a warning and a fine of 50 yuan according to the relevant provisions of the Road Traffic Safety Law of the People's Republic of China. During emergency braking, hanging decorations inside the vehicle can easily fall and injure the driver or passengers, exacerbating their injuries. Therefore, according to Article 62 of the "Regulations for the Implementation of the Road Traffic Safety Law of China," driving a motor vehicle must not involve "hanging or placing items within the front and rear windows of the motor vehicle's cab that obstruct the driver's view."

What is the best tire for the Chevrolet Malibu?

For the Chevrolet Malibu, Goodyear tires are a good choice, with the tire specification being 225/55R17, which is a standard size. Here is some information about tires: 1. Tires are circular, elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are typically installed on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance. 2. Tires are often used under complex and demanding conditions. During driving, they endure various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance. 3. Tires need to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

Documents the seller needs to prepare: Original and photocopy of the original owner's ID card, original and photocopy of the vehicle's motor vehicle registration certificate, original and photocopy of the vehicle license, and the physical presence of the vehicle. Documents the buyer needs to prepare: Original ID card of the buyer, and for non-local residents needing license plates, a valid temporary residence permit or residence certificate. Vehicle ownership transfer: Vehicle ownership transfer refers to changing the name of the vehicle's owner. When a vehicle is transferred from one city to another, the registration process to change the vehicle's administrative authority is called re-registration. Vehicle re-registration requires changing the license plate and vehicle license, and the procedures must be completed at two different vehicle management authorities, including the transfer-out procedure and the transfer-in procedure.
