What is the working principle of a differential?

The working principle of a differential is: 1. Power input to the differential, where the driven bevel gear drives the rotation of the differential housing; 2. Power output from the differential, where two side gears are connected to the drive shafts (also known as half-shafts) on both sides, transmitting power to the wheels; 3. The rotation of the planetary gears refers to the rotation of the planetary gears around the planetary gear shaft; 4. The revolution of the planetary gears refers to the rotation of the planetary gears around the axis of the side gears. The automotive differential is a mechanism that allows the left and right (or front and rear) drive wheels to rotate at different speeds. It mainly consists of left and right side gears, two planetary gears, and a gear carrier. Its function is to enable the left and right wheels to roll at different speeds when the car is turning or driving on uneven roads, ensuring that both drive wheels perform pure rolling motion. The differential is designed to adjust the speed difference between the left and right wheels.

What procedures are required for vehicle color change registration?

Procedures required for vehicle color change registration are as follows: Required documents: Color change application, vehicle model information, motor vehicle registration certificate, vehicle license, original and copy of owner's ID card. Clear all fines before color change. Since the registration procedure for changing vehicle color involves modifying original registration records and replacing the original vehicle license, it is equivalent to going through new vehicle registration again. Vehicles eligible for color change: Not all vehicles are allowed to change color. Only domestically produced vehicles are permitted, while imported vehicles are prohibited from color changes. The repainted color must not be identical to special service vehicle colors, and no exterior modifications or accessories may be added. Importantly, the color change must be performed at a qualified automotive beauty and repair enterprise with national certification to pass inspection.

Can headlights with black film pass the annual inspection?

Headlights with black film cannot pass the annual inspection. Any modification that makes the vehicle appearance inconsistent with the information on the vehicle registration certificate will have an impact. Relevant regulations: According to the current "Motor Vehicle Registration Regulations," any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, including replacing the frame, body, or engine, require the owner to apply for modification registration with the vehicle management office. Installing spoilers, body kits, or modifying exhaust pipes are generally not allowed. Traffic regulation penalties: Unauthorized changes to the motor vehicle's appearance or registered technical data will result in the traffic management authorities ordering the restoration of the original condition and issuing a warning or fine. Applying blue film to headlights or smoked film to taillights constitutes altering the vehicle's appearance. The traffic management authorities (traffic police) will order the restoration of the original condition and impose a fine.

Can the car's charcoal canister be replaced?

Yes, the car's charcoal canister can be replaced. Replacement cycle for the charcoal canister: In fact, there is no fixed replacement cycle for the car's charcoal canister, and the vehicle's user manual does not specify how often the charcoal canister should be replaced. As a car owner, there is no need to replace the charcoal canister as long as it is not damaged. Some 4S shops may recommend replacing the charcoal canister every 40,000 to 60,000 kilometers, but this is only a conservative estimate of the canister's lifespan. Function of the charcoal canister: The activated charcoal canister is usually installed between the fuel tank and the engine. It utilizes the adsorption capacity of the internal activated charcoal to adsorb and store fuel vapors from the fuel tank. When the engine starts, the solenoid valve between the activated charcoal canister and the intake manifold opens according to the ECU's command. At this time, the fuel vapors in the activated charcoal canister are drawn into the cylinder along with the air under the vacuum pressure of the intake pipe to participate in combustion. This not only reduces unnecessary emissions but also lowers the engine's fuel consumption.

Will the touch-up paint on a new car show differences after a few years?

Will the touch-up paint on a new car show differences after a few years. Reasons why it can't match the original paint: After a car is repainted, it cannot achieve the same effect as the original. The factory-applied paint is high-temperature paint with excellent hardness because the car body is empty during baking, allowing temperatures to reach several hundred degrees. During touch-up painting, the car body has many components and equipment, making high temperatures impossible—only around 50 degrees Celsius—so the paint hardness cannot match the original. Layers of car paint: The paint applied on the automotive production line consists of four layers: the electrophoretic layer, primer layer, base coat layer, and clear coat layer. The electrophoretic layer is the "foundation," directly adhered to the metal car body, serving as anti-corrosion. The primer layer is applied over the electrophoretic layer. During application, the entire car body frame is fully immersed in a large pool filled with paint; the primer layer protects the electrophoretic layer and enhances corrosion resistance.

Are Chassis Bolts Important?

Chassis bolts are very important. Safety Hazards: Loose bolts can pose significant safety risks without the owner's awareness. Therefore, car owners must pay attention to the inspection of automotive screws, especially those on the chassis. Inspection Cycle: The chassis endures substantial vibrations, so the screws on the chassis are specially treated by manufacturers, with enhancements in steel quality, hardness, and shock resistance. Generally, screws won't come loose unless the vehicle is of very poor quality, so there's no need to worry excessively. The recommended frequency for inspecting automotive screws is every one to two years during a maintenance visit to a 4S shop.

Can You Turn on the Air Conditioner Directly After Starting the Car in Summer?

You should not turn on the air conditioner directly after starting the car in summer. Using the air conditioner in summer: When the external temperature rises above 35 degrees Celsius, the interior of a closed car can reach 65 degrees within 15 minutes, causing the emission of formaldehyde, benzene, toluene, xylene, etc., to be 5 to 7 times higher than normal. When you first get into the car, open the windows for ventilation for one to two minutes to allow the toxic air to dissipate before driving and turning on the air conditioner. Turning off the air conditioner in advance: Before reaching your destination, turn off the air conditioner in advance and keep the fan running. This not only helps avoid forgetting to turn off the air conditioner and starting the engine with it still running but also keeps the air vents dry, preventing moisture and bacterial growth.
