What are the effects on a car if it doesn't slow down when passing speed bumps?

Frequently passing speed bumps without slowing down can affect the car's suspension, wheels, and interior components. Car Suspension: When a vehicle passes over a speed bump, there is a noticeable impact and a barely perceptible deceleration. Although speed bumps are not completely vertical, they always have some angle. When passing over this angle, the speed bump exerts resistance on the tires, which is directly transmitted to the suspension and then to the car body, resulting in a complete impact. Wheels: This primarily affects mid-to-high-end cars equipped with large-sized wheels and wide, low-profile tires. The sidewall thickness of the tires serves as the first level of shock absorption for the car. The greater the thickness, the more compression it can absorb. If the car doesn't slow down when passing a speed bump, the momentary state is that the tire gets flattened, then hits the wheel rim, and finally returns to the road surface. Each instance of such driving will impact the wheel rim, and over time, it will naturally cause damage to the wheels. Interior Components: This includes electronic configurations, interior panels, CD players, car audio systems, and other visible components. Upon closer inspection, these are all fixed with screws or clips. Frequently passing speed bumps without slowing down can cause rattling noises in the interior components.

Why Shouldn't You Buy a Flood-Damaged Car?

Flood-damaged cars should not be purchased for the following reasons: 1. Electronic system malfunctions: The most water-sensitive components in a car are the electronic systems. Although modern vehicles have waterproofing for electronic circuits, they cannot withstand heavy or prolonged water exposure. If water submerges the engine compartment for an extended period, it can cause wiring corrosion and short circuits, leading to electronic function failures or even spontaneous combustion. 2. Engine failure: Generally, if water has submerged the engine compartment, do not attempt to start the car, as there's no guarantee that the engine hasn't taken in water. Starting it directly could result in immediate engine failure. 3. Transmission issues: The depreciation of flood-damaged cars often stems from transmission problems. Transmissions have vents to release pressure from temperature changes, typically located on the upper part. If water levels rise too high and flood the engine compartment, water may enter the transmission. This can cause slipping, shaking, gear shift jerking, or even necessitate major transmission repairs. 4. Interior mold: Rainwater contains numerous impurities, and a flooded car interior becomes an extremely humid environment prone to mold growth. If the vehicle isn't dried promptly, mold can ruin fabric and leather surfaces while creating unpleasant odors.

What is the purpose of the central locking system in a car?

Central locking system functions are as follows: 1. Central control. When the driver locks the door next to them, all other doors are simultaneously locked. The driver can unlock all doors at once using the door lock switch or open a specific door individually. 2. Speed control. When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening doors by operating the door handles. 3. Individual control. In addition to the driver's door, other doors are equipped with separate spring lock switches that can independently control the opening and locking of individual doors.

What Materials Are Used in Brake Pads?

Here is a detailed introduction to the materials used in brake pads: 1. Semi-metallic materials. These brake pads are still the mainstream products in the market, offering affordable prices and excellent braking performance. However, their shortcomings are also quite evident, including a tendency to generate noise, significant wear on brake discs, and the tendency for brake dust to adhere to the wheel hubs, affecting the wheel's appearance. 2. Ceramic materials. Composed of mineral fibers, glass fibers, and copper elements, ceramic brake pads feature high-temperature resistance, slow thermal decay, no noise, superior braking performance, low wear rates on brake discs, minimal brake dust, and easy cleanup. The downside is their relatively higher price and lower wear resistance compared to metallic brake pads.

What is the classification code for automobile repair invoices?

The automobile repair industry falls under the category of repair and maintenance services in the tax classification code, with the code number 202000. Rules for the classification code of ordinary invoices: The classification code for ordinary invoices (hereinafter referred to as the classification code) consists of 12 Arabic numerals: The first digit represents the code for the State Taxation Bureau or the Local Taxation Bureau, where 1 stands for the State Taxation Bureau, 2 for the Local Taxation Bureau, and 0 for the General Administration; the 2nd, 3rd, 4th, and 5th digits are the regional code (prefecture or city level), based on the unified national administrative region code, with the General Administration being 0000; the 6th and 7th digits are the year code (for example, 2004 is represented as 04); the 8th digit is the unified industry code; the 9th, 10th, 11th, and 12th digits are the refined invoice type codes, which are independently compiled by the State Taxation Bureaus and Local Taxation Bureaus of provinces, autonomous regions, municipalities directly under the central government, and cities specifically designated in the state plan, following the principle of ensuring the uniqueness of each invoice code. Rules for the invoice number: The ordinary invoice number consists of 8 Arabic numerals. If the invoice number resources are insufficient, consideration should be given to combining with the classification code during design, i.e., setting one digit in the 9th, 10th, 11th, or 12th position of the classification code as a batch code; for enterprise-named invoices, one digit can be set separately in the 9th, 10th, 11th, or 12th position of the classification code, or directly in the invoice number by allocating a range of numbers to each enterprise for compilation.

How to Use the Auto-Folding Feature of Changan's Rearview Mirrors

The method to auto-fold Changan's rearview mirrors is as follows: Rotate the knob to the exterior mirror folding button, and the exterior mirrors will automatically fold. When the knob is rotated away from this position, the exterior mirrors will automatically unfold simultaneously. If manual folding is required for mirrors with electric folding functionality, please operate when the mirrors are stationary. Otherwise, it may cause the mirrors to fail to reset, become loose, or even damage the components. If the mirrors cannot reset or become loose, try activating the electric folding function to restore them. Additional note: The folding feature of rearview mirrors is an excellent function that offers certain benefits during vehicle use. However, it is important to note that the folding feature should be turned off in winter due to rain, snow, and weather conditions. Once freezing occurs, it can cause the mirrors to freeze, and using the folding function may damage the folding motor.
