Is Automatic Transmission Difficult?

Where is the frame number of a small electric vehicle located?

Different brands of vehicles have different frame number locations. The frame number is generally located at the lower left corner of the windshield, on the right side of the passenger seat, or in the engine compartment. The engine number can usually be seen directly on the engine. In China, the frame number typically consists of 17 digits and letters, each with the following meanings: 1. Positions 1-3 (WMI): World Manufacturer Identifier, indicating the manufacturer. 2. Positions 4-6: Vehicle type, configuration of the model, and body code. 3. Positions 7-9: Engine type code; type of transmission. 4. Check digit: The check digit is usually represented by a number from 0-9 or the letter 'X'.

What to Do When a Tire Scrapes Against the Curb?

After a tire scrapes against the curb, the first step is to check the tire surface for any damage or air leakage. If the tire is visibly blackened from scraping the curb, it is recommended to move it to the rear wheel to prevent potential safety hazards. Effects of scraping the curb: 1. Tire damage: Scraping the curb can severely damage the tire. It may cause bulging on the tire sidewall, deform the wheel rim, or even lead to deformation of the chassis suspension or shock absorbers. 2. Underbody damage: When parallel parking, operate carefully. Descend the curb one wheel at a time while using the brakes to control the vehicle to avoid underbody damage. If unsure about positioning, slow down and avoid forcing the vehicle onto the curb.

Can a Vehicle That Hasn't Passed Annual Inspection Be Transferred?

A vehicle that hasn't passed the annual inspection cannot undergo the transfer procedure. According to regulations, before transferring a vehicle, all traffic violations and accident records related to the vehicle must be resolved. Only vehicles that have passed the annual inspection are eligible for transfer. If the vehicle has exceeded its inspection validity period, the owner must submit the vehicle's safety technical inspection certificate and compulsory traffic accident liability insurance certificate. "Motor Vehicle Registration Regulations": Article 19 states that when applying for transfer registration, the current owner of the motor vehicle must fill out an application form, present the vehicle for inspection, and submit the following documents and certificates: Proof of identity of the current motor vehicle owner. Documents and certificates proving the transfer of motor vehicle ownership; motor vehicle registration certificate. Motor vehicle driving license. For motor vehicles under customs supervision, the "Release Certificate for Customs Supervised Vehicles of the People's Republic of China" or a customs-approved transfer certificate must also be submitted. For motor vehicles that have exceeded their inspection validity period, the vehicle's safety technical inspection certificate and compulsory traffic accident liability insurance certificate must also be submitted.

Why is the car air conditioning cooling slower?

There are several reasons why car air conditioning cools slower: 1. Insufficient refrigerant due to low refrigerant levels: The main cause of insufficient refrigerant is usually minor leaks in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease. As a result, when the refrigerant evaporates in the evaporator, the amount of heat absorbed will decrease, leading to reduced cooling capacity. 2. Moisture infiltration in the air conditioning refrigeration system causing insufficient cooling: There is a component in the refrigeration system called the dryer (or receiver-drier), one of its main functions is to absorb moisture from the refrigerant to prevent excessive moisture in the refrigerant from reducing cooling capacity.

Which Came First: Cars or Traffic Lights?

Traffic lights were invented 17 years earlier than cars. Initially, traffic lights were created for the passage of horse-drawn carriages and had nothing to do with automobiles. History of Traffic Lights: 1. Early Form: In 1858, gas-powered red and blue mechanical lever-operated signal lights were installed on major streets in London, England, to direct horse-drawn carriage traffic. These were the world's earliest traffic signals. In 1868, British mechanical engineer J.P. Knight installed the world's first gas-powered traffic lights in front of the Houses of Parliament in Westminster, London. They consisted of rotating square glass lanterns in red and green, with red indicating 'stop' and green indicating 'caution'. 2. Electric Traffic Lights: In 1914, electrically operated traffic lights appeared in the United States. These lights featured red, green, and yellow circular projectors and were mounted on a tower at Fifth Avenue in New York City. A red light meant 'stop', and a green light meant 'go'. 3. Official Use: In 1968, the United Nations 'Convention on Road Traffic and Road Signs and Signals' standardized the meanings of various traffic lights. The introduction of traffic lights enabled effective traffic control, significantly improving traffic flow, road capacity, and reducing accidents.

Is Crystal Coating Necessary for New Cars?

New cars do not require crystal coating. The original paint of a new car already has excellent gloss, and the high cost of crystal coating makes it an unnecessary expense. Advantages of crystal coating: 1. Scratch resistance: Diamond crystal hardness reaches 6H, compared to the 2H hardness of ordinary car paint, it can prevent most minor scratches. It also has an elastic recovery function, protecting the vehicle from daily minor scratches and reducing paint scratches by more than 70% compared to ordinary coatings. When external force exceeds the elastic protection range of the crystal, it usually only leaves scratches on the crystal without damaging the paint. 2. Corrosion resistance: The ultra-fine nano-crystal layer of diamond crystal isolates the paint from the external environment, effectively preventing oxidation. It resists corrosion from bird droppings, insect residues, acid rain, etc. 3. No cracking: Diamond crystal resists UV rays, high temperatures, and extreme cold. With a temperature resistance range of -50°C to 300°C, it adapts to wide temperature changes without cracking or peeling. 4. Easy cleaning: The strong fiber network of diamond crystal fills the invisible fine pores of the car's paint surface, achieving a mirror-like finish that makes the car easy to clean and maintain. Various dust and dirt can be rinsed off with just water, restoring and maintaining the car's surface to a sparkling clean state. Even if oil stains or insect remains are present, they can be easily removed by wiping the surface with a wet towel, reducing car washing frequency by more than 50%. It also has excellent hydrophobic self-cleaning properties.
