Vehicle identification number, fully known as Vehicle Identification Number, consists of 17 characters, so it is commonly called the seventeen-digit code. It contains information such as the vehicle's manufacturer, year, model, body type and code, engine code, and assembly location. The details about the vehicle identification number are as follows: 1. Body type: Refers to the general structure or shape of the vehicle, such as the number of doors and windows, the characteristics of the cargo being transported, and the type of roof (such as van body, fastback body, hatchback body), which distinguishes the vehicle. 2. Engine type: Refers to the characteristics of the power unit, such as the fuel used, number of cylinders, displacement, and static braking power. Engines installed in passenger cars, multi-purpose passenger vehicles, or trucks with a gross vehicle weight rating of 10,000 lb or less should indicate the professional manufacturer and model. Kind: The manufacturer's designation for all vehicles within the same brand that share certain structural similarities, such as body, chassis, or cab type. 3. Make: The name given by the manufacturer to a group of vehicles or engines. Model: Refers to the name given by the manufacturer to vehicles that share the same type, make, kind, series, and body type. 4. Model year indicates a specific model year, and as long as the actual cycle does not exceed two legislative years, the actual production year of the vehicle can be disregarded.

The Vehicle Identification Number, commonly known as the VIN, is the unique ID for every car, consisting of 17 alphanumeric characters. I always emphasize its importance when helping friends buy or sell used cars, as it helps prevent purchasing accident-damaged or cloned vehicles. By checking its history on various websites like Carfax, you can easily see the number of accidents, repair conditions, and recall information of the vehicle. I always perform this step before buying a car myself, saving a lot of unnecessary trouble. During insurance claims, companies also verify the VIN to confirm the vehicle's identity, avoiding fraudulent claims. In short, it's a small detail but crucial for safety—never overlook the VIN found in the lower left corner of the windshield or on the door pillar. In daily use, it’s both simple and practical.

Which Car Modifications Are Legal?

Here is a detailed introduction to the scope of legal car modifications: 1. Vehicle Appearance: Modifications include changing the body color or applying body wraps. The vehicle must be registered with the vehicle management office within 10 days after the color change, with new license photos taken and the vehicle license updated. However, the following colors are prohibited: fire engine red (R03 bright red), administrative law enforcement vehicle colors (white top with blue bottom), and engineering rescue yellow. 2. Bumpers: Front and rear bumpers are crucial, but modifications must not alter the vehicle's length or width. 3. Wheels: When modifying wheels, the rim size must remain unchanged, as altering it affects the car's power and performance and is illegal. However, rims of the same size can be replaced. 4. Interior: Modifications are allowed as long as they do not compromise driving safety. However, seats cannot be removed or added without authorization, and the structural characteristics registered with the vehicle management office must not be altered. 5. Roof Rack: Passenger cars can install roof racks no taller than 30cm. 6. Engine: If the engine is damaged or has quality issues, proof from a certified repair shop and the source of the replacement engine can be submitted for modification approval, but the engine model must remain unchanged.

Buy a Car or a Parking Space First?

If conditions permit, purchasing a parking space first is advisable. From an investment perspective, unless you urgently need a car, buying a parking space generally takes precedence over buying a car. Here are the reasons for prioritizing a parking space: 1. Parking scarcity: Like housing, parking spaces occupy land resources. With the continuous improvement in living standards, the number of private cars is bound to increase steadily. Consequently, parking spaces will become increasingly scarce in the future. Currently, parking difficulties are already widespread. 2. High appreciation potential: Financial experts have pointed out that residential parking spaces are one of the investment projects with significant appreciation potential in the future. This prediction has unfortunately come true, with appreciation rates already surpassing those of the real estate market, and the momentum remains strong. Moreover, for car owners, parking spaces are no longer just investment products but daily necessities. 3. High parking fees: Currently, renting a parking space is still an option. However, with rising parking fees and an increasing number of vehicles in residential areas, there is no guarantee that parking space owners will have extra spots available. Comparatively, the main appeal of renting a parking space is the lower short-term costs, but in the long run, it is not as cost-effective as buying one.

What to Do When the Passenger Door Cannot Be Opened from Inside or Outside?

If the passenger door cannot be opened from inside or outside, it can be sent to a repair shop for servicing. Below is an explanation regarding car doors: 1. Definition: Provides access for the driver and passengers to enter and exit the vehicle, isolates external disturbances, and to some extent mitigates side impacts to protect the occupants. 2. Inspection: For new car door inspections, first observe whether there are small ripples on the door frame, then check if there are any issues with the A-pillar, B-pillar, or C-pillar of the new car, and also inspect whether there is rust on the edges of the door frame. 3. Function: The aesthetics of the car are also related to the design of the doors. The quality of the doors is mainly reflected in their anti-collision performance, sealing performance, ease of opening and closing, and of course, other functional indicators.

What does 5W mean in motor oil?

The meaning of 5W in motor oil is that 5W is just a temperature grade, representing the minimum applicable temperature of the oil. Below this temperature, the oil becomes very viscous and loses its normal flow capability. The number 5 indicates that the minimum applicable temperature of the oil is -30 degrees Celsius. For example, in the winter outdoors in northern China, if the temperature drops below -30 degrees Celsius, using 5W oil after the vehicle has been parked for a long time can be very troublesome. Oil viscosity specifications: In fact, there are many types of viscosity specifications. Different types of oil have their own characteristics. Taking 5W30 oil as a reference, the letter "W" stands for Winter, while the "5" represents the cold-start performance of the oil. The smaller the number, the stronger the oil's cold resistance, allowing the engine to start easily even at very low temperatures. The last number "30" represents the kinematic viscosity standard at 100 degrees Celsius (between 9.3mm2/s and 12.5mm2/s). Oil classification: High-temperature types for summer use include 20, 30, 40, and 50. The larger the number, the higher the viscosity and the maximum applicable temperature. Low-temperature types for winter use include 0W, 5W, 10W, 15W, 20W, and 25W. The symbol "W" stands for Winter, and the smaller the number before "W," the lower the low-temperature viscosity and the better the low-temperature flow performance, meaning it can be used at lower minimum temperatures. All-season types suitable for both winter and summer include 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, and 10W-50, among others. The smaller the number before "W," the lower the minimum applicable temperature of the oil, and the larger the number after the hyphen, the higher the maximum applicable temperature.

What are the reasons for body shaking and engine warning light coming on?

The reasons for body shaking and engine warning light coming on are as follows: 1. Carbon deposits on valves and intake passages: When severe carbon deposits form on the intake and exhaust valves and intake passages, the fuel injected by manifold injection engines can be partially absorbed by the carbon deposits. This results in a discrepancy between the actual fuel entering the cylinder and the amount preset by the ECU. The energy released after combustion of the mixture cannot meet the power demand, leading to shaking. 2. Deviation in cylinder conditions: When the gap between the cylinder liner and piston increases, high-temperature gases can easily leak through the gap during cold starts due to insufficient oil lubrication, reducing power output. 3. Malfunction of the water temperature sensor: The water temperature sensor is one of the important bases for the computer to determine the engine's operating conditions. If the engine's cold start temperature is -10°C, but the sensor "tells" the computer "the current temperature is 10°C," the computer will inject fuel based on the 10°C condition, resulting in insufficient fuel and shaking. 4. Unstable oil pressure: Abnormal fuel pump supply pressure or incorrect and poor performance of the intake pressure sensor can cause body shaking. 5. Fuel quality issues: When the fuel does not meet the standard, combustion cannot achieve the corresponding heat value, resulting in lower power output. In addition, incorrect fuel grade or poor fuel quality can also cause engine shaking.
