How are car classes categorized?

Cars are primarily classified based on parameters such as wheelbase and vehicle length. The main car classes include subcompact cars, compact cars, midsize cars, and full-size cars. Dimensions for each car class: Subcompact cars: Wheelbase ranges between 2350mm to 2600mm, with body length between 3700mm to 4450mm. Compact cars: Wheelbase ranges from 2500mm to 2750mm, with body length between 4300mm to 4750mm. Compact cars are the preferred choice for family vehicles as they meet daily commuting needs while maintaining reasonable usage costs, making them the mainstream models in the domestic market. Midsize cars: Wheelbase ranges from 2650mm to 2950mm, with body length between 4600mm to 5000mm. Midsize cars are commonly used for business purposes in China. Full-size cars: Wheelbase exceeds 2900mm, with body length over 5100mm.

How to Deal with Fogging on the Outside of Car Windows on Rainy Days?

When car windows fog up on rainy days, the following methods can be used to address the issue: 1. Preventive measures such as applying anti-fog spray. Spray a small amount of anti-fogging agent on the car windows and wipe it clean to remove dirt and stains from the glass. 2. Air conditioning cooling method. Utilize the air conditioning's dehumidification function to reduce air humidity and eliminate fog. 3. Air conditioning heating method. Use the method of reducing the temperature difference to remove condensation. Fogging on car windows during rain occurs under two conditions: high humidity and low temperature. When the air humidity is at a certain level and the window temperature falls below the dew point, condensation forms on the window surface, which is the fogging phenomenon we often see on the windshield. Additionally, when there is a certain temperature difference between the two sides of the window, and the saturated vapor pressure of the surface moisture on the cooler side is lower than the surrounding environment's vapor pressure, moisture gathers on the glass surface, forming tiny droplets that appear as fog. If the dew point is above zero degrees Celsius, fogging occurs; if it is below zero degrees Celsius, frost forms.

Which car insurances are generally purchased?

Apart from compulsory traffic insurance which is mandatory, other car insurances are optional. Here are the specific introductions of car insurances: 1. Compulsory Traffic Insurance: This is a legally required insurance that every car owner must purchase. It provides the most basic insurance claims when traffic accidents occur. In the event of an accident, compulsory traffic insurance can help car owners cover difficult-to-pay economic compensations. The compensation amount is determined based on the car owner's liability proportion in the accident and whether it causes casualties. 2. Vehicle Damage Insurance: This insurance covers damages to the insured vehicle caused by accidents when driven by the insured or an authorized driver. The insurance company will provide reasonable compensation. The premium for vehicle damage insurance is closely related to the vehicle's purchase price and the number of seats. 3. Third-party Liability Insurance: This insurance covers compensation for bodily injuries or direct property damages to third parties (excluding the driver and passengers of the insured vehicle) caused in an accident. The insurance company will compensate according to regulations.

What to Do If Engine Oil Is Insufficient?

When the engine oil is insufficient, the engine's cooling and heat dissipation capacity will decrease, causing the engine to overheat internally, which can further lead to phenomena such as bearing bush ablation and cylinder scoring. During driving, symptoms like insufficient power and excessive oil consumption can be felt. Consequences of Insufficient Oil: It can cause friction between various internal components of the engine, resulting in poor surface lubrication. If the engine lubrication is inadequate, it will exacerbate the wear and tear of the parts. Solutions for Insufficient Oil: When it is found that the oil level is too low, try to find a nearby repair shop or gas station to replenish the oil as soon as possible. Remember to use the same type of oil as the original oil and avoid mixing it with other oils, as this can alter the oil's performance, such as reducing its lubrication and cooling properties, making it unable to better protect the engine. Consequences of Excessive Oil: The oil level should not be too high either; the oil level must not exceed the upper limit on the dipstick. Otherwise, it can easily increase the engine load, affecting performance. Over time, the engine's exhaust ventilation system is also prone to damage, increasing carbon deposits. Excessive oil can also lead to oil burning.

How to Handle Motor Vehicle Scrapping?

Vehicle scrapping process: The car owner applying for scrapping and renewal should fill out the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form" in duplicate and affix the owner's seal. Apply at the registration acceptance counter. For vehicles that have reached the scrapping age limit, a "Vehicle Scrapping Notice" will be issued. For vehicles that have not reached the scrapping age limit, after inspection and confirmation by the motor vehicle inspection counter that they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner should choose a qualified recycling company to send the vehicle for dismantling, based on the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner should submit the "Change Form", "XX Province Renewal Vehicle Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the motor vehicle inspection counter for verification and signature. The license plates and certificates will be reclaimed, and the application will be submitted for approval according to regulations to complete the scrapping registration.

What does the letter V on car tires represent?

V represents the speed rating of the tire, with a maximum speed of 240 kilometers per hour. The speed rating indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h for tires. Common speed ratings are as follows: 1. Q represents 160 km/h, R represents 170 km/h, S represents 180 km/h; 2. T represents 190 km/h, H represents 210 km/h, V represents 240 km/h; 3. W represents 270 km/h, Y represents 300 km/h, Z represents speeds above 240 km/h.
