Is it necessary to change the license plate number when transferring a car?

When transferring a car, it is mandatory to change the license plate number. According to relevant regulations, while the vehicle can apply for transfer procedures, the license plate is not allowed to be transferred. During the vehicle transfer process, all previous traffic violations must be resolved, and the vehicle must pass inspection. If the vehicle is transferred for a second transaction, the license plate number must be changed, with the original number automatically retained by the system for 6 months. After completing the transfer registration or cancellation registration of a motor vehicle, the original owner can apply to use the original license plate number when registering the transfer, provided the following conditions are met: 1. The application must be submitted within one year after the transfer or cancellation registration; 2. The original owner must have owned the vehicle for more than one year; 3. All traffic violations and accidents involving the original vehicle must be resolved.

What is the lifespan of a catalytic converter in kilometers?

The domestic standard for the lifespan of a catalytic converter is approximately 80,000 to 100,000 kilometers of vehicle travel, while the international standard is generally 160,000 to 200,000 kilometers. The catalytic converter is the most important external purification device installed in the vehicle's exhaust system, converting harmful gases such as CO, HC, and NOx emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The primary mode of failure for catalytic converters is high-temperature deactivation: after the active components sinter at high temperatures, the Al2O3 in the coating transforms into Al2O3, which only causes the catalyst in the converter to fail without affecting the exhaust resistance. As a result, many vehicle owners may not notice the issue until emissions testing or vehicle inspection reveals it.

What are the time regulations for vehicle annual inspection?

Annual inspection time regulations: The first annual inspection for passenger cars is conducted when the vehicle reaches six years of age. For non-operational small and micro passenger vehicles, including family cars over 6 years but under 10 years old, an inspection is required every two years. For vehicles that have just reached six years, the owner must drive the vehicle to the inspection station with their ID card, vehicle license, vehicle and vessel tax or tax exemption certificate, and compulsory traffic insurance policy for vehicle testing. Upon passing the inspection, a certification form will be issued, which, along with the carried documents, should be presented at the relevant window to obtain the annual inspection sticker. The purpose of the annual inspection is to check: Whether the engine, chassis, body, and auxiliary equipment are clean, intact, and effective; whether the car's paint is symmetrical and aesthetically pleasing; whether major general components have been replaced and if they match the initial inspection records. Whether the vehicle's braking performance, turning maneuverability, lighting, exhaust pipes, and other safety factors comply with the requirements of the "Technical Conditions for Safe Operation of Motor Vehicles." Whether the vehicle has been modified, altered, or transformed; whether all records such as the vehicle license, license plate, and vehicle file match the current condition of the vehicle and if there have been any changes; and whether approval, alteration, or modification procedures have been applied for and completed. Whether the license plate printed on the vehicle, the vehicle license, and the enlarged characters on the license plate are damaged or illegible, and whether they need to be replaced.

How to Deal with Water Leakage in Car Doors?

Methods for handling water leakage in car doors: Open the door, fully lower the window, and use a small air gun to blow out the water. If the amount of water is significant, it is advisable to take the vehicle to a repair shop for maintenance. Water leakage in car doors can occur in two scenarios: while the vehicle is in motion or when it is parked. When water leaks while the vehicle is moving, there is a risk of water entering the engine if the water level reaches above 20 centimeters. This is because the engine's air intake pipe is positioned low, and the exhaust pipe's outlet is below the waterline, allowing rainwater to be sucked into the engine through the intake and exhaust openings during water immersion. When water leaks while the vehicle is parked, high external water levels can also lead to water damage to the battery and other electrical components of the vehicle.
