What to Do After a Hit-and-Run Accident?

How to Check the Emission Standard of a Car?

To check the emission standard of a car, you can follow these methods: 1. Take the vehicle registration certificate to the vehicle management office and ask the staff at the corresponding window to check it for you; 2. Log in to the Motor Vehicle Environmental Protection Website, enter the required information as prompted, and click the query button; 3. For new cars, you can check the emission standard on the vehicle's factory certificate or the vehicle conformity certificate. The automobile emission standard refers to the regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and carbon smoke emitted from automobile exhaust. To curb the production of these harmful gases and encourage automobile manufacturers to improve their products to reduce the source of these harmful gases, both Europe and the United States have formulated relevant automobile emission standards. These standards are continuously supplemented, refined, and tightened with the increase in car ownership and the deterioration of the environment.

How Often Should the Clutch Disc Be Replaced?

The clutch disc should be replaced every 100,000 kilometers. Replacement is necessary under the following circumstances: 1. The clutch pedal feels higher; 2. The vehicle lacks power during acceleration or climbing, even when the engine shows no abnormalities; 3. Delayed response when rapidly accelerating to overtake at high speeds; 4. Severe shaking during startup, especially when the clutch is partially engaged. The clutch disc is a composite material primarily designed for friction, while also meeting structural performance requirements. Automotive friction materials are mainly used to manufacture brake pads and clutch discs. Traditionally, asbestos-based friction materials were predominantly used. However, with increasing environmental and safety standards, semi-metallic friction materials, composite fiber friction materials, and ceramic fiber friction materials have gradually emerged.

How to Remove Spray Paint from a Car?

The method to remove spray paint from a car is: 1. Apply some solutions that can dilute paint, such as banana oil, cooling oil, or olive oil, evenly on the area with spray paint; 2. Wait a few minutes for the solution to fully penetrate, then wash it off with soap or car wash liquid; 3. Use a white towel to wipe it clean, as a colored towel may cause fading. Spray paint is usually composed of an aerosol can, aerosol valve, contents, and propellant. It is a type of paint that has been specially treated and pressurized for easy spraying. Spray paint can be categorized into several types based on the main film-forming substances, including nitro-based aerosol paint, alkyd-based aerosol paint, and thermoplastic acrylic aerosol paint.

Will the Dash Cam Delete Footage Automatically?

Dash cams do delete footage automatically, typically through an auto-loop recording feature. Videos captured in emergency recording mode are automatically locked to prevent overwriting by other footage, ensuring better protection of critical recordings in case of accidents. Dash cams can also be used at home as DVs to capture life's moments or serve as home surveillance devices, while also functioning as parking monitors. A dash cam is an instrument that records images, sounds, and related data during vehicle operation. Once installed, it documents the entire driving process in video and audio, providing crucial evidence for traffic accidents.

What to Do If the Vehicle Inspection Sticker Is Lost?

If the vehicle inspection sticker is lost, the solution is to apply for a replacement promptly. You need to bring the vehicle's registration certificate and the owner's ID card to the vehicle management office in the city where the vehicle is registered to fill out a replacement application form. After approval, a new annual inspection sticker will be reprinted. Vehicle inspection precautions: 1. Check if the vehicle has any traffic violations; 2. Confirm whether the insurance is still valid; 3. Check the triangular warning sign inside the vehicle. Vehicle inspection refers to a mandatory test for every vehicle that has obtained an official license plate and registration certificate, equivalent to an annual physical examination for the vehicle according to the safety technical conditions for motor vehicle operation. Vehicle inspections can promptly eliminate potential safety hazards, encourage better vehicle maintenance, and reduce the occurrence of traffic accidents.

How often should the gear oil in a sedan be changed?

Sedan gear oil should be changed every 60,000 to 80,000 kilometers. In small passenger vehicles, gear oil is also referred to as manual transmission fluid, as the internal components of a manual transmission rely on gears for power transfer, and the lubricant provides lubrication for these gears. Gear oil is a high-viscosity lubricant specifically designed to protect power transmission components, typically characterized by a strong sulfur odor. The primary requirement for gear oil is to form a continuous and resilient oil film on the contact surfaces between gears, meaning it must possess high oiliness to maintain a tough boundary oil layer between transmission components. Additionally, gear oil should have excellent viscosity-temperature properties to minimize friction losses in the power transmission mechanism and enhance transmission efficiency.
