What Causes the Abnormal Noise When the Car Air Conditioner is Turned to Maximum?

Is it necessary to install an underbody guard for cars?

It is necessary to install an underbody guard for cars, and its functions are: 1. To protect engine components and various pipelines, preventing damage caused by contact and friction with the ground under harsh working conditions; 2. To improve the airflow field under the car, reduce wind resistance and wind noise, thereby improving fuel economy and the overall vibration and noise performance of the vehicle. The underbody guard is an engine protection device designed for various car models, preventing mud from covering the engine, extending the engine's service life, and avoiding car breakdowns caused by engine damage. The downside of the underbody guard: It hinders the protective sinking of the engine during a collision, weakening the protective effect of engine sinking.

Where to Check China 5 and China 6 Emission Standards for Vehicles?

You can find the China 5 and China 6 emission standards on the vehicle inspection sheet. The inspection sheet includes details such as the model, color, emission standard, engine number, and chassis number. The China 5 emission standard is marked with a 'V', while the China 6 emission standard is marked with a 'Ⅵ', both using Roman numerals. Typically, there is a nameplate under the front passenger door. Labels indicating the vehicle model can also be found in the lower left corner of the front windshield, on the driver's door pillar, on the left side of the dashboard, or in the engine compartment. For used cars, you can query the vehicle model on the environmental protection website using the following method: 1. Identify the vehicle model, which is usually indicated on the nameplate; 2. Visit the Motor Vehicle Environmental Protection Website, enter the vehicle model and verification code in the input box, then click 'Query' to proceed.

It is a consumable item in vehicle use. High-quality automotive windshield washer fluid mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Functions of windshield washer fluid: It is used to clean the windshield, maintain clear visibility, and has anti-freeze and anti-fog properties. It also has anti-static, lubricating, and anti-corrosion effects. It removes debris from the windshield, lowers the freezing point of the liquid, ensures the windshield remains clear and transparent, maintains clear visibility, eliminates static charges on the glass surface, reduces friction between the wiper and the glass, and prevents scratches.

What are the safety requirements for electric vehicle battery swapping?

Electric vehicle battery swapping safety requirements include safety specifications, testing methods, and inspection rules. Introduction to electric vehicles: Electric vehicles (BEVs) refer to vehicles powered by onboard power sources, using electric motors to drive the wheels, and meeting all requirements of road traffic and safety regulations. Due to their relatively smaller environmental impact compared to traditional vehicles, their prospects are widely optimistic. Compared to fuel-powered vehicles, the main differences of pure electric vehicles lie in four major components: the drive motor, speed controller, power battery, and onboard charger. Instead of gas stations, they utilize public ultra-fast charging stations. The quality differences of pure electric vehicles depend on these four components, and their value is also determined by the quality of these components. The applications of pure electric vehicles are directly related to the selection and configuration of these four components. Precautions for electric vehicle battery swapping: Visit authorized shops for battery replacement and pay attention to the date on the battery when swapping.

How many kilometers does a car need for maintenance?

Cars require maintenance at specific mileage intervals: The first maintenance for a new car should be performed at 5,000 kilometers or within one year, and the second maintenance should be at 10,000 kilometers or within one year after the first maintenance. Regular maintenance is required annually or every 10,000 kilometers driven, and different maintenance items are involved. Below is a partial introduction to car maintenance: 1. The first car maintenance requires changing the engine oil and oil filter, and checking the engine's working condition, such as whether all pipe connections are normal, whether there are any leaks, whether the engine sounds normal, and whether there are any abnormal noises. 2. The second car maintenance involves inspection and maintenance of dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.
