What does the six-year exemption from inspection for vehicles mean?

New vehicles exempt from inspection for six years means that the car does not need to undergo an on-site inspection at a vehicle inspection station for the first six years. The on-site inspection is only one part of the annual vehicle inspection, so the six-year exemption does not mean all inspections are waived for the first six years. The following are relevant details: 1. In fact, owners still need to undergo a periodic inspection every two years, submit relevant materials such as the compulsory traffic accident insurance certificate and vehicle and vessel tax, and obtain the annual inspection label. 2. Although new vehicles enjoy a six-year exemption from inspection, in reality, the vehicle must undergo an on-site inspection in the sixth year. During the first six years, in the second and fourth years, owners only need to complete some relevant formalities; however, in the sixth year, the owner must take the car to the inspection station for an on-site inspection, and only after passing the inspection can they obtain the inspection label. 3. Additionally, not all vehicles are eligible for the six-year exemption. The exemption policy only applies to non-operational mini and small passenger vehicles and non-operational cars (including large cars). Starting from November 20, 2020, non-operational small and mini passenger vehicles with 7-9 seats are also included.

What Causes Difficulty in Starting the Car but No Issues While Driving?

The reasons for difficulty in starting the car but no issues while driving are low car battery voltage; a malfunction in the fuel supply system; and insufficient spark plug ignition energy. Below is additional information: Specific manifestations: After turning the ignition switch, the engine, driven by the starter, runs for more than 5 seconds but still fails to start. The car battery is an essential part of the vehicle and can be categorized into traditional lead-acid batteries and maintenance-free batteries. Fuel supply system: The fuel supply system is a device used to supply combustible mixed gas. Due to differences in fuel types, the supply methods may vary. The spark plug, commonly known as the sparking plug, is a crucial component of the gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber and causes it to jump across the electrode gap to generate a spark, thereby igniting the combustible mixed gas in the cylinder. Components of a spark plug: A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded onto the shell.

How to Open the Hood of a Mercedes-Benz?

Method to open the hood of a Mercedes-Benz: 1. The hood release lever is located on the inner side of the driver's seat. 2. There is a small red lever above the clutch; pull this red lever. 3. Next to the front emblem, feel for a latch by hand from below and lift it upward to open the front hood. Functions of the hood: 1. Airflow guidance. 2. Protection for the engine and surrounding pipeline components. Beneath the hood are crucial parts of the car, including the engine, electrical circuits, fuel system, braking system, and transmission system, among others. 3. Aesthetics. The vehicle's exterior design is a direct reflection of its value, and the hood, as a significant part of the overall appearance, plays a vital role in enhancing visual appeal and embodying the concept of the entire car. 4. Assisting driving visibility. During driving, the shape of the hood helps effectively adjust the direction and form of reflected light, reducing the impact of glare on the driver. 5. Accident prevention. The engine operates in a high-temperature, high-pressure, and flammable environment, where overheating or accidental damage to components could lead to explosions, fires, or leaks. The hood serves as a protective shield, effectively blocking harm caused by such incidents.

What Low Temperatures Can an Average Car Withstand?

An average car can withstand temperatures as low as minus forty degrees Celsius. In the northern regions of China, winter climates are extremely cold, typically ranging from minus 5 degrees Celsius to minus 25 degrees Celsius, with the coldest periods seeing temperatures drop below minus forty degrees. Low temperatures can severely impact a car's operation, particularly during cold starts, leading to noticeable difficulties in ignition, severe wear on assemblies, increased fuel consumption rates, and exacerbated exhaust pollution. When temperatures fall below minus 18 degrees Celsius to minus 20 degrees Celsius, cold starts become quite challenging. If temperatures drop below minus forty degrees Celsius, a car cannot start at all without preheating. During use, a car's engine performance in low-temperature starts is mainly influenced by the viscosity of the lubricating oil, the vaporization properties of the fuel, and the working capacity of the battery. To mitigate the effects of low temperatures on car performance, it is necessary to warm up the car before use. However, the warming-up process does not require the car to remain stationary for an extended period. Instead, after starting the vehicle, allow the engine to run at a high idle speed automatically, and once the idle speed slightly decreases, the car can begin moving.

How Long Does It Generally Take for Car Paint to Dry?

After a car is painted, the paint can dry in two days during the summer when temperatures are higher. In winter, the drying time depends on the temperature and can take up to four to seven days. If the paint is baked, it can dry in two hours. For situations where the car is painted and picked up on the same day, it is recommended to wait two days before washing it. If the vehicle has sufficient ventilation and humidity, it can be washed after 6-7 hours. If the paint is dry, the car can be washed two days after the paint has dried. If the vehicle is painted in a paint booth, since it has already stayed in the booth for 3-4 hours, it can be washed immediately after being taken out. If the car has just been painted, be careful not to expose the freshly painted areas to water or dust. It's best not to drive the car out in rainy weather. The fresh paint is still delicate, and contact with rainwater can leave marks that may be difficult to remove, sometimes even impossible to polish out. It's advisable to park the car in a garage at night. As for sunlight, there's no need to worry—it only speeds up the drying process, which is beneficial.
