What does 3C car mean?

Automotive 3C refers to the 3C certification, which is the abbreviation of the English name "China Compulsory Certification" (China's compulsory product certification system). It is a product conformity assessment system implemented by the Chinese government to protect consumer personal safety and national security, strengthen product quality management, and comply with laws and regulations. The following is an introduction to the 3C mark: 1. The 3C mark is usually affixed to the surface of the product or molded onto the product. 2. The currently designed CCC mark not only has laser anti-counterfeiting features but also includes a unique serial number for each model, with no duplicate numbers. 3. The method for consumers to distinguish between genuine and fake CCC marks is very simple. Upon closer inspection of the CCC mark, multiple small diamond-shaped "CCC" hidden marks can be found. Additionally, the aspect of the CCC mark that is difficult to counterfeit is that each mark has a random code on the back, which indicates the manufacturer and product corresponding to each random code. Based on the random code, the authenticity of the product's origin can be verified.

What is the difference between 5W-30 and 5W-40?

The main difference between 5W-30 and 5W-40 lies in their viscosity. The number following the 'W' indicates the kinematic viscosity of the oil at 100°C. A higher number means the oil has higher viscosity, so 5W-30 oil has slightly lower viscosity than 5W-40. Additionally, their stability at high temperatures differs. 5W-40 offers better high-temperature stability compared to 5W-30. W stands for 'winter,' and the smaller the number before it, the better the oil's low-temperature fluidity. This means the oil can be used in lower environmental temperatures and provides better engine protection during cold starts. The number before the W represents the freezing point: 0W is -35°C, 5W is -30°C, 10W is -25°C, 15W is -20°C, 20W is -15°C, and 25W is -10°C. The number after the W indicates the oil's kinematic viscosity at 100°C. A higher number means higher viscosity and better protection at high temperatures. It can also be understood as representing the oil's stability at high temperatures (i.e., its resistance to thinning). A larger number indicates better high-temperature stability. 5W-30 oil is less viscous than 5W-40, making it more suitable for new engines and vehicles. 5W-40 oil has higher viscosity, making it more suitable for older vehicles as it enhances sealing and helps prevent oil consumption. However, in practice, the difference between the two is minimal. Both 5W-30 and 5W-40 have a wide temperature range and are considered all-season oils, providing good fluidity for cold starts and a thicker oil film at high temperatures for better engine protection. Under the high-speed, high-temperature, and high-pressure conditions of engine operation, oil needs to be replaced regularly. The replacement interval varies depending on the oil quality. After reaching the replacement interval, the vehicle can still be used, but the oil should be replaced as soon as possible. Typically, fully synthetic oil should be replaced every 8,000 to 10,000 kilometers. During the warranty period required by the vehicle manufacturer, failure to perform timely maintenance may result in engine issues and affect the vehicle's warranty. Expired oil can negatively impact engine performance. Over time, oil can oxidize and absorb moisture, leading to degradation and reduced performance. To ensure timely oil changes, many manufacturers now include maintenance reminder lights or notifications in their vehicles. These alerts inform the owner when it's time to replace the oil and oil filter based on mileage or time intervals.

Will running over the white line when going straight on a green light be captured?

Running over a solid white line when going straight on a green light can be captured by cameras, resulting in fines or penalty points. Solid white lines must not be crossed, but crossing dashed white lines is not considered a violation. In fact, apart from solid white lines, there are many other road markings that vehicles are not allowed to cross, and if caught, drivers will also face fines and penalty points. Examples include solid white lines separating lanes in the same direction and solid yellow lines (single or double) prohibiting vehicles from crossing in either direction. Precautions for driving on the road: 1. Meaning of white lines: Most road traffic markings are white. White dashed lines separate lanes traveling in the same direction and allow lane changes by crossing the lines, while solid white lines prohibit crossing and often appear as extensions of dashed lines before intersections. When traffic lights change at intersections, vehicles can pass through quickly. Combined with directional signs at intersections, solid white lines separate straight-moving vehicles from those turning left or right to prevent straight-moving vehicles from affecting turning ones. 2. Common violations: Most violations captured by electronic surveillance for crossing or running over lines occur when vehicles cross or run over single solid lines at intersections. However, if a driver is forced to cross the line—for example, on the downhill slope under the Century Bridge, where one lane is blocked by an accident or official vehicles (such as bridge maintenance)—then crossing the line to change lanes is permissible.

How to reset the maintenance light of a 2017 Great Wall Haval H6?

Insert the key and keep the engine off, then press the reset button once. Below is a detailed introduction to the Haval H6: 1. Brand Positioning: The Haval H6 is primarily designed not for urban road conditions in big cities but for road conditions in third-tier cities and vast rural areas. It meets the needs of consumers who require roads that are not too rough, occasionally travel on rural paths, or go up and down mountain roads, once again aligning closely with user requirements. 2. Exterior Design: The Haval H6 features a spacious interior with ample legroom in the front seats, making it suitable for occasional cargo hauling. Its design is bold and caters to the preferences of Chinese consumers.

Why is the Car Suspension So Hard and Bumpy?

Generally, excessive stiffness in the suspension is due to the car being new, as the mechanical components have not yet fully broken in. It is normal for the owner to feel that the suspension is too hard, and it will improve after the break-in period. Additionally, tire pressure should be maintained within the normal range, as excessively high tire pressure can also affect driving stability. Symptoms of damaged shock absorbers: 1. Shock absorber oil leakage: A normal shock absorber has a dry and clean exterior surface. If oil is seeping out, it indicates that the hydraulic oil inside the shock absorber is escaping from the upper part of the piston rod, meaning the shock absorber is essentially failing. 2. Clunking noise from the wheels: When the car passes over bumpy roads or speed bumps, a clunking noise from a particular wheel indicates poor or failed damping performance of the shock absorber on that wheel. 3. Increased body roll: When cornering, a noticeable increase in body roll, or even skidding in severe cases, is mainly due to insufficient damping force from the shock absorber, which fails to effectively suppress the compression of the springs.
