National III emission standard vehicles may only be allowed to operate for 2 more years. There is no precise timeline as regulations vary by region. Introduction to National III standard: The National III standard represents China's third-stage vehicle emission requirements, equivalent to the Euro III emission standards in terms of tailpipe pollutant levels. The key difference is that new vehicles must be equipped with an OBD (On-Board Diagnostics) system. This system features increased monitoring points and enhanced detection capabilities, with oxygen sensors installed at both the inlet and outlet of the three-way catalytic converter. Through real-time emission monitoring, compliance is strictly controlled, ensuring better enforcement of Euro III emission standards. Latest policy on National III vehicle retirement: Under current domestic policies, there is no mandatory retirement timeline for private passenger vehicles, only a recommended retirement guideline after reaching 600,000 kilometers. For light trucks and batch vehicles, the mandatory retirement period is 10 years, extendable up to 5 additional years. National III heavy trucks have a maximum mandatory retirement period of 15 years. Even if there are plans to phase out National III vehicles, this would likely occur after the full implementation of National VI standards, which isn't expected until 2023. Therefore, there remains ample time before National III vehicles face retirement deadlines.

Should Turbocharged Cars Install Underbody Protection Plates?

Whether a turbocharged car should install an underbody protection plate depends on the driver's habits and road conditions. For instance, frequent driving on low-lying or gravel roads necessitates the installation of a protection plate. Otherwise, prolonged exposure can lead to the accumulation of mud in the chassis and engine compartment, affecting vehicle performance. Below is an introduction to engine protection plates: 1. Definition of Protection Plates: A protection plate is a safeguarding device for the engine, essentially adding a protective layer to the car's underbody. 2. Function of Protection Plates: The engine underbody protection plate effectively prevents scrapes, keeps road mud and dust from entering the engine compartment, and indirectly extends the engine's lifespan.

Which Interior Colors Make a Car Look Premium?

Choosing the interior color of a car is similar to decorating a house—only with well-selected and coordinated colors can it exude a sense of style, while also reflecting the owner's personality. Here are some additional details: 1. Black: Black is a very common color and the choice of most car owners, as it is known for being stain-resistant and versatile. Some car models utilize black exceptionally well, showcasing different aesthetics through varying materials and designs, such as creating a sleek all-black "Black Knight" style. However, if the design lacks creativity, an all-black interior can appear monotonous, so it's best not to go completely black. Since black is highly versatile, pairing it with other colors—such as red or beige—often works well without looking odd. 2. Common Colors: Most car manufacturers now offer a wide range of interior color options, including popular choices like black, white, brown, red, and beige.

Where is the steering wheel zero position?

Steering wheel zero position is at the very top of the steering wheel. Precautions for holding the steering wheel: 1. Avoid single-handed operation: While driving, except when necessary for operation, do not operate with one hand for a long time, nor place your hand on the gearshift or window frame for extended periods. When driving on bumpy roads, hold the steering wheel firmly with both hands to prevent loss of control and potential accidents. 2. Avoid excessive force: Do not turn the steering wheel too forcefully or make sudden movements. Avoid turning the steering wheel when the vehicle is stationary. 3. Regular checks: While driving, turn the steering wheel left and right to check if it moves smoothly, if there is any lack of return force, and whether the vehicle drifts when the steering wheel is released.

What is the difference between ENV6 brake fluid and DOT4?

The difference between ENV6 brake fluid and DOT4 lies in the boiling point of the brake fluid. Since the brake system operates at high temperatures—braking inherently relies on friction to stop the vehicle, and friction generates heat—DOT4 brake fluid has a higher boiling point than DOT3. 1. Performance comparison: Therefore, DOT4 performs better than DOT3, particularly in high-temperature conditions. The equilibrium reflux boiling point of DOT4 is 230°C, while that of DOT3 is 205°C. Vehicles using DOT4 brake fluid can brake more frequently. 2. Specifications: According to GB12981-2003 "Motor Vehicle Brake Fluid," brake fluids are classified into HZY3, HZY4, and HZY5, corresponding to DOT3, DOT4, and DOT5 internationally. DOT4 outperforms DOT3, especially in high-temperature performance.

Is it necessary to repaint minor scratches?

It is not necessary to repaint minor scratches on a car if they are superficial and do not expose the metal body. Here is some relevant information: 1. Large-area repainting: Repainting large areas can affect the vehicle's resale value. For example, under the same condition, a car that has been repainted will be cheaper than one with minor scratches that have not been repainted. 2. Faster aging: Repainted surfaces age faster than the original factory paint because the repair paint is not as high-quality as the original. Even if color differences are not noticeable at first, they may appear over time, and in severe cases, the paint may even peel off. If the scratch is deep enough to expose the metal, it should be addressed promptly. Otherwise, even a small break in the paint can cause the steel plate to start rusting, and by then, repainting may not effectively prevent rust.
