What is a Linear Guidance Sign?

Linear guidance signs are traffic signs used to guide or warn drivers of changes in the horizontal alignment of the road ahead, prompting them to adjust their driving direction appropriately according to the alignment to ensure safe operation. Here are the specific details: 1. Location: Linear guidance signs should be installed on road sections where the driving direction changes, such as small-radius curve sections, ramps, sharp bend sections, etc. 2. Direction: The placement of linear guidance signs should align with the road alignment and be perpendicular to the direction of vehicle travel. Here are some additional details: 1. Spacing: The spacing of linear guidance signs should ensure that at least two signs are always within the driver's field of vision. 2. Angle: For curve sections with a small deflection angle, one guidance sign can be placed at the midpoint of the curve; for curves with a large deflection angle or long curve sections, multiple guidance signs can be installed as needed. 3. Height: The minimum installation height of linear guidance signs should be 1.2 meters from the lower edge of the sign to the ground.

Is Purchase Tax Required for Second-hand Car Transfer?

No additional vehicle purchase tax is required for the transfer of a second-hand car. The main reason is that the vehicle purchase tax follows a one-time collection system, which should be completed when the original owner purchases the vehicle. Therefore, during the transfer of a second-hand car, the new owner only needs to request the tax payment certificate from the original owner. Here are some additional details: 1. The vehicle purchase tax is collected once: Once the vehicle purchase tax has been paid for a vehicle, it will not be levied again. 2. The vehicle purchase tax is collected by the State Taxation Administration: The tax must be paid in full at once. The taxpayer must present the tax payment certificate or tax exemption certificate issued by the competent tax authority to the vehicle management agency of the public security bureau for vehicle registration. Without the tax payment certificate or tax exemption certificate, the vehicle management agency will not process the vehicle registration. 3. When purchasing a second-hand car, the buyer should request the tax payment certificate from the original owner: The tax payment certificate consists of an original and a duplicate, issued per vehicle, with one certificate per vehicle. The original is kept by the owner, and the duplicate is used for vehicle registration.

What is the friction coefficient of automotive brake pads?

The friction coefficient of graphite material front brake pads for automobiles is 0.44 ±0.05, while that of graphite material rear brake pads is 0.37 ±0.05. For ceramic material front brake pads, the friction coefficient is 0.42 ±0.05, and for ceramic material rear brake pads, it's 0.37 ±0.05. These specifications are suitable for the Chinese market and belong to the FF grade. The friction coefficient of automotive brake pads refers to the parameter indicating the friction efficiency of the brake pads, serving as a crucial factor in evaluating their quality. A lower friction coefficient results in reduced friction force, making the vehicle more prone to slipping, whereas a higher friction coefficient increases friction force, enhancing slip resistance. Both excessively high and low friction coefficients can adversely affect braking performance. If the friction coefficient is too high, it may lead to wheel lock-up during braking, compromising comfort and heat resistance. Conversely, if the friction coefficient is too low, it can result in unresponsive braking. Both scenarios pose serious threats to driving safety, necessitating flexible adjustments based on actual conditions.

How often should water be added to a car's radiator?

Normally, the coolant level in the radiator should be between the MIN and MAX marks. When the coolant level in the reservoir drops below the minimum mark, it's time to add water promptly. Here are the details: 1. Replacement cycle: The coolant in the radiator should generally be replaced every two years or every 30,000-40,000 kilometers driven. Vehicles with high usage frequency should consider replacing it earlier. 2. Precautions: Only add coolant, never use tap water. Tap water tends to boil easily and contains many impurities that can lead to rust and scale formation. Here are some additional details: 1. Choose coolant based on the vehicle's origin: Domestic and imported vehicle coolants should not be mixed. Therefore, when purchasing, select the appropriate coolant based on your vehicle's origin. The rust inhibitors, defoamers, and dyes in imported vehicle coolants have different chemical compositions from those in domestic coolants. Mixing them can cause chemical reactions, leading to scaling, corrosion, and other adverse effects. 2. Try to choose all-season coolant. Most coolants available today are all-season, which eliminates the hassle of changing coolant in winter.

Which is More Durable: CVT or AT Transmission?

AT transmissions are generally more durable than CVT transmissions. Here are the details: 1. AT Transmission: This refers to automatic transmission. The advantage of this transmission is its relatively stable technology, while the main drawbacks are higher costs and greater development difficulty. However, as the most mature automatic transmission technology, AT transmissions still have broad development prospects in the future. 2. CVT Transmission: This stands for continuously variable transmission. Its biggest advantage is superior smoothness, with almost no noticeable jerking. The main disadvantages are limited torque capacity and inconvenient maintenance. 3. Comparison: Overall, AT transmissions offer stronger reliability and can handle high-displacement and high-torque engines, but they fall short in terms of smoothness and fuel economy. Additionally, they require frequent system upgrades, resulting in higher maintenance costs. In contrast, CVT transmissions are more economical and excel in shift smoothness - CVT is second to none in this aspect. However, this type of transmission is mostly used in small-displacement vehicles and isn't as widely adopted as AT transmissions.
