What is the maximum speed limit on highways?

Highways have a maximum speed limit of 120km/h. Highways should clearly indicate the speed limits for each lane, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour. On highways, the maximum speed for small passenger vehicles should not exceed 120 kilometers per hour, while other motor vehicles should not exceed 100 kilometers per hour. Relevant regulations: For roads with 2 lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; for roads with 3 or more lanes in the same direction, the minimum speed for the leftmost lane is 110 kilometers per hour, and the minimum speed for the middle lane is 90 kilometers per hour. If the speed indicated by road speed limit signs is inconsistent with the above lane speed regulations, drivers should follow the speed indicated by the road speed limit signs. If the speed indicated by road speed limit signs is inconsistent with the above lane speed regulations, drivers should follow the speed indicated by the road speed limit signs.

How does a car charge its battery?

The principle of a car charging its battery is as follows: 1. Float charging: After the battery is charged, due to impurities in the electrolyte and plates, partial discharge occurs on the plates. Therefore, to keep the battery in a fully charged standby state, the battery is connected in parallel with a 12V charger to the DC bus. The 12V charger not only handles the regular DC load but also provides an appropriate charging current to the battery. This method is called float charging. 2. Equalization charging: Equalization charging is a method to balance the characteristics of the battery. During the use of the battery, due to individual differences and temperature variations, the terminal voltage of the battery may become unbalanced. To prevent this imbalance from worsening, the charging voltage of the battery pack is increased to perform an activation charge on the battery.

What does push-auto mean?

The push-auto on a vehicle refers to the one-button start intelligent system. Modern vehicles are typically equipped with a one-button start function, which is used to start or stop the engine. The one-button start intelligent system differs from traditional mechanical key ignition methods and conventional starting procedures. Simply press the one-button start button to start or stop the engine, eliminating the hassle of losing or searching for keys. The correct method to start a car with one-button start is as follows: After the driver sits in the driver's seat, there is no need to press the brake pedal. Simply press the start button once, at which point the ACC light will turn on. Press it once more, and the vehicle will perform a self-check. Press the brake pedal, then press the start button again to ignite and start the engine. Release the foot brake. You can choose to warm up the car in place, with the duration depending on the environment. Press the foot brake again, shift to D gear, and release the handbrake (for electronic handbrakes, simply press the button briefly). Slowly release the foot brake, start moving, and smoothly press the accelerator pedal according to road conditions to drive safely.

How to resolve the OBD light on the car display screen?

You can use a diagnostic tool to read the fault code and clear it accordingly. Here is some information about OBD: 1. The full English name of OBD is On-Board Diagnostics, which translates to the onboard automatic diagnostic system in Chinese. 2. The primary purpose of the automatic diagnostic system is to monitor the engine's operating condition and check whether the vehicle's exhaust emissions exceed the standard. Once the vehicle's exhaust emissions exceed the standard, the OBD warning light will immediately illuminate. When the OBD light on the vehicle turns on, it indicates an issue with the vehicle's emissions, requiring immediate inspection.

Which Engine Oil is Suitable for Turbocharged Engines

Turbocharged engines should use fully synthetic engine oil. Here is some information about engine oil: 1. There are three types of engine oil used in vehicles: mineral oil, semi-synthetic oil, and fully synthetic oil. The service intervals and performance of these three types of oil vary. 2. The service interval for mineral oil is 5,000 kilometers, for semi-synthetic oil it is 6,500 kilometers, and for fully synthetic oil it is 10,000 kilometers. 3. Currently, the most popular vehicles in the market are those equipped with turbocharged engines, as the biggest advantage of turbocharged engines is that they can enhance the power and torque of the engine without increasing its displacement.

Can a tire with a nail puncture but no air leakage still be used?

Tire with a nail puncture but no air leakage can be used depending on the situation. Here is the relevant introduction about tire air leakage: Correct approach when a tire is punctured by a nail: When a tire is punctured by a nail, first determine whether there is air leakage and how severe it is. After locating the puncture site, apply some soapy water with foam around the area, then observe if there is air leakage or bubble formation, and how severe the phenomenon is. If there is no air leakage, you can temporarily rest assured and drive a short distance. However, you should not ignore it just because there is no air leakage; drive at a low speed to the nearest repair shop. Precautions for tire use: When the surface of the car tire wears to the position of the triangle symbol, it should be replaced in time to prevent safety hazards. After replacing or repairing the tire, perform a four-wheel alignment and dynamic balance in time to prevent abnormal shaking when the car is driving at high speed. Avoid driving at high speed over potholes to prevent tire blowouts.
