Is there a concept of wrong-way driving in non-motorized vehicle lanes?

There is indeed a concept of wrong-way driving in non-motorized vehicle lanes. Electric vehicles should proceed straight after ensuring safety when traveling in non-motorized vehicle lanes. Additional information is as follows: 1. When riding bicycles, electric bicycles, or tricycles across motor vehicle lanes on road sections, riders should dismount and push their vehicles. If there are pedestrian crossings or pedestrian crossing facilities, they should use them to cross. In the absence of pedestrian crossings, crossing facilities, or when it's inconvenient to use such facilities, they should cross only after ensuring safety. 2. Non-motorized vehicles that cannot travel in their designated lanes due to obstruction may temporarily use adjacent motor vehicle lanes in the affected sections, but must promptly return to the non-motorized vehicle lane after passing the obstructed area. Motor vehicles encountering such situations should slow down and yield.

Should the Damaged Underbody Guard Plate Be Replaced?

Car underbody guard plate damage requires replacement. The car underbody guard plate is the engine's protective plate, which effectively safeguards the vehicle's transmission and engine oil pan. Once damaged, it needs to be replaced. When replacing, you can consider installing an iron engine guard plate. Introduction to Various Types of Engine Guard Plates: Plastic and resin-made guard plates offer certain protective effects but are not durable, especially in harsh environments where they may quickly break. However, their advantage is obvious: they are lightweight and do not add much burden to the car. Iron guard plates have strong impact resistance and are quite durable, but they are heavy and can generate significant noise when driving on gravel roads. Aluminum alloy guard plates are currently more recognized; they are lightweight, offer good protection (though slightly inferior to iron ones), and produce no noise, but they are more expensive. Polymer alloy, an improved high-molecular polymer alloy material, has performance similar to metal in various aspects and can directly replace metal. Engine guard plates made of polymer alloy provide excellent protection but are not as durable as aluminum alloy materials, especially under large temperature variations, where cracks may appear.

How long does it take for the rearview mirror heating to take effect?

Rearview mirror heating takes effect in 10-15 minutes. Here is the relevant introduction about rearview mirrors: 1. Function: The rearview mirror is a tool that allows the driver to directly obtain external information about the rear, side, and lower parts of the car while sitting in the driver's seat. It is designed for the convenience of the driver's operation, preventing traffic safety accidents and ensuring personal safety. 2. Classification: Interior rearview mirror: The interior rearview mirror is designed to allow the driver to confirm the rear situation without significantly changing the forward line of sight while driving. Exterior rearview mirror: Passenger cars generally install exterior rearview mirrors on the doors. Under-mirror: It enables the driver to see areas outside the front and rear wheels under the car body through the mirror directly in front of the driver's seat.

Is Engine Repair Additive Useful?

Engine repair additive is useful. Additional information: 1. Main functions of the repair additive: The repair factors in the additive work on the worn parts of various metal components inside the engine and form a protective metal film on the surfaces. 2. This protective film not only prevents metal wear but also enhances cylinder pressure. The increased thickness of the protective film between metals reduces gaps, thereby improving sealing performance and alleviating engine oil burning issues. 3. Symptoms such as engine overheating, increased fuel and oil consumption, reduced power output, and difficulty in cold starts may occur. At the same time, due to deteriorating lubrication conditions, friction between engine components intensifies, wear accelerates, and clearances further increase, leading to abnormal fitting relationships, increased engine noise, worsened operational stability, and in severe cases, necessitating an engine overhaul.

What are the methods for charging a battery?

There are five methods for charging a battery: constant current charging, constant voltage charging, constant voltage charging with a fixed resistor, step constant current charging, and floating charging. Constant current charging method: During the charging process, the charging current remains unchanged, which is called the constant current charging method, abbreviated as CC charging or constant current charging. As the battery voltage gradually increases during charging, the charging current gradually decreases. To prevent the charging current from decreasing due to the rising battery voltage, the power supply voltage must be gradually increased to maintain a constant charging current. This requires a high level of automation in the charging equipment, and generally, simple charging devices cannot meet the requirements of constant current charging. Constant voltage charging method: During the charging process, the charging voltage remains unchanged, which is called the constant voltage charging method, abbreviated as CV charging or constant voltage charging. Since the power supply voltage remains constant from the beginning to the end of charging, the charging current is quite large at the start, significantly exceeding the normal charging current. However, as charging progresses, the battery voltage gradually rises, and the charging current gradually decreases. When the battery voltage equals the charging voltage, the charging current drops to a minimum or even zero. The advantage of the constant voltage charging method is that it can prevent excessive charging current in the later stages, which could cause active material shedding from the plates and energy loss. The required power supply voltage is approximately 2.4–2.8V per cell for acid batteries and 1.6–2.0V per cell for alkaline batteries. Constant voltage charging with a fixed resistor: This is a method used to compensate for the shortcomings of constant voltage charging. A resistor is connected in series between the power supply and the battery, allowing the initial charging current to be adjusted. However, the maximum charging current is sometimes limited, so as the battery voltage rises during charging, the current decreases almost linearly. Sometimes two resistor values are used, switching from a low to a high resistor at around 2.4V to reduce gas generation. Step constant current charging method: This method combines the characteristics of constant current and constant voltage charging. The battery is charged with a larger current in the early stages, then switched to a smaller current after a period, and finally to an even smaller current in the later stages. This method, which uses different currents in different stages for constant current charging, is called step constant current charging. Most step constant current charging processes can be divided into two or more stages. This method requires less charging time and achieves good results. Since a smaller current is used in the later stages, it reduces the washing effect of gas bubbles on the active material of the plates and minimizes material shedding. This method extends the battery's service life, saves energy, and ensures thorough charging, making it a commonly used charging method. Most batteries are charged at the first stage with a current rate of 10h, and at the second stage with a current rate of 20h. The duration of each stage varies depending on the specific requirements and standards of different batteries. Floating charging method: Intermittently used batteries or those only used during AC power outages are charged using the floating charging method. Most stationary batteries used in special applications are charged using this method. The key advantage of floating charging is that it reduces the battery's gas generation rate and prevents overcharging. At the same time, since the battery is connected in parallel with the DC power supply, it can instantly deliver a large current when high-power devices are in use, helping to stabilize the voltage of the power system and ensuring normal operation of electrical equipment. The disadvantage of floating charging is that some batteries may not be charged evenly or sufficiently, so periodic equalization charging is required. Functions of the battery: Provides a strong starting current to the starter when starting the engine; assists the generator in supplying power to electrical devices when the generator is overloaded; supplies power to electrical devices when the engine is idling. Battery maintenance: Start the car regularly to charge the battery; add distilled water or a special replenishing solution when the electrolyte is low; frequently check the small holes on the battery cover for ventilation during daily use; inspect the positive and negative terminals for signs of oxidation.
