At what position should the pressure gauge needle of a fire extinguisher indicate normal pressure?

The pressure gauge needle of a fire extinguisher indicates normal pressure when it is in the green zone. The normal pressure value for a fire extinguisher is approximately between 1.2 to 1.5 MPa. If the pressure gauge needle is in the red zone, it means the pressure inside the cylinder is insufficient, indicating that the fire extinguisher cannot be used normally. If the needle is in the yellow zone, it indicates overpressure, which means the pressure is too high and can be dangerous. Fire is a chemical combustion reaction, typically caused by the reaction between oxygen in the air and certain fuels such as wood or gasoline. Of course, wood and gasoline do not spontaneously combust simply by coming into contact with oxygen; combustion only occurs when the fuel is heated to its ignition temperature. A fire extinguisher, also known as a fire cylinder, is a portable firefighting tool. It contains chemicals designed to extinguish fires. The fire extinguisher is a sturdy metal cylinder filled with water or fire-extinguishing materials. When the lever at the top of the cylinder is pressed, the high pressure generated forces the extinguishing agent inside the cylinder to be expelled, similar to how a spray can releases its contents. The function of a fire extinguisher is to displace air, depriving the fire of oxygen and causing it to extinguish. Because carbon dioxide is a gas and leaves no residue, it is particularly useful for electrical fires to avoid damaging equipment.

How is the speed divided on expressway lanes?

Speed division method for expressway lanes: For roads with two lanes in the same direction, the minimum speed on the left lane should not be less than 100 km/h; for roads with three lanes in the same direction, the minimum speed on the far-left lane should not be less than 110 km/h, and the minimum speed on the middle lane is 90 km/h. When driving normally on the expressway, the minimum speed should not be less than 60 km/h, the maximum speed for small passenger cars should not exceed 120 km/h, other motor vehicles should not exceed 100 km/h, and motorcycles should not exceed 50 km/h. At the same time, pay attention to traffic signs and do not exceed the speed indicated by the signs. In case of snow, rain, fog, wet or icy road surfaces, or poor visibility, promptly reduce the speed to a safe level and maintain a necessary safe distance. Avoid driving recklessly at high speeds, frequently overtaking, or speeding to prevent accidents.

What is the new policy for license plate transfer in 2020?

Both the 2020 regulations and previous rules do not allow the transfer of license plates. Currently, when a vehicle is transferred, the license plate cannot be transferred with the vehicle, nor can the license plate be transferred separately. The original license plate can only be transferred to the owner's new vehicle information and cannot be transferred to another person. However, there is one special case: spouses can transfer their license plates to each other with a marriage certificate, allowing the other party to obtain the license plate without going through the lottery or bidding process. New policies for license plate retention: 1. If a vehicle has been used for at least one year, the original license plate can be retained for up to 2 years; 2. The original license plate can be retained when the vehicle is transferred, deregistered, or relocated; 3. Both used and new vehicles are eligible for license plate retention applications.

Is it better to turn on ECON or not?

It is better to turn on ECON. When the driver activates the ECON switch, the vehicle enters a low-carbon and eco-friendly driving mode, automatically prioritizing fuel consumption control. The system proactively prevents excessive acceleration and deep throttle presses that lead to high energy consumption, achieving intelligent fuel savings. The ECU, engine, and transmission intelligently execute the driver's intentions in the mode of minimum fuel consumption, achieving better fuel economy through quick gear shifts and smooth acceleration. The air conditioning operates in an energy-saving state by reducing the fan's operating voltage and intelligently adjusting the cooling conditions to lessen the engine's load. Additionally, the speedometer displays real-time instantaneous fuel consumption through green, red, and blue indicator lights on both sides. When the driver presses the accelerator pedal deeply, the ECON system effectively controls the intake valve opening to ensure smooth engine operation while conserving energy.

Is Engine Cleaning Necessary?

Engine cleaning is necessary. A comprehensive cleaning of the engine compartment allows for a better understanding of the car's engine bay, especially after cleaning the engine surface, wiring surfaces, and plastic/rubber components, which helps the engine dissipate heat more efficiently and protects the wiring in the engine compartment. Benefits of cleaning the engine compartment: 1. Improved driving mood: A clean engine compartment looks tidy and can provide the driver with a more pleasant driving experience. 2. Prevents component damage: The engine compartment is not completely sealed, and dust and air can enter during operation. Over time, dust hardens into a crust on parts, wires, and oil lines, along with other impurities, which can reduce the lifespan of other components in the engine compartment and increase maintenance costs for the owner. 3. Detects fluid leaks: Cleaning the engine compartment allows for timely inspection of potential issues. If there are oil or fluid leaks, they can be detected early through cleaning, which is crucial for maintaining the vehicle's proper operation. Any detected leaks should be addressed promptly to prevent corrosion of wires and pipelines.

What is the symbol for fog lights?

The symbol for fog lights consists of three light rays covered by a wavy line. The front fog light is indicated by a green symbol with the three lines on the left side, while the rear fog light is represented by a red symbol with the three lines on the right side. Fog lights are used in special weather conditions with poor visibility. The light from fog lights has strong penetrating power, allowing other drivers to see your vehicle in low-visibility weather and helping to avoid collisions. Fog lights do not serve as illumination; if the headlights malfunction, fog lights cannot be used as a substitute for headlight illumination. Fog lights are only equipped on some high-end models, and some vehicles may only have front fog lights without rear fog lights. Some entry-level versions of certain models do not come with fog lights at all. If fog lights are essential for you, you can opt for higher-trim models when purchasing a car. Nowadays, many vehicles also come with daytime running lights, which are used during daytime driving. Daytime running lights can enhance safety during daytime driving. Car lights are relatively prone to malfunctions, and in some models, fog lights may be poorly designed, making them susceptible to water ingress and failure during operation, requiring timely repairs.
