What are the requirements for fire extinguishers during annual vehicle inspections?

There are specific requirements for in-vehicle fire extinguishers during annual vehicle inspections, as follows: Within the validity period: Used fire extinguishers must be sent to maintenance units with fire extinguisher repair licenses for inspection, refilling of extinguishing agents, and propellant gases. Regardless of whether they have been used, fire extinguishers must undergo maintenance when they exceed the manufacturer's validity period. Passing hydrostatic pressure tests: In-vehicle fire extinguishers must undergo hydrostatic pressure tests every two years and can only continue to be stored in the vehicle after passing the tests. No deformation in the cylinder: The exterior of the in-vehicle fire extinguisher must be inspected to ensure there is no rust or deformation. Additionally, the nozzle should be checked for deformation, cracks, or damage. In-vehicle fire extinguishers are specifically designed for car fires and come in two main types: non-pressurized suspension-type ultra-fine dry powder automatic fire extinguishing devices for vehicles and pressurized suspension-type ultra-fine dry powder automatic fire extinguishing devices for compact cars. During annual vehicle inspections, a fire extinguisher must be placed inside the vehicle; otherwise, the inspection cannot be passed.

What do P, R, N, D, S, M mean in automatic transmission cars?

P, R, N, D, S, M in automatic transmission cars refer to the corresponding gear positions, where P stands for Parking, R for Reverse, N for Neutral, D for Drive, S for Sport, and M for Manual mode. The detailed explanations are as follows: D - Drive: The most commonly used gear. Gear shifting can be controlled by the accelerator pedal. P - Parking: After the car stops, engaging P gear prevents the vehicle from moving. Unlike N gear, P gear interrupts power output. N - Neutral: Temporarily stops the vehicle's movement when parked, but power is not interrupted. For example, when waiting at a traffic light, the handbrake should be applied simultaneously. This gear is prohibited when going downhill. R - Reverse: This gear can only be engaged when the vehicle is stationary. For models with a lock button, the button must be pressed to switch. S - Sport: The difference between D gear and S gear is only that the computer switches to a different shifting program. Therefore, S gear can be switched at any time without causing damage to the transmission. It is suitable for overtaking and climbing hills, but not recommended for other scenarios due to higher fuel consumption. M - Manual mode: This gear is unique to cars with a manual-automatic transmission, allowing drivers to enjoy the fun of manual shifting.

Which car models have a dashboard displaying 300?

There are many cars with a 300 mph speedometer. Basically, any performance car or sports car will have a speedometer that goes up to at least 300 mph. This doesn't even include some supercars like Pagani, Bugatti, and Koenigsegg, whose speedometers typically display up to 400 mph or more. Performance cars include the Mercedes-AMG series, BMW M series, Audi RS series, Volkswagen R series, and more. Additional Information: 1. Some high-end models also feature a 300 mph speedometer, such as the Audi A4L, A6L, A7, and A8L. However, due to electronic speed limiters, it's difficult to actually reach 300 mph. The Audi A6, A7, and A8 also have a 300 mph speedometer. The base A6 1.8T model, with a 190-horsepower L4 engine, has a top speed of 235 mph—far below the 300 mph displayed. In terms of power, it uses a 2.0T engine with a maximum output of 190 horsepower and a peak torque of 320 Nm, paired with a 7-speed AT transmission. There's also a 3.0T V6 engine and a hybrid version available, with the latter delivering up to 340 horsepower and a maximum torque of 500 Nm, offering explosive performance. 2. The new CT6 has a speedometer that displays either 300 mph or 280 mph, depending on the variant. The older models had a maximum torque of 400 Nm, but the torque plateau was in the less commonly used 3000-4300 rpm range. The newer models, while having a reduced maximum torque of 350 Nm, offer a much earlier torque plateau, delivering peak torque between 1500-4000 rpm—a more practical range for everyday driving.

Why is the car air conditioning cooling down very slowly?

Here are the reasons why the car air conditioning cools down very slowly: 1. Excessive refrigerant causing insufficient cooling. This usually occurs due to overcharging of refrigerant during maintenance, as there is a specific proportion requirement for refrigerant volume in the air conditioning system. 2. Insufficient refrigerant causing a lack of cooling. The main cause of insufficient refrigerant is usually leakage in the system. 3. Excessive impurities in the refrigerant and lubricating oil, causing minor blockages and insufficient cooling. If there are too many contaminants in the refrigerant and lubricating oil throughout the air conditioning system, the filter screen will inevitably become clogged, reducing the flow capacity of the refrigerant, increasing resistance, and decreasing the amount of refrigerant flowing to the expansion valve, leading to insufficient cooling. 4. Moisture infiltration in the air conditioning refrigeration system causing insufficient cooling. There is a component in the refrigeration system called the dryer (or receiver), whose main task is to absorb moisture from the refrigerant to prevent excessive moisture from reducing cooling capacity. 5. Air in the system is another cause of insufficient cooling. Once air enters the air conditioning system, it will increase the pressure in the refrigeration lines, and poor refrigerant circulation will also lead to insufficient cooling. 6. Reduced heat dissipation capacity of the condenser will also lead to decreased cooling performance of the air conditioning system. 7. Other reasons, such as low power supply voltage causing reduced electromagnetic clutch engagement or oil contamination between the clutch pressure plate and the pulley, can result in "slipping" phenomena similar to a loose drive belt.

What to Do If Your Driver's License Has Been Deducted More Than 12 Points?

If the points deducted reach 12, after the driver's license is confiscated, you must go to the relevant authority within 15 days to study road traffic safety laws, regulations, and related knowledge, usually for 7 days. After that, the vehicle management office will conduct a test within 20 days. If you fail, you must continue studying and taking the test. If you pass, the points will be cleared, and your driver's license will be returned. The handling method for deducting 12 points in one scoring cycle is as follows: 1. Within 15 days, go to the traffic management department of the public security authority to participate in a 7-day study of road traffic safety laws, regulations, and related knowledge (Subject One), then take the test. If you pass, the points will be cleared; 2. If a motor vehicle driver accumulates 12 points in one scoring cycle, the traffic management department of the public security authority shall confiscate their motor vehicle driver's license; 3. The motor vehicle driver shall, within 15 days, go to the traffic management department of the public security authority at the place where the driver's license was issued or where the violation occurred to participate in a 7-day study of road traffic safety laws, regulations, and related knowledge. After the motor vehicle driver completes the study, the vehicle management office shall conduct a test on road traffic safety laws, regulations, and related knowledge within 20 days; 4. If the test is passed, the points will be cleared, and the motor vehicle driver's license will be returned. If the test is failed, the driver must continue studying and taking the test. If the driver refuses to participate in the study or take the test, the traffic management department of the public security authority will announce the suspension of their motor vehicle driver's license.
