Section speed measurement involves setting up two adjacent monitoring points on the same road section. Below is relevant information about section speed measurement: Section Speed Measurement: Section speed measurement involves setting up two adjacent monitoring points on the same road section. The average speed of a vehicle on that section is calculated based on the time it takes for the vehicle to pass between the two monitoring points. The speed is then compared to the speed limit for that section to determine if the vehicle has violated the speed limit. At the same time, the information of traffic-violating vehicles is displayed in real-time on LED screens to notify and warn more vehicles. Advantages of Section Speed Measurement: With traditional single-point speed measurement devices, drivers who are familiar with the location of the speed measurement point can avoid penalties by braking to reduce their speed, which can easily lead to rear-end collisions. In contrast, section speed measurement calculates the average speed to detect speeding, eliminating the possibility of drivers trying to cheat the system, making it more scientific and fair.

What is the fuel tank capacity of Honda CR-V in liters?

Honda CR-V has a fuel tank capacity of 53 liters, which is the officially announced data. Owners who have purchased a Honda CR-V can also check this information on the vehicle's configuration sheet. The recommended fuel grade for Honda CR-V is 92 octane, with a fuel consumption of 4.9 to 7.3L per 100 kilometers. A full tank of fuel can cover a distance of 699 to 1040 kilometers. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank. The fuel level is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is reserved to allow the fuel inside the tank to expand when the temperature rises without overflowing. If the fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

How to Identify China IV and China V Standards?

Methods to identify China IV and China V standards: Check the vehicle's environmental protection label; For new vehicles, refer to the factory certificate; Visit the vehicle management office for official inquiry; Or log in to the Motor Vehicle Environmental Protection Website and query by entering the vehicle's VIN number and the last 6 digits of the engine number. Below are relevant details: 1. Emission Regulations: There are three major global automotive emission standards: US, European, and Japanese. Although China's auto market has developed rapidly, its emission regulations started relatively late. Since 2000, China has implemented its first-phase emission standards based on European norms, followed by China II, III, IV, and now China V. 2. Differences between China IV and V: Compared to China IV, the China V standard reduces nitrogen oxide (NOx) emissions by 25% for light vehicles and 43% for heavy vehicles. The key difference is stricter NOx limits for heavy vehicles under China V. Additionally, standards for NOx + hydrocarbons (HCNOx), particulate matter (PM) concentration were raised. China V also introduced new metrics: particulate number (PN) and non-methane hydrocarbons (NMHC). China V standards are comparable to Europe's current Euro 5 emission control levels.

How to Solve the Hard Brake Issue in 2013 Peugeot 408?

Here are the solutions for the hard brake issue in the 2013 Peugeot 408: 1. Restart the engine: Try pressing the brake pedal firmly to restart the engine. Once the engine is running, the brake booster pump will resume operation, and the brake pedal will return to normal. Below is extended information on the causes of hard brakes: 1. Vacuum brake pump failure: The vacuum brake pump has two chambers: one connected to the intake manifold and the other to the external atmosphere. When the engine is running, the intake manifold draws in air at a high velocity, creating negative pressure (negative pressure chamber). The other chamber (positive pressure chamber) is connected to the atmosphere. During braking, the pressure difference between the two chambers generates assistance, applying pressure to the brake fluid to create friction between the brake pads and discs, thereby producing braking force. If this system fails, braking becomes difficult. 2. Brake booster pump issue: The brake booster pump only generates vacuum when the engine is running. When the engine is off, it relies on residual vacuum for assistance. Restarting the engine will restore normal function, indicating this is not a malfunction.

What Causes the BMW Fuel Gauge Needle to Stop Moving?

The reasons for the fuel gauge needle not moving are: issues with the fuel float or problems with the fuel gauge wiring. Below are the relevant details: 1. For older vehicles, it is likely that the fuel float is malfunctioning: (1) The fuel float is commonly referred to as the fuel level sensor. You can check if the fuel level sensor plug on the fuel tank is loose and observe whether there is any obstruction during the sliding process of the fuel level sensor. (2) If the fuel gauge needle reaches the top, it indicates that the fuel float is faulty. (3) If the needle does not move immediately after refueling, it may be because the fuel float is buoyed up by the fuel's buoyancy to the top of the tank. As the vehicle consumes fuel during driving, the fuel float will descend, and the fuel gauge needle will then move with the sensor. 2. Check if there is an issue with the fuel gauge wiring on the car's dashboard: The dashboard should be removed, and a multimeter and a pin should be used to accurately inspect the corresponding fuel gauge wiring on the dashboard. The car's fuel level gauge displays the amount of gasoline in the vehicle. It is particularly important to note that when the fuel gauge needle falls below the red line and the warning light comes on, although the car can still travel 30-40 kilometers, it is not recommended to wait until the fuel level warning appears before refueling.

Why Can't the OBD Be Connected During Vehicle Inspection?

At the vehicle management office, if the OBD cannot read data during inspection, it might be due to instrument malfunction, incomplete data, or compatibility issues with the vehicle. OBD inspection is a newly added item in recent years, primarily checking if the vehicle meets standards, including exhaust emissions. Here are the relevant details: 1. Reasons for OBD reading failure: The OBD reads information such as the vehicle's engine, emission after-treatment devices, and related fault codes. Since OBD inspection is a new addition, data reading failures are common. 2. Solutions: If the issue is due to instrument malfunction or the OBD diagnostic tool not supporting the communication protocol used by the vehicle's ECU system, try replacing the instrument for inspection. If the vehicle management office's system data is incomplete, you may need to wait for a data upgrade before reattempting the inspection. 3. OBD inspection results: The OBD inspection results directly affect whether the vehicle can be registered and pass the annual inspection. If the OBD data is abnormal, the vehicle will fail the annual inspection. Driving a vehicle without passing the annual inspection violates the "Road Traffic Safety Law," and traffic police can impose a 200-yuan fine and deduct 3 points from the driver's license, along with possible vehicle impoundment. If a vehicle fails to undergo annual inspection for three consecutive years, it will be forcibly scrapped.

What to Do If Your Vehicle Fails the Annual Exhaust Emission Test?

Solutions for failing the annual vehicle exhaust emission test include: 1. Cleaning the three-way catalytic converter; 2. Cleaning the front oxygen sensor; 3. Using higher-quality gasoline; 4. Checking the engine's working condition; 5. Accelerating and driving several kilometers on the highway. Reasons for failing the annual exhaust emission test are: 1. Poor fuel quality; 2.
