What does the diamond-shaped dashed line on the road mean?

The diamond-shaped dashed line on the road is a longitudinal deceleration marking for vehicle lanes. Here are the specific details about the diamond-shaped dashed line on the road: 1. Location: Bridge approaches and turning sections. 2. Function: At the starting position of the longitudinal deceleration marking, a 30-meter transition section is set up. The diamond-shaped dashed line gradually widens from 10 cm to 30 cm. This is one of the new markings added in the latest national standard for road traffic markings (GB5768.2-2009). When vehicles pass through sections with longitudinal deceleration markings, drivers visually perceive the lane narrowing gradually, which heightens their attention and prompts them to actively reduce speed and proceed cautiously. This effectively prevents drivers from slamming on the brakes just before the stop line. Pedestrians on crosswalks can noticeably sense vehicles yielding, enhancing their sense of safety and reflecting a harmonious traffic environment between vehicles and pedestrians.

Is Car Brake Pad Rust a Serious Issue?

When rust appears on car brake pads, it should be addressed promptly. Here is more information: 1. Slight rust on brake pads. Most brake discs are made of cast iron. In humid or rainy weather, combined with prolonged exposure to wind and sun, if the vehicle is parked for an extended period, rust will naturally form on the surface. If the rust is minor and has not corroded the brake disc, simply lightly applying the brakes after starting the car can easily remove the rust through the friction between the brake pads and the disc. 2. Severe rust on brake pads. If the rust is severe, it is best to take the vehicle to a repair shop, remove the brake disc, and thoroughly sand off the rust with sandpaper. Check the brake pad surface for any abnormalities, reinstall properly, and conduct a road test. Drive at 70 km/h on a flat road and perform multiple braking tests to ensure no abnormalities. If vibrations persist, it indicates unevenness on the brake disc surface, requiring further polishing or replacement as necessary.

Deadline for China 5 Vehicle Registration?

After the implementation of the China 6 standard, the registration of China 5 vehicles was discontinued. The deadline for China 5 vehicle registration varies depending on the implementation of the China 6 standard in different regions. The following are the differences between China 5 and China 6 vehicles: 1. Different carbon monoxide emission requirements: China 5 vehicles have a carbon monoxide content of 1000mg per kilometer; China 6 vehicles have a carbon monoxide content of 500mg per kilometer. 2. Different letter representations: China 5 is represented by V; China 6 is represented by VI. 3. Different issuing departments: The China 5 standard was issued by the Ministry of Environmental Protection; the China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine. 4. Different control levels: The emission control level of the China 5 standard is equivalent to the fifth-stage emission standard currently implemented in Europe; the emission control level of the China 6 standard is a standard formulated to prevent and control environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled ignition engine vehicles and to protect human health.

How to Remove Car Emblems Without Leaving Marks?

About the introduction of removing car emblems without leaving marks as follows: 1. You can use hot water. Prepare a pot of hot water and slowly pour it over the emblem. The emblem is attached to the car body with industrial adhesive, and hot water will cause the industrial adhesive to lose its stickiness, thus the emblem will fall off. 2. You can use a hair dryer. Use the hot air from the hair dryer to blow on the emblem. After heating, the industrial adhesive will temporarily lose its stickiness, and the emblem can be easily removed. 3. Use essential balm. Essential balm has the effect of dissolving industrial adhesive. By slowly soaking and dissolving with essential balm, the emblem can be removed.

How to Test a Relay?

Testing a relay involves the following methods: 1. Measure the coil resistance: Use a multimeter set to the R×10Ω range to measure the resistance of the relay coil, which helps determine if the coil is open. The resistance of the relay coil is closely related to its operating voltage and current. The operating voltage and current can be calculated based on the coil resistance. 2. Measure the contact resistance: Use the resistance range of the multimeter to measure the resistance between the normally closed contact and the moving contact, which should be 0; the resistance between the normally open contact and the moving contact should be infinite. This helps distinguish between the normally closed and normally open contacts. 3. Measure the pull-in voltage and current: Use an adjustable regulated power supply and an ammeter. Apply a voltage to the relay and monitor the current in the power circuit with the ammeter. Gradually increase the power supply voltage until the relay pulls in, then record the pull-in voltage and current. For accuracy, repeat the test several times and calculate the average. Measure the release voltage and current: Connect the test as described above. After the relay pulls in, gradually decrease the power supply voltage until the relay releases, then record the voltage and current. Repeat the test several times to obtain the average release voltage and current. Generally, the release voltage is about 10-50% of the pull-in voltage. If the release voltage is too small (less than 1/10 of the pull-in voltage), the relay cannot function properly, which may threaten circuit stability and reliability.

How many kilometers can a car travel per hour?

A car's travel distance per hour depends on its actual speed. Generally, the average speed of a small car is 60KM/h. The driving conditions of cars with different displacements: 1. 1.6 displacement: The maximum speed of a 1.6 displacement car is 180KM/h, meaning it can travel up to 180 kilometers in an hour under optimal conditions. 2. 2.4 displacement: For a 2.4 displacement car, the maximum speed can reach 200KM/h, meaning it can travel up to 200 kilometers in an hour, also under unrestricted conditions.
