Reasons why car bumpers are made of plastic: Mainly to absorb and cushion external impacts, thereby protecting the vehicle body, pedestrians, and occupants. When a car collides at low speed, the plastic bumper's cushioning effect can protect the vehicle body to some extent. Additionally, due to the plastic bumper's crushable characteristics, it can also protect pedestrians in the event of a collision. A heavier vehicle would significantly increase fuel consumption and emissions, which is detrimental to the environment. With increasingly stringent regulations on vehicle emissions, reducing the vehicle's weight from the ground up is essential. This is a trend in automotive development, aimed at improving fuel economy and protecting the environment, hence the design of plastic bumpers. Besides lowering fuel consumption, plastic bumpers also enhance performance.

What to Do If It Rains During the Driving Test?

Solutions for taking the driving test in the rain: Maintain a positive mindset and relieve stress. After getting in the car, use a tissue to wipe the rearview mirrors and test the windshield wipers, adjusting the frequency based on the intensity of the rain. Tips for taking the driving test on a rainy day are as follows: 1. Do not close the car windows too tightly, as this can cause fogging inside the car, obstructing visibility and affecting judgment accuracy. 2. Control your speed when driving in the rain, going slightly slower than during regular training. 3. During the test, avoid sudden acceleration or hard braking. Rain makes the road slippery, visibility poor, and increases the risk of wheel skidding. 4. Turn on the windshield wipers promptly when it rains to maintain clear visibility.

Can 4-Square-Millimeter Copper Wire Be Used for Vehicle Jump-Starting?

4-square-millimeter copper wire can be used for vehicle jump-starting. Below is an introduction to the 4-square-millimeter copper wire: Application Scope of 4-Square-Millimeter Copper Wire: A 4-square-millimeter copper wire can serve as a jump-start cable. Its diameter is approximately 1.27 millimeters. By twisting two strands of 4-square-millimeter copper wire together, the current capacity can be increased. As long as the current is increased and the voltage remains stable, the power output will also increase, meeting the load requirements and ensuring normal operation. Specific Measures for 4-Square-Millimeter Copper Wire: During the actual operation, the protective cover of the battery must be opened to locate the positive terminal. The red end of the wire should be securely connected to the positive terminal of the battery, ensuring a tight clamp. Then, connect the positive terminal to another positive terminal to measure a voltage of 12 volts.

What are the reasons for the sudden failure of the Citroen C-Quatre's air conditioning to cool?

The reasons for the Citroen C-Quatre's air conditioning not cooling are: 1. Damage to the piston inside the air conditioning system. 2. Damage to the clutch plate. 3. The engine ECU does not instruct the air conditioning to work. 4. The condenser fins in the air conditioning system are too dirty, causing the pressure and temperature in the system to rise too high. To protect the system, the air conditioning pump stops working, resulting in no cooling. Additional information: The cooling principle of car air conditioning is the same as that of household air conditioning. Both use the principle that R12 or R134a expands rapidly when compressed and released, absorbing a large amount of heat. In the cooling system, the low-pressure vapor of the refrigerant is sucked in by the compressor, compressed into high-pressure vapor, and then discharged to the condenser. The indoor air continuously circulates to achieve the purpose of lowering the temperature.

What to Do When the Key is Locked Inside a Wuling Sunshine?

If the key is locked inside a Wuling Sunshine, you can try the following methods to resolve the issue: 1.
