The Difference Between Independent Suspension and Non-independent Suspension

How is a 5-seater car penalized for carrying 6 people including children?

4-seater or 5-seater cars carrying 6 people exceed the approved passenger capacity by 20%. According to the "Scoring Standards for Road Traffic Safety Law Violations", driving passenger vehicles (excluding public buses) or school buses that exceed the approved passenger capacity by less than 20%, or driving other passenger vehicles that exceed the approved passenger capacity by more than 20%, will result in a penalty of 6 demerit points imposed by the traffic management department of the public security authority. Below is relevant information about overloading: 1. Hazards: Research has found that when a vehicle's axle load exceeds the standard load by one time, driving on the highway once is equivalent to a standard vehicle driving on asphalt pavement 256 times or on cement concrete pavement 65,536 times. Moreover, the larger the approved load capacity of the vehicle, the more severe the damage to the road caused by overloading. The maximum single rear axle load monitored in China reached 24 tons. Such a vehicle driving on a cement highway once is equivalent to a standard vehicle driving 1.21 million times. 2. Negative impacts: Overloading has caused significant harm to the healthy development of the transportation market. Overloading leads to market chaos, completely disrupting the basic price formation system of the transportation market. Under normal circumstances, transportation pricing is based on the cubic volume and weight of the goods. Overloaded vehicles severely pollute the atmospheric environment. To obtain greater traction, overloaded vehicles often drive at low gears with high throttle, causing incomplete combustion of engine fuel, resulting in excessive exhaust emissions, excessive noise, and severe pollution of the atmospheric environment.

Do Dash Cams Have Sound?

Dash cams generally have sound. Dash Cams: Dash cams are typically external cameras whose main function is to record the driving conditions outside the vehicle. However, they can also record sounds inside the car but cannot capture images of the interior. Wiring for Dash Cams: Most dash cams have two wiring methods: connecting to the cigarette lighter or connecting to the fuse box. The advantage of connecting to the cigarette lighter is that the wiring is simple, but it may affect aesthetics and occupies a cigarette lighter port. Normally, the cigarette lighter is connected to the ACC (Accessory) power, which only provides electricity when the car is powered on. Therefore, dash cams connected to the cigarette lighter cannot achieve 24-hour parking monitoring. Connecting to the fuse box allows direct connection to the car battery, enabling 24-hour parking monitoring. However, the drawback of connecting to the fuse box is that it is more complicated and usually requires professional installation. On the plus side, there are no exposed wires, making it look more aesthetically pleasing.

Which Cars Have Strong Climbing Power and Are Fuel-Efficient?

Recommended vehicles with strong climbing power and fuel efficiency include the Changan CS55PLUS, Geely Haoyue, and Haval H6. Below are some methods to save fuel: 1. Control RPM: While driving, the optimal engine RPM for most fuel-injected cars is around 2200–2500. Regardless of the gear, maintain the engine RPM within this range. Too low RPM will make the car sluggish, waste fuel without moving, and damage the engine; too high RPM increases unnecessary fuel consumption and also harms the engine. 2. Maintain Speed: The most fuel-efficient driving condition is steady, straight-line driving. The most fuel-efficient speed for small-displacement cars is 60–80 km/h, while for mid-displacement cars, it is 80–100 km/h. Driving at the economic speed ensures the best fuel efficiency.

Is 360-Degree Panoramic View Camera Practical?

360-degree panoramic view camera is not practical. Although the panoramic view technology is useful and has a strong sense of technology, its cost-performance ratio is not high. In fact, radar can completely replace the camera, but radar gives people a sense of insecurity, and drivers who are used to the camera may still feel worried. The following is an introduction to the 360-degree panoramic view camera: Installation method of 360-degree panoramic view camera: First, drill a hole in the car, remove the entire door panel, install the front camera on a suitable grille or emblem at the front of the car, mount the side cameras at the bottom of the left and right rearview mirrors, and then connect the wiring. Although the 360-degree panoramic view camera can be installed, the installation process is quite complicated, and the cost is not low. Impact of installing 360-degree panoramic view camera on the car: The installation process is generally invasive, requiring the removal of original car parts to some extent and connection to the original car wiring. If the wiring harness is poorly installed, minor issues like leakage may occur, while severe cases may lead to safety hazards such as fire.

How long should the engine be turned off in traffic jams

Whether to turn off the engine in traffic jams generally depends on the duration. It's recommended to turn off the engine if the wait exceeds five minutes. Reasons for turning off the engine during prolonged traffic jams: Turning off the engine can save fuel. During traffic jams, drivers often feel impatient. Once the traffic eases, some may accelerate abruptly. It's advised not to rush when starting, as aggressive acceleration not only harms the vehicle but also wastes fuel. Ensure smooth movement when starting and maintain a safe distance from the vehicle ahead during traffic jams. Reasons for keeping the engine running during short traffic jams: For brief stops of one or two minutes, it's unnecessary to turn off the engine. Since the vehicle may need to move at any moment, restarting after turning off the engine is equivalent to adding startup steps, which can easily lead to waiting and honking from vehicles behind, reducing road efficiency. For short-term traffic jams, manual transmission vehicles should shift to neutral and engage the handbrake, while automatic transmission cars should shift to N gear and engage the handbrake.

What are the methods to deal with rust spots on car paint?

After wiping off the rust spots, you can use a fine needle or toothpick to apply matching paint, or use a touch-up pen. It is recommended to go to a 4S shop for touch-up and polishing treatment. Polishing: The coarseness of the polishing wax used depends on the degree of oxidation of the car paint. If the particles of the sand wax are relatively coarse, it is suitable for grinding off deeper scratches, but it causes greater damage to the car paint. Although polishing has a relatively obvious effect, it should not be used frequently. Frequent polishing of the car will thin the car paint, directly affecting the service life of the car paint surface. Touch-up pen: Although the touch-up pen cannot remove the rust spots on the car paint, it can cover the rust spots to some extent. It can be said to treat the symptoms but not the root cause. It can be used for emergencies, but it is also necessary to clean the vehicle in time to prevent rust spots on the car paint surface.
