What is the small light below the car headlight called?

The small light below the car headlight is called the fog light. Here is an introduction to fog lights: 1. Turning on fog lights: After turning on the parking lights, you can then turn on the fog lights. The front fog lights can be turned on individually, while the rear fog lights can only be turned on together with the front fog lights and cannot be activated separately. There are two main styles of fog light switches: button-type and rotary-type. Different car manufacturers have their preferred methods for turning on fog lights. 2. Function of fog lights: In conditions of poor visibility such as foggy or rainy weather, fog lights help other vehicles see your car. Therefore, fog light sources need to have strong penetration. Most vehicles use halogen fog lights, while more advanced models may feature LED fog lights. Fog lights must be installed below the bumper, at the position closest to the ground on the car body, to ensure their effectiveness. If installed too high, the light cannot penetrate the rain or fog to illuminate the road (as fog is generally thinner below 1 meter in height), which could easily lead to dangerous situations.

Which came first, traffic lights or cars?

Traffic lights existed before cars in the world. The first traffic light in the world appeared in Parliament Square, London, UK, and was installed in 1868. The first car in the world was created by Karl Benz from Germany, and it appeared in 1886. About Karl Benz: Mr. Karl Benz was the creator of the automobile, and later he founded an automobile manufacturing company, which is Mercedes-Benz. About Mercedes-Benz: Mercedes-Benz is a luxury car manufacturer from Germany, and it is also the inventor of the automobile. Mercedes-Benz has many luxury SUVs and sedans, as well as high-performance models. The top luxury sedan from Mercedes-Benz is the S-Class, a large luxury sedan that competes with models like the BMW 7 Series and Audi A8L. The new S-Class has a wheelbase of 3165 mm, with length, width, and height measuring 5259 mm, 1899 mm, and 1497 mm, respectively. About the engines of the new Mercedes-Benz S-Class: The new S-Class uses two engines, one being a low-power 3.0-liter turbocharged engine and the other a high-power 3.0-liter turbocharged engine. (1) The low-power 3.0-liter turbocharged engine produces 299 horsepower and a maximum torque of 420 Nm. (2) The high-power 3.0-liter turbocharged engine produces 367 horsepower and a maximum torque of 500 Nm.

Are There Right-Hand Drive Cars in China?

China does have right-hand drive cars, particularly in Hong Kong where all vehicles are right-hand drive (abbreviated as RHD). However, mainland China currently does not have right-hand drive cars. About left-hand and right-hand drive: In right-hand drive cars, the driver sits on the right side, and the car drives on the left side of the road. Conversely, in left-hand drive cars, the driver sits on the left side, and the car drives on the right side of the road. The reason for the difference between left-hand and right-hand drive: The distinction between right-hand and left-hand drive cars primarily arises from different driving practices. In countries where vehicles drive on the left side of the road, the driver's position is on the right. If calculated by road mileage, 28% of the world's drivable roads are left-hand drive. Countries using right-hand drive cars are mainly the UK, Commonwealth countries, and former British colonies.

What are the functions of couplings and clutches? What are the differences between them?

Both couplings and clutches are used to connect shafts (or other moving parts) to transmit motion and torque. They can also serve as safety devices for overload protection. The difference is that couplings generally cannot be disconnected during machine operation and can only be separated after shutdown; whereas clutches can be engaged or disengaged at any time during operation. Couplings can compensate for misalignment between connected parts, such as universal couplings which can transmit motion or torque even when there is a significant angle between the two shafts. Here are detailed introductions to couplings and clutches: 1. Coupling classification: Couplings include sleeve couplings, flange couplings (rigid fixed type); gear couplings (rigid movable type): elastic pin couplings, nylon pin couplings (elastic movable type). Rigid components cannot absorb impact or vibration, while elastic components can absorb impact and vibration; movable and fixed types refer to the ability to compensate for misalignment. 2. Clutch classification: Common clutches are of two types: jaw clutches and friction clutches. Jaw clutches transmit large torque and strictly ensure synchronous rotation of the two shafts, with compact size, but are difficult to engage/disengage. Friction clutches engage smoothly and conveniently, providing safety protection, but cannot guarantee identical rotational speeds of the two shafts.

What is the difference between car primer and topcoat?

Topcoat and primer differ in materials and functions. The differences are: 1. Different main components: Primer consists of four parts: resin, solvent, filler, and additives; while the topcoat is composed of resin, solvent, and additives, with the main difference being that the topcoat contains little or no filler. 2. Different functions: Primer is the first layer of the paint system, mainly used to level and smooth the surface, support the topcoat, provide fullness to the paint, reduce paint costs, and help save energy. The topcoat is the final coating layer, usually applied in multiple layers or thickened to increase the paint film thickness. Additionally, its rich color series makes cars vibrant. The thickness of the coating mainly relies on the primer, while the topcoat primarily serves decorative and protective purposes. The functional differences between primer and topcoat: 1. Functions of the topcoat: It features scratch resistance, gloss hardness, transparency feel, aging resistance, and anti-yellowing properties, all mainly reflected in the topcoat. The quality of the topcoat directly affects the entire paint film's quality. 2. Functions of the primer: (1) Leveling effect: Fills capillary pores in the steel plate, facilitating surface painting. (2) Supports the topcoat: Ensures the topcoat adheres tightly to the car surface. (3) Provides fullness: Due to the many fillers in the primer, it increases paint thickness. (4) Reduces costs and saves energy: Because primer is generally cheaper.

Will parking the car in the opposite direction result in penalty points?

Parking the car in the opposite direction will incur a fine, as it is considered reverse parking. In China, vehicles drive on the right side of the road, so when parking on the roadside, the car should be parked close to the right side of the road. Therefore, if the driver's side door is next to the traffic lane when parking, it is considered forward parking; otherwise, it is reverse parking. Reverse parking is a violation of parking regulations and is essentially driving in the wrong direction. This traffic violation can result in a fine of 200 yuan and 3 penalty points if severe. According to Article 63, Item 5 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": When temporarily parking a motor vehicle on the road, the following regulations must be observed: 1. Roadside parking should be close to the right side of the road: The driver of the motor vehicle must not leave the vehicle and should drive away immediately after passengers get on or off or items are loaded or unloaded; 2. The right edge of the vehicle body should not be more than 0.5 meters from the edge of the road: According to the regulations on parking in the direction of travel, motor vehicles must not park in the opposite direction when temporarily parked. Even if parked within a parking space, parking in the opposite direction is still considered illegal parking.
