Currently, there are four main types of new energy vehicles: hybrid electric vehicles (HEVs), pure electric vehicles (BEVs), fuel cell electric vehicles (FCEVs), and other new energy vehicles. New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new onboard power devices), integrating advanced technologies in vehicle power control and driving systems, resulting in vehicles with advanced technical principles, new technologies, and innovative structures. Taking the BYD Song as an example, this vehicle is positioned as a new energy compact SUV, equipped with a 1.5T turbocharged gasoline engine, paired with two electric motors, matched with a DCT dual-clutch transmission, and featuring an advanced electric four-wheel-drive system.

What are the benefits of waxing a car?

Waxing a car has the following benefits: 1. It makes it difficult for rainwater to adhere to the car's surface, preventing acid rain from corroding the paint; 2. The thin layer formed by waxing can reflect light, avoiding paint aging; 3. It can prevent the generation of static electricity and reduce the adhesion of charged dust to the car; 4. It serves as a polishing agent, enhancing the brightness of the paint and making the car appear newer. As a traditional item in car detailing, the primary function of car waxing is waterproofing and protection against acid rain. Due to the protection provided by the wax, the amount of water droplets adhering to the car body is significantly reduced. Wax application can be divided into manual waxing and mechanical waxing. Manual waxing is simple and easy to perform, while mechanical waxing is more efficient. Whether done manually or mechanically, it is essential to ensure even application on the paint surface.

What causes a clicking sound when turning the steering wheel?

The reasons for a clicking sound when turning the steering wheel: 1. Friction noise from the steering wheel horn electrode; 2. Noise from the steering column universal joint or the steering column rubbing against the floor mat; 3. Noise from the steering wheel return lever. The friction noise from the steering wheel horn electrode is more common in vehicles without airbags, where the steering wheel only has a horn button. Since the horn switch rotates with the steering wheel while the connecting wire below remains stationary, the wire can easily break when turning the steering wheel. Noise from the steering column universal joint or the steering column rubbing against the floor mat occurs because the front end of the steering column has a universal joint. Sometimes, lack of lubrication in the universal joint can cause a clicking sound, in which case the universal joint needs to be lubricated. The turn signal has an automatic return function. When the turn signal is on and the steering wheel is turned, the steering column hitting the return lever can produce a clicking sound.

What does a circle with three dots outside represent?

When a car's instrument panel displays a circle with three arrows pointing towards it, this is the vacuum warning indicator light. Below is relevant information: 1. Main reasons for vacuum warning light illumination: When the ignition switch is turned to the ON position, this light should illuminate. When turned to the START position, it should turn off, which is normal. If this indicator light doesn't turn off, it may be caused by air leakage in the vacuum tube. In this case, braking may be dangerous, and it's not recommended to continue driving. Contact the nearest service station for inspection. 2. Indicator light names and corresponding symbols: Brake warning light; symbol is a red "!" inside a circle. Anti-lock braking system (ABS) warning light; symbol is the yellow "ABS" text inside a circle.

Specification model representation: Tires are important components of a car, and there are many specification models of tires, with different models suitable for different types of vehicles. The specification model identification is usually on the side of the tire, represented by a series of alphanumeric characters, corresponding to the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. 2. Speed rating: Based on the different maximum speeds they can withstand, tire speed ratings can be divided into different grades from A to Z, with grade A further subdivided into eight different levels from A1 to A8. The further back the letter representing the tire speed rating is, the better the tire performance.
