What to Do If a New Car Has Quality Issues?

Is the engine of the Bestune T99 domestically produced or imported?

The engine of the Bestune T99 is domestically produced. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, and electric motors. Engines can be used as power generation devices or refer to the entire machine including the power unit. Taking the Bestune T99 2021 20TD Automatic Captain Edition as an example, its body dimensions are 4800mm in length, 1915mm in width, and 1685mm in height, with a wheelbase of 2870mm. It is equipped with a 2.0T turbocharged engine and a 6-speed automatic manual transmission.

Which Gear is the Low Gear?

Low gear and high gear are relative concepts without unified definitions. In China, based on road conditions, it is customary to refer to first, second, third gears and reverse gear as low gears, while gears above fourth gear are called high gears. Here is relevant information: 1. Waterlogged roads: When driving through waterlogged sections, promptly shift to a low gear and press the accelerator pedal deeply to maintain high engine RPM and torque while passing through the waterlogged area. This reduces the risk of wheel slippage, prevents water from backflowing into the exhaust pipe, and ensures the vehicle has sufficient power to overcome the resistance of the water and underwater obstacles. [3] 2. Bumpy roads: When driving on uneven or potholed roads, using a low gear at idle speed or with slight acceleration can minimize the impact from the rough surface and reduce body vibrations. 3. Speed-limited roads: In areas with low speed limits, such as military zones or residential areas, using a low gear helps avoid excessive speed from continuous acceleration. Even if the accelerator is mistakenly pressed, the speed generally remains comparable to that of a fast-pedaled bicycle. When leisurely driving or sightseeing, a low gear can also enable slow coasting, reducing the burden of driving.

What Are the Characteristics of Mass Communication?

Mass communication is characterized by organization, openness in content dissemination, selectivity, rapidity, and more. Below are some related expanded materials: 1. Mass Communication: It refers to the entire process of social practice activities in which social media organizations publicly transmit information they have replicated through various means to the general public via mass communication media such as text (newspapers, magazines, books), radio waves (broadcasting, television), films, and electronic networks. 2. Selectivity: Firstly, communication tools have a certain degree of selection for the audience; secondly, the audience has a certain degree of selection for communication tools—factors such as age, gender, occupation, cultural literacy, and personal interests can divide the audience into different reader, listener, or viewer groups who may prefer certain communication tools; thirdly, the audience can freely choose the content of the communication; fourthly, the audience can freely choose the time to participate in mass communication. The selectivity of the audience indicates that mass communication does not necessarily mean communication to everyone.

Where is the water on the car floor leaking from?

Water on the car floor is caused by two reasons: 1. Water produced during the operation of the vehicle's air conditioning system, which flows into the car due to a blocked air conditioning drain pipe. 2. External water accumulation entering the vehicle due to clogged sunroof drain pipes. In such cases, the affected parts need to be disassembled, dried, and treated. Additional information about water on the floor: 1. Impact: If left untreated for a long time, water on the floor can cause rusting, severe cases may lead to rotting, affect the vehicle's speed limiter in the chassis area, impair normal driving operation, and even create safety hazards. Therefore, timely treatment is essential. 2. How to protect the vehicle floor: The vehicle floor can be protected using full-coverage floor mats, which effectively safeguard the floor. Especially during seasonal use, it's necessary to regularly check the sunroof drain outlets, air conditioning drain outlets, and door drain holes to prevent water ingress caused by blockages.

How much electricity does an electric vehicle consume per 100 kilometers?

Generally, electric vehicles consume 10-15 kWh of electricity per 100 kilometers. Below is relevant information about electric vehicles: 1. Advantages: They do not emit harmful gases that pollute the atmosphere. Even when converting the electricity consumption to emissions from power plants, pollutants other than sulfur and particulates are significantly reduced. Since power plants are mostly located far from densely populated cities, the harm to humans is minimized. Electricity can be generated from various primary energy sources, such as coal, nuclear power, and hydro power, alleviating concerns about the depletion of petroleum resources. Electric vehicles can also take advantage of surplus electricity during off-peak hours at night for charging, allowing power generation equipment to be fully utilized around the clock, greatly improving economic efficiency. 2. Characteristics: Simple structure and easy maintenance. Electric vehicles have a simpler structure compared to internal combustion engine vehicles, with fewer moving and transmission parts, resulting in less maintenance work. However, they have higher power costs and shorter driving ranges.

Why Does the Window Make Continuous Noise When Raised to the Top?

Continuous noise when the window is raised to the top may be due to insufficient lubrication or malfunction of the lifting motor. Spraying liquid butter along the rubber seal can improve the situation, but it is recommended to have it checked and replaced at a professional facility. Additional information about automotive glass is as follows: 1. Tempered Glass: Automotive glass is manufactured by heating the glass to near its softening point in a furnace, then rapidly transferring it to fans with varying cooling intensities for uneven cooling. This process creates different stress levels between the main viewing area and the peripheral regions, producing zone-tempered glass. 2. Classification: Automotive glass is an essential component of vehicle body attachments, primarily serving a protective function. There are three main types: laminated glass, tempered glass, and zone-tempered glass, all of which can withstand significant impact forces. 3. Function: Most front windshields are made of laminated glass, which consists of three layers. The middle layer is highly resilient and adhesive, ensuring that the inner and outer layers remain bonded to it upon impact, reducing the risk of injury. Vehicles may use soundproof glass in the front, rear, or throughout the entire cabin. Soundproof glass is a product designed to block sound, typically featuring a double or multi-layer composite structure of laminated glass. The sound-damping adhesive (film) in the middle layer plays a crucial role in weakening and attenuating sound transmission.
