What is the principle of a dual-clutch transmission in cars?

The principle of a dual-clutch transmission in cars is: A dual-clutch transmission has two clutches, one responsible for the odd-numbered gears (1st, 3rd, 5th, 7th), and the other clutch responsible for the even-numbered gears (2nd, 4th, 6th). It combines the functions of two manual transmissions into a single system, without a torque converter or planetary gear sets. The advantages of a dual-clutch transmission include: 1. Fast gear shifting: The gear shifting time of a dual-clutch transmission is very short; 2. Fuel efficiency: Because it eliminates torque interruption, meaning the engine's power is continuously utilized and always operates at optimal conditions, it can significantly save fuel; 3. Comfort: Due to the fast shifting speed, each gear shift in a DCT is very smooth; 4. There is almost no torque loss during the gear shifting process.

What does the bulb exclamation mark mean when it appears on the car?

Yellow bulb with an exclamation mark is the lighting fault indicator, indicating that there is a fault with the car lights. Solution: Go to a 4S shop for inspection and treatment as soon as possible, or you can check it yourself. Focus on checking commonly used bulbs such as turn signals, fog lights, and interior lighting to see where the problem is. The exclamation mark is a common fault prompt in cars. In addition to the yellow bulb with an exclamation mark, there are four other forms of exclamation marks: an exclamation mark inside a triangle, an exclamation mark inside a yellow gear, an exclamation mark in the middle of a bracket circle, and an exclamation mark in the middle of a bracket with a horizontal line below. Here is a detailed analysis: General fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates that the car's general performance or components and functions have malfunctioned. Mainly includes parking sensor failure, fuel cut-off system intervention or failure, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to a 4S shop for inspection to find out the source of the fault. Automatic transmission fault: An exclamation mark inside a yellow gear. This is the automatic transmission fault warning light, indicating that there is a fault with the transmission or the transmission lubricating oil is below the normal range. The transmission oil needs to be replaced in time. Brake system fault: An exclamation mark in the middle of a bracket circle. This represents a warning of the brake system, mainly including brake system failure and low brake fluid level. The brake system needs to be inspected immediately to avoid accidents. Tire pressure abnormality: An exclamation mark in the middle of a bracket with a horizontal line below. This represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will come on. Check the car's tire pressure and restore it to the normal range.

What is the bolt pattern for BMW 3 Series wheels?

The bolt pattern for BMW 3 Series wheels is 5×120, and the wheel sizes for BMW 3 Series are 16 and 17 inches. Below are the daily inspection items for BMW 3 Series tires: 1. Check tire pressure: Ensure the tire pressure of all tires (including the spare) meets the specified value. The manufacturer provides the standard tire pressure for the vehicle model. Check at least once a month, and especially before and after long-distance or high-speed driving. 2. Check tire wear condition: This includes whether the tires are wearing normally down to the wear indicators and if there is uneven wear. For tires with severe abnormal wear, promptly identify the cause and replace the tire. 3. Check for debris between treads: If present, it's best to remove the debris, as leaving these embedded objects between treads for a long time can damage the tires.

Does Insurance Take Effect on the Day of Vehicle Pickup?

In the "Notice on Strengthening the Management of Compulsory Traffic Insurance Underwriting," it has been clearly stipulated that compulsory traffic insurance takes effect immediately upon purchase and does not require waiting until the next day. However, the effective time of commercial insurance is determined by the insurance company, as commercial insurance is an additional type of insurance offered by insurance companies and is not a mandatory national vehicle insurance. Below is a partial introduction to auto insurance: 1. Components: Auto insurance generally includes two parts: basic insurance and additional insurance. Basic insurance is further divided into vehicle damage insurance and third-party liability insurance. 2. Coverage: Vehicle damage insurance compensates for the loss of the insured vehicle; third-party liability insurance compensates for targets outside the insured vehicle, such as people and public property hit, the other party's car, etc.; passenger liability insurance compensates for the loss of people and property inside the insured vehicle; theft insurance compensates for the theft of the insured vehicle; no-deductible coverage ensures 100% compensation in case of an accident. If no-deductible coverage is not purchased, the policyholder bears 30% of the deductible for each accident.

How many years can car antifreeze generally last?

Car antifreeze can generally last for two years, while some long-life antifreeze can have a shelf life of up to 5 years. Antifreeze that exceeds its shelf life may deteriorate, produce impurities, and some of its internal chemical components may become ineffective, which can have a certain degree of impact on the cooling system or engine, making it unusable. The full name of car antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze function, which can prevent the coolant from freezing and cracking the radiator or freezing the engine cylinder block or head when the car is parked in cold winter. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems, with excellent properties such as antifreeze in winter, anti-boil in summer, and anti-scale and anti-corrosion all year round.
