Buick Excelle does have an external circulation mode, with the internal and external circulation sharing the same button. Related information: 1. Introduction: External circulation refers to heating or cooling the air outside the vehicle before introducing it into the cabin, facilitating gas exchange between the interior and exterior. 2. Expansion: The Buick Excelle is equipped with the latest third-generation small-displacement inline 4-cylinder DVVT-Ecotec engine, paired with a 5-speed manual transmission or a 6-speed automatic manual transmission. It offers three displacement options: 1.6L, 1.8L, and 1.6T. The 1.6T model features the same engine used in the Buick Regal 1.6T, delivering a maximum power of 132KW and a maximum torque of 230N·m, with performance comparable to a mid-to-high-end car's 2.4L naturally aspirated engine.

How many points are deducted for eating while driving?

Eating while driving results in a 2-point deduction. Eating while driving is considered an act that hinders safe driving and will incur a 2-point penalty. The regulations of the Traffic Safety Law and its hazards are as follows: Traffic Safety Law regulations: When driving a motor vehicle, the following behaviors are prohibited: driving when the doors or compartments are not properly closed; hanging or placing items within the front or rear windows of the vehicle that obstruct the driver's view; making or answering handheld phone calls, watching TV, or engaging in any other behavior that hinders safe driving. Hazards of eating while driving: Eating while driving can lead to distraction, and even slowing down may not effectively avoid danger. If it is merely to save time or for convenience, the risks far outweigh the benefits. According to foreign statistics, the risk of accidents increases by 1 times when eating while driving and by 1.5 times when drinking beverages. These behaviors are more dangerous than using a phone while driving, and their hazard level is comparable to drunk driving.

What to Use to Wipe Glass to Prevent Fogging?

You can use dish soap or soapy water to wipe the glass to prevent fogging, because soapy water and dish soap contain surfactants that effectively prevent water vapor from condensing on the surface, thus serving as an anti-fogging measure. Mix dish soap and water in a ratio of approximately 1:10, then use a soft cloth to apply the prepared solution to the inside of the front and rear glass. Wiping it first and letting it dry will enhance the anti-fogging effect. The principle is as follows: 1. The active molecules in dish soap can be divided into two parts: one end is a charged, polar hydrophilic group, and the other end is a non-polar hydrophobic group. 2. The active molecules can disrupt the surface tension of water. When soap molecules enter the water, the polar hydrophilic part breaks the attraction between water molecules, reducing the surface tension of water and allowing water molecules to spread evenly on the treated glass surface, forming a water film that adheres to the glass. 3. The more rainwater hits the glass, the larger the water film becomes, maintaining the glass's high clarity at all times.

Is the small car CVT an automatic transmission?

Automobile CVT is an automatic transmission. CVT belongs to the automatic transmission category, with its full name being Continuously Variable Transmission, which is one of the types of transmissions used in automatic transmission models currently available on the market. The introduction and principles of automatic transmission are as follows: Introduction to automatic transmission: Automatic transmission eliminates the need for manual gear shifting while driving. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Common automatic transmission gears include P, R, N, D, S, and L. Currently, the most widely used transmissions in automatic transmission models on the market include AT (Automatic Transmission), CVT (Continuously Variable Transmission), DCT (Dual Clutch Transmission), and semi-automatic transmissions, each with its own advantages and disadvantages. Manufacturers choose different transmissions based on actual needs. Principles of automatic transmission: Power is transmitted through a chain drive without actual gears, providing drivers with smooth driving performance and good fuel economy.

Can I Get My Car Inspected Without Washing It?

It is possible to get your car inspected without washing it, but it would be better to wash it before the annual inspection. Annual inspection requirements: If the car body is not very clean, it is best to wash it thoroughly. One of the requirements for the annual inspection is that the vehicle's exterior must be clean and tidy, with all lights and instruments intact and functioning properly, and free from illegal modifications or other non-compliant conditions. The vehicle's brakes and handbrake must perform well, and it must be equipped with a valid fire extinguisher and reflective warning triangle. Pre-inspection check: If the car is nearing its maintenance mileage, it is advisable to take it to a 4S dealership for maintenance and a free inspection. This way, the dealership staff will check the engine's condition, as well as the vehicle's lighting and braking systems, among other indicators.

What is the minimum tire pressure for safe driving?

Tire pressure below 1.7 bar is unsafe for driving. Vehicles are typically equipped with tire pressure monitoring systems that trigger an alert when tire pressure falls below 1.8 bar. This threshold is also applicable to tires without pressure sensors, and it's recommended not to go below this value. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and potential alignment issues, compromising driving safety; Excessive movement of tire components results in abnormal heat generation from over-compression; Degrades the functionality of cords and rubber, potentially causing delamination or cord breakage, along with excessive friction against the rim leading to bead area damage and abnormal wear; Multiplies friction between tire and road, causing rapid temperature rise, tire softening, and drastic strength reduction - potentially leading to blowouts during high-speed driving; Increases tire body deformation, making sidewalls prone to cracking while generating excessive heat from flexing, accelerating rubber aging, cord fatigue, and tread shoulder wear.

Which wheel is the problem when a Mercedes-Benz pulls to the right?

Mercedes-Benz pulling to the right is an issue with the right front wheel. Tire issues: Uneven tire pressure on both sides can cause the car to pull towards the side with lower tire pressure. If the tread depth differs between the front wheels, the car will also pull towards the side with shallower tread. Alignment data issues: Incorrect alignment data can also lead to pulling. The vehicle will pull towards the side with a larger camber angle and towards the side with a smaller caster angle. Impact of vehicle pulling: This is a serious and complex issue, mainly caused by imbalance between the left and right sides. When such a problem occurs, it is necessary to adjust the vehicle properly. Otherwise, prolonged driving in this condition will only result in uneven wear of important components like tires, leading to more safety hazards.
