In winter, the recommended tire pressure for small cars is between 2.3 to 2.5 bar. Tire pressure refers to the air pressure inside the tires, and its level plays a crucial role in the performance and power of the vehicle. The impacts of low tire pressure are: 1. Increased contact area between the tire and the ground, making the steering wheel heavier and affecting driving; 2. Tires are prone to overheating, increasing the risk of blowouts; 3. Expansion of the tire body, leading to cracks on the inner and outer sides of the tire; 4. Accelerated rubber aging and faster tire wear. The impacts of high tire pressure are: 1. Increased friction between the tire and the ground, reducing tire grip; 2. Impaired braking effectiveness and driving comfort, with accelerated wear on the central tread pattern, shortening tire lifespan; 3. Increased body vibration, accelerated tire aging, reduced wear resistance, and higher risk of blowouts.

When driving in winter, I think tire pressure needs attention because the low temperature causes air to contract, making tire pressure prone to drop. For passenger cars, the recommended tire pressure is generally between 2.2 and 2.5 bar, depending on your specific car model—usually indicated on a small label on the driver's door frame. When I first started driving, I didn’t pay attention to this, and as a result, my tires wore out faster in winter, and fuel consumption increased. So now, I make it a habit to check once a week with a digital tire pressure gauge, measuring when the car has been parked overnight in a cold state for the most accurate reading. Too low pressure can lead to unstable steering and increased slipping on snowy roads; too high pressure makes the tires stiff and uncomfortable, causing a bumpy ride. In winter, when roads are frozen and slippery, proper tire pressure enhances grip and reduces accident risks. Regular checks are simple yet effective, saving fuel and ensuring safety.

Why Shouldn't High Beams Be Used When Following Another Vehicle?

The reason high beams should not be used when following another vehicle is that they can easily blind the driver ahead, increasing the risk of traffic accidents. Here is an introduction to automotive safety-related content: Vehicle Overview: Automotive safety is primarily divided into two major aspects - active safety and passive safety. Active safety refers to the ability to control the vehicle as smoothly as possible. Whether braking or accelerating in a straight line or steering left and right, the operations should be as smooth as possible to avoid deviating from the intended path and not affecting the driver's visibility or comfort. Other Safety Issues: The scope of automotive safety technology is becoming broader and more detailed, developing towards integration, intelligence, systematization, and universal participation. Strictly controlling speed during nighttime driving is a fundamental measure to ensure safety.

What is a car's three-way catalytic converter?

The three-way catalytic converter is the most important external purification device installed in a car's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Cleaning the three-way catalytic converter: The cleaning method for the three-way catalytic converter is the drip-feed method. This involves connecting a plastic hose to the engine's vacuum solenoid valve and using the air pressure in the hollow tube to draw the cleaning agent from the infusion bottle into the engine. As the cleaning agent exits through the exhaust pipe, it cleans the three-way catalytic converter. Lifespan of the three-way catalytic converter: The lifespan of a three-way catalytic converter is generally between 80,000 to 100,000 kilometers. The specific lifespan depends on the vehicle's usage conditions, as well as the quality of fuel used and the driving environment.

What car series does Buick belong to?

Buick belongs to the American car series. The following is a detailed introduction to the Buick car series: 1. The Buick BUICK brand began in 1900. In the United States, Scotsman David Dunbar Buick and his chief engineer Walter L. Marr left their long-time boat engine and agricultural machinery repair business to start manufacturing the first experimental car (when carriages were the main means of transportation). In 1903, they established the Buick BUICK Motor Company. A year later, car production officially began, with the first batch of 37 cars put on the market for sale. 2. Buick's famous "Three Shields" logo is based on a circle containing three shields. Its origin can be directly traced back to the family crest of David Dunbar Buick, a Scotsman and founder of the automobile manufacturing industry.

What kind of glue is used to repair car taillight cracks?

For repairing car taillight cracks, the following two types of glue can be used: 1. Silicone glass glue: Single-component silicone glass glue is a paste-like material that solidifies into a tough rubber-like solid upon contact with moisture in the air. Silicone glass glue has strong adhesion, high tensile strength, and also features weather resistance, vibration resistance, moisture resistance, odor resistance, and adaptability to large temperature variations. With its wide applicability, it can bond most building material products. 2. Epoxy resin adhesive: Epoxy adhesives mainly consist of two components: epoxy resin and a curing agent. To improve certain properties and meet different applications, auxiliary materials such as toughening agents, diluents, accelerators, and coupling agents can be added.

What are the symptoms of a faulty ignition switch?

Since the ignition switch controls the activation and deactivation of the ignition coil, if the ignition switch malfunctions, the vehicle will not start normally. The most direct manifestations include failure to ignite, inability to turn off the engine, unexplained stalling, or even the malfunction of circuits controlled by the key. Below is an introduction to the ignition switch: The ignition switch is the most crucial switch in a car's electrical system, serving as the control hub for various circuit branches. It can freely activate or deactivate the ignition coil and has four positions: START, ON, ACC, and LOCK. Its primary functions include locking the steering wheel shaft (Lock), turning on the ignition and instrument indicators (ON or IG), the start position (ST or Start), and the accessory position (Acc, mainly for the radio). For diesel vehicles, an additional (HEAT) position is included.
