What is Automotive Brake Fluid?

Automotive brake fluid is the liquid used in hydraulic braking systems. More information about automotive brake fluid is as follows: 1. After prolonged use, the brake pump will exhibit varying degrees of wear. 2. Automotive brake fluid does not undergo chemical reactions, is unaffected by high temperatures, and will not corrode, soften, or cause expansion to metals and rubber. 3. When replacing brake fluid, it is important to note the replacement cycle, which varies depending on different climatic conditions. 4. During replacement, it is essential to use brake fluid of the same grade as originally specified for the vehicle, and brake fluids from different brands should not be mixed.

Can a puncture on the sidewall of a tire be repaired?

Tire sidewall punctures can be repaired if the radial length of the scratch is less than 5cm and the axial length is less than 0.5cm. Generally, if more than three layers of the tire sidewall cord fabric are broken, it is not recommended to repair it as it may affect driving safety. If the number of broken cord fabric layers is three or fewer, the tire can still be repaired. Below is some relevant information about car tires: 1. Most car tires are radial tires, primarily composed of cord fabric layers and rubber. The cord fabric layers consist of horizontal and vertical cord threads (some may include steel wire mesh), which mainly bear the load, while the rubber provides sealing and flexible deformation functions. 2. When a tire is punctured and leaks air, it is usually due to damage to the tire's inner liner, which can be repaired. However, if the cord fabric layers are damaged, it directly affects the tire's strength. The more cord threads that are broken, the greater the risk of a blowout. Similarly, if the inner cord threads of the tire are not broken, the tire can still be used normally after restoring its airtightness.

How to Check the Production Date of Glass

The production date of automotive glass is usually marked at the lower right corner of the window or below the logo. It is presented in the form of a single digit. The markings on the glass can provide information about the brand, structure, specifications, and production date of the glass. There are two main types of production date markings for automotive glass: The first type: Number + small black dots: The number represents the last digit of the production year. If the small black dots are in front of the number, subtract the number of dots from 7 to get the production month. If the small black dots are behind the number, subtract the number of dots from 13 to get the production month. The second type: Number + small and large black dots: This representation is relatively simpler. The leading number represents the last digit of the production year, the small black dots represent the quarter, and the large black dots represent the month within that quarter. However, some cars are special, such as BMW, whose glass does not use the above two methods (some imported models also follow this pattern). If you want to know the production date of such automotive glass, you need to enter the serial code on the glass and query it through a website, which is relatively more complicated.

What is the difference between a sedan and a hatchback?

The differences between a hatchback and a sedan: 1. The most obvious difference is the styling—the presence or absence of a "rear end" is what distinguishes a hatchback from a sedan. 2. A hatchback refers to a car body that has a rear luggage compartment but does not protrude from the main body. In reality, the passenger compartment and the rear luggage compartment are integrated, only separated by the rear seats. 3. A sedan is typically referred to as a car with both a front and a rear. Structurally, if the car's engine compartment, passenger compartment, and rear luggage compartment are all completely separated and this separation is fixed and irreversible, then it should be considered a sedan. 4. Hatchbacks are generally more expensive than sedans. The higher price of hatchbacks is due to their consistent design direction, different brand positioning, and a consistently good reputation. Their superior craftsmanship, engine, chassis, handling, etc., are better than those of sedans. 5. Hatchbacks are more compact in size than sedans, making them more flexible and easier to park. Hatchbacks appear more stylish and are practical enough. If the second-row seats can be folded down, they can provide a significant amount of additional cargo space. Hatchbacks also offer better fuel efficiency compared to sedans.

What is the difference between installing an automatic transmission and a manual transmission?

Introduction to the differences between automatic and manual transmissions: 1. Different principles. 1. Manual transmission: The driver manually shifts the gear lever (shift knob) to change the gear meshing position inside the transmission, altering the gear ratio to achieve speed variation. 2. Automatic transmission: While driving, the driver operates the accelerator pedal as needed, and the automatic transmission automatically shifts into different gears based on engine load and vehicle operating conditions, adjusting gear changes according to vehicle speed and engine RPM. 2. Different characteristics. 1. Manual transmission: Stable performance, high transmission efficiency, and high fuel utilization. 2. Automatic transmission: Convenient operation with flexible gear ratios. There are various types, including hydraulic automatic transmissions, mechanical continuously variable transmissions (CVT), electronically controlled mechanical automatic transmissions, and dual-clutch automatic transmissions. The transmission is connected to the engine via a clutch, allowing the transmission's input shaft to synchronize with the engine's RPM. 3. Transmission efficiency. Differences exist because manual transmissions rely entirely on mechanical transmission, whereas automatic transmissions use hydraulic transmission via a torque converter, leading to variations in operational efficiency and resulting in differences in fuel consumption. For vehicles of the same brand and displacement, manual transmissions can save approximately 10% more fuel compared to automatic transmissions.

How to Fix the Engine Malfunction Light?

If the engine malfunction light is on, you can follow these steps to address the issue: First, check if the engine is running normally and whether there are issues such as shaking or emitting black smoke. If any of these problems exist, avoid restarting the engine. Specifically, do not restart the engine if the red light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the car key halfway to the 'on' position without depressing the clutch. The car will perform a self-check after powering on. Wait for 5-10 seconds and observe whether the malfunction light on the dashboard turns off. If the malfunction light remains on, visit a service center as soon as possible to diagnose the issue. The service center can use a portable diagnostic tool to read the fault code, obtain fault information, and perform targeted repairs. The engine malfunction light is an icon resembling a water tap. It comes in two colors: yellow and red. A yellow light indicates a warning, while a red light signifies a prohibition. When the yellow malfunction light is on, it means certain system parameters in the car may have exceeded the set range. The car can still be driven, but some functions may be limited. When the red malfunction light is on, the car must be stopped immediately, the engine turned off, and driving prohibited until the fault is checked. Common causes for the engine malfunction light to illuminate include: sensor failure, fuel quality issues, poor combustion of the air-fuel mixture, turbocharging problems, intake issues, exhaust problems, and anti-theft system malfunctions.
