What are the uses of motor vehicle safety devices?

Common knowledge about main safety devices of motor vehicles: 1. The speedometer consists of two parts: the speed indicator and the odometer, with the speed indicator showing the driving speed. 2. The oil pressure gauge is used to indicate the lubricating oil pressure in the main oil passage of the lubrication system when the engine is running. 3. The main function of the seat headrest is to protect the cervical spine in the event of a rear-end collision. Adjust the height of the headrest so that the center of the headrest is level with the head. When adjusting the seat, the driver should set it to a position where the clutch pedal and brake pedal can be easily fully depressed. 4. Before driving on the road, fasten the seat belt, whose main purpose is to effectively protect the body in the event of a collision or emergency braking. In vehicles equipped with airbags, front-seat passengers should also wear seat belts. 5. Before driving, check whether the vehicle's steering mechanism, tires, lighting signals, brakes, and other devices are in good condition.

I've been driving for over 20 years, and seat belts are the most basic tool. You must buckle up as soon as you get in the car—they keep you secured in your seat and reduce the risk of being thrown out in case of a crash. Airbags are also crucial, as they instantly deploy during a severe collision to cushion the impact. However, avoid placing phones or decorations on the front dashboard to prevent obstructing their function. The ABS (Anti-lock Braking System) prevents wheel lock-up during rainy conditions or emergency braking, helping maintain steering control. I once relied on it to avoid an accident on a slippery road. When children are in the car, a properly installed child safety seat is a must to minimize injury from bumps. I also regularly check these safety features—like ensuring the seat belt buckles operate smoothly and the airbag warning light isn’t on—because making it a habit is what truly ensures protection.

How long can a license plate be retained under one's name?

It can be retained for at least two years. The following are the conditions that must be met to retain it for at least two years: 1. The license plate must be under one's own name: License plates cannot be traded, so a personal license plate can only be retained under one's own name. Additionally, the plate must have been used for at least one year. In other words, if you buy a car and the license plate is only registered for a few months before selling the car, and the plate has not been registered under your name for a full year, the plate will not be retained. It must be registered for a full year before the license plate can be used again. 2. Strict time limits apply: Previously, the maximum retention period was one year. However, for plates registered after July 2019, if they have been registered for one year, they can be retained for two years. This means that if the car is sold or transferred, the license plate will be automatically retained under the owner's name for two years. During this period, if the owner purchases a new or used car, they can directly register the retained plate, as long as it is within the two-year timeframe, and the owner can choose to use the same plate number again.

What are the differences between the 2017 Tesla Model S and the 2019 version?

The differences between the Tesla Model 3 and Model S mainly lie in body dimensions, motor types, and driving range. Here are the specific details: 1. Body Dimensions: The Tesla Model 3 measures 4694/1850/1443mm, with both front and rear track widths at 1580mm. The Model S measures 4979/1964/1445mm, with a front track width of 1662mm and a rear track width of 1700mm. 2. Motor Types and Driving Range: (1) The Model 3 Standard Range Rear-Wheel Drive Upgrade and Long Range Rear-Wheel Drive versions both feature a permanent magnet/synchronous rear-mounted single motor. The Standard Range version is equipped with an LFP (Lithium Iron Phosphate) battery pack from CATL, with an official range of 468km. The Long Range version uses a ternary lithium battery pack, offering an official range of up to 668km. Both versions have a maximum power output of 202 kW and a maximum torque of 404 Nm. (2) The two lower-end Model S versions feature dual motors—front permanent magnet/synchronous and rear AC/induction—also powered by ternary lithium battery packs. The Long Range Upgrade version delivers a maximum power of 487 kW and a maximum torque of 844 Nm, with an official range of up to 719km.

What are the reasons for loud engine noise in the Octavia?

Here are the reasons for loud engine noise in the Octavia: 1. Incompatibility with the viscosity of new engine oil. After prolonged use, the engine oil becomes thinner, and carbon deposits accumulate. When new oil is replaced, the engine may not adapt to the oil's viscosity, potentially increasing the RPM and causing loud engine noise. High-quality engine oil should be used. 2. Poor sound insulation. If the sound insulation is ineffective, the car's sealing strips should be inspected. If the sealing strips are found to be aged, they need to be replaced. 3. Insufficient coolant. In low temperatures, insufficient coolant can lead to louder engine noise. The coolant level should be checked promptly and refilled if necessary. 4. Abnormal shock absorbers. Issues with the car's shock absorbers can easily cause louder engine noise. Drivers should regularly check the shock absorbers to avoid malfunctions. Professional maintenance at a repair shop is recommended.

Why Does the Civic Experience Engine Oil Dilution?

The reasons for engine oil dilution in the Honda Civic are as follows: 1. During engine startup, excessive fuel is injected, which fails to combust completely due to over-injection. The high pressure on the cylinder walls forces fuel into the crankcase. 2. Normally, fuel would evaporate once the engine reaches operating temperature. However, frequent cold starts and cold weather conditions prevent the oil from warming up sufficiently, making it difficult for the fuel to evaporate. This leads to a continuous increase in engine oil volume. Below are the hazards associated with engine oil dilution in the Honda Civic: Standard engine oil uses viscous oil to maintain lubrication for the engine. However, when the oil becomes diluted by mixing with un-evaporated fuel, its lubricating properties deteriorate, and sealing effectiveness decreases. This allows contaminants to enter. Some emulsification phenomena occur due to diluted oil reducing sealing performance, permitting incompatible substances like water to enter, which can cause severe engine wear.

How to Replace the Key Battery for an Audi Car?

Audi car key battery replacement steps are as follows: 1. Before replacing the key battery, it is necessary to first understand the battery model of the car key. Generally, you can check it in the vehicle user manual and select a new key battery according to the specified model. 2. Press the switch on the metal part of the key back. While pressing the switch, pull the metal part outward to remove the hidden mechanical key. 3. After removing the mechanical key, you can see the internal structure of the original metal part. There are two clips on both the front and back sides. Press them simultaneously and pull outward. 4. Once removed, you can replace the new battery. Be careful not to reverse the positive and negative poles. The installation steps are the reverse of the disassembly sequence.

Does Low RPM Affect the Haval M6 Vehicle?

Low RPM does affect the Haval M6 vehicle. Insufficient RPM means inadequate power, leading to gear dragging and putting the entire transmission system in an abnormal state. The impacts of low RPM are as follows: 1. Due to weak low-end torque, the Haval M6 is prone to stalling during hill starts. To avoid stalling, drivers often start by spinning the tires, but this triggers the ESP system to intervene and cut fuel supply, causing the vehicle to stall directly and making hill starts difficult. 2. The Haval M6's turbo does not engage until 2200 RPM, resulting in very weak power output. Even after turbo engagement, the maximum RPM only reaches 4500. The combination of weak low-end and high-end torque inevitably leads to difficult starts and sluggish acceleration.
