What are the causes of abnormal noises in a car?

There are several reasons that may cause abnormal noises in a car: 1. Long service life of the engine: Some cars have engines that have been used for too long, and high idle speed during each startup may cause abnormal noises. 2. The engine oil used during maintenance is also a contributing factor: Expensive engine oil is not necessarily the best; it must be suitable for your car. Unsuitable engine oil can produce certain abnormal noises. 3. Belt wear: Cars with long service lives may need belt replacements, and worn belts can also produce such noises.

Does the Auto Start-Stop Function Really Harm the Car?

The auto start-stop function does not harm the car. Below is a detailed introduction to the auto start-stop technology: 1. The start-stop function only stops the engine from working, but the oil system does not stop. This means that although the engine is not rotating, the oil will still flow inside the engine, ensuring better lubrication and protection for the engine when the car starts again. 2. The auto start-stop technology is a system that can automatically control the engine shutdown and ignition, known in English as STOP&START, abbreviated as STT. Vehicles equipped with auto start-stop technology will automatically shut down the engine when temporarily stopping during driving. When it is time to move forward again, the system will automatically restart the engine. Generally, the auto start-stop function is enabled by default in vehicles, but owners can choose to turn it off if they don't need it. 3. The advantage of the auto start-stop technology is fuel savings. Whether waiting at a red light or stuck in traffic, the auto start-stop technology can automatically turn off the engine when the car stops, thereby saving fuel. However, the cost of using the car will increase. Cars with an auto start-stop system are several thousand dollars more expensive than those without. Additionally, due to the frequent starting and stopping of the engine, there is a higher demand for oil quality, further increasing maintenance costs.

The Role of Twin-Turbocharging?

The role of twin-turbocharging is to address the traditional turbo lag phenomenon. Below are precautions for using turbocharged engines: 1. Choose full synthetic oil: Due to the high temperature and high-speed operation of turbocharged engines, the requirements for oil's high-temperature shear resistance and low-temperature fluidity are quite high, and there are also relatively high demands on the oil film. Therefore, it is necessary to select full synthetic oil and reasonably choose the oil viscosity. 2. Use high-quality fuel whenever possible: Turbocharged engines should preferably use high-quality fuel. Since turbocharged engines are mostly direct-injection, which has higher requirements for fuel quality, this can help avoid carbon buildup during use.

Do You Need to Lift Off the Throttle When Using Paddle Shifters?

Paddle shifters require lifting off the throttle. As a quick shifting method, paddle shifters enhance driving operability. Typically located behind the steering wheel, operating paddle shifters usually only requires shifting the gear into D mode, S mode, or manual mode. Common misconceptions about paddle shifters: 1. Paddle shifters are not necessarily functional only in manual mode; 2. The design and operation of paddle shifters may vary across different car models—some move with the steering wheel while others remain stationary; 3. Some vehicles' ECUs may intervene to protect the engine and transmission by preventing abnormal shifting behaviors.

How to Match a Tire Pressure Monitor?

The method for matching a tire pressure monitoring sensor is as follows: Specialized computer software is required for the matching process. The replaced tire pressure monitor has a new identification number, which needs to be re-entered and matched in the computer software. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver in case of tire leaks or low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other tires. By comparing the rotational speed differences between the tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Introduction: This system combines the advantages of both the above systems. It is equipped with direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to a full direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a direct system.

When will the NIO 150kWh battery pack be launched?

NIO's 150kWh battery pack is planned to be released by the end of 2022. Here are detailed advantages of the battery pack: 1. Replacing liquid electrolytes with solid-state electrolytes: Significantly reduces thermal runaway risks. 2. Electrochemical window: Can reach above 5V, higher than liquid lithium batteries (4.2V), allowing compatibility with high-energy cathodes and lithium metal anodes, greatly improving theoretical energy density. 3. Solid-state batteries can simplify packaging and cooling systems: Further reducing battery weight in limited spaces, with volumetric energy density increasing by over 70% compared to liquid lithium batteries (graphite anode), reaching 500Wh/kg.
