What does the three differential locks in a car mean?

Car three differential locks refer to the front differential lock, central differential lock, and rear differential lock. For off-road vehicles, having these three locks is equivalent to being the king of off-roading. The function of the front differential lock is to ensure that all wheels receive the same power when one side of the vehicle is lifted off the ground, hence the front differential lock is known as the life-saving component of off-road vehicles. The central differential lock ensures that the front and rear wheels rotate at the same speed when wheel slippage occurs, but this is limited to minor road conditions. In cases of cross-axle situations or artillery shell pits, the central differential lock is less effective. The rear differential lock allows the rear wheels to rotate at the same speed as the front axle, specifically when an off-road vehicle is driving on cross-axle terrain or artillery shell pits, where only one wheel has traction while the other is lifted, the vehicle still has sufficient power to move forward.

What type of engine oil should be used at -30 degrees Celsius?

At -30 degrees Celsius, engine oils with grades such as 0W, 5W, 10W, 15W, 20W, and 25W can be used. The smaller the number before the W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. Therefore, at -30 degrees Celsius, 5W30 or 5W40 is recommended. Engine oil, also known as motor oil, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption and cushioning. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of the lubricant, determining its basic properties, while additives compensate for and improve any deficiencies in the base oil's performance, imparting new characteristics and making them an essential part of the lubricant.

How to Use BMW Remote Start?

BMW remote start usage method: With the traditional remote key, press the lock button three times consecutively to start the engine remotely. Below is relevant information: 1. Car remote start refers to remotely starting the engine or motor via the remote key, meaning there's no need for a person to enter the vehicle to start it. It's a function that allows starting the vehicle through remote control. The principle involves sending a signal via the key or a mobile phone to remotely start the engine, and most car models can be controlled using the car key. 2. The car remote start control system can only be installed in automatic transmission models. The reason is that automatic transmissions come equipped with a TCU control unit, which informs the ECU engine control unit about the gear position. The engine will only start when the vehicle's computer confirms that the gear is in the P (Park) position. This is to prevent the vehicle from moving unexpectedly. Aftermarket installations do not have this protective feature.

What Happens If Traffic Violation Points and Fines Are Not Handled Within a Month?

The consequences of not handling traffic violation points and fines within a month are as follows: 1. On-site enforcement: Usually, the fine should be paid promptly, with a deadline typically set at 15 days. Therefore, the vehicle owner must pay the fine in full within 15 days through methods such as banks, online payment, or postal agency points. If the fine is not paid within 15 days, a late fee of 3% of the fine amount will be charged daily. 2. Electronic enforcement (e.g., traffic cameras): The violation needs to be confirmed and the fine paid. The violation can be confirmed online or at the vehicle management office. Once confirmed, the fine must be paid in full within 15 days. However, if the violation is not confirmed, there is no issue even if more than 30 days pass, as long as it is handled before the annual vehicle inspection. Therefore, electronic violations do not need to be processed within 30 days.

Why does Volkswagen require 95-octane gasoline?

Volkswagen requires 95-octane gasoline for the following reasons: 1. Volkswagen vehicles use 95-octane gasoline because most of its models are equipped with turbocharged engines. During high-speed driving, the turbocharger operates more powerfully, which imposes strict requirements on gasoline. 95-octane gasoline has better anti-knock properties compared to 92-octane gasoline. If German cars use 92-octane gasoline for an extended period, it can lead to engine knocking, which is very dangerous. 2. The difference in gasoline grades lies in the octane rating of the additives (octane rating affects anti-knock performance). The higher the gasoline grade, the higher the octane rating, and the better the anti-knock performance, making it more suitable for high-compression engines. However, this is not absolute, as it also depends on the manufacturer's technology, tuning, and the engine's inherent characteristics.
