BMW's 'i' represents gasoline engines and also stands for the fuel electronic injection system. Fuel Electronic Injection System: BMW's fuel electronic injection system is essentially controlled by a computer to manage the starting procedure of the car's engine, which enhances the engine's performance. It also significantly improves the driving experience by making the engine's output more powerful. Meaning of Rear Badging: BMW offers a variety of models, and to differentiate them, different numbers are marked at the rear of the car. Taking the newly launched 325Li as an example, '3' stands for the 3 Series, '25' represents the 2.0T engine, 'L' denotes the long-wheelbase version, and 'i' signifies fuel. These are all the meanings behind BMW's rear badging.

Can a Car Purchased in Another Province Be Licensed Locally?

It is possible to purchase a car in another province and then license it locally. Before licensing, ensure all necessary documents are complete, such as the car purchase invoice, insurance, etc. When driving the car back, you will need to obtain a temporary license plate with the assistance of the 4S store salesperson to legally drive on the road. Be sure to drive the car back to your local area within the validity period of the temporary license plate; otherwise, you will need to reapply. The local licensing process includes the following steps: 1. Pay the purchase tax: Pay the vehicle purchase tax at the local state tax bureau based on the actual parameters of the vehicle. 2. Prepare the required documents: Prepare the original and photocopy of your ID card, the vehicle's factory certificate, the copy of compulsory traffic insurance, the copy of the tax payment certificate, the vehicle identification number (VIN) rubbing, vehicle photos, and the fourth registration copy of the car purchase invoice. 3. License the vehicle: Complete the licensing process at the local vehicle management office.

What are the functions of ETC?

ETC functions: Through the dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles passing through highway or bridge toll stations without stopping while paying the highway or bridge tolls. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and environmentally friendly: Green and low-carbon, vehicles passing through toll stations without stopping can reduce noise and exhaust emissions, thereby reducing pollution; Cost-saving: Saves expenses, reduces the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on tolls; Improved efficiency: The theoretical efficiency of vehicles passing through ETC lanes can be increased by 2-3 times or more, making traditional ETC more updated, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What is the actual fuel consumption of the 240-horsepower J6?

FAW J6-240 is a truck equipped with a diesel engine, with a fuel consumption of 20 liters per 100 kilometers. The fuel consumption of a vehicle is not only related to the vehicle itself but also to the driver's habits and road conditions. The factors affecting fuel consumption are as follows: Different models have different fuel consumption: With the same amount of fuel, different models inherently have different fuel consumption due to their design. The weight of the vehicle plays a significant role; small cars and large trucks will naturally have different fuel consumption levels. Different vehicle conditions lead to different fuel consumption: Even the same vehicle with the same amount of fuel will consume more when driving at high speeds compared to steady road conditions. Additionally, a loaded truck consumes more fuel than when it is unloaded. Different driving habits result in different fuel consumption: With the same model and fuel amount, the driver's personal habits can also affect fuel consumption. For example, driving with windows open on highways increases air resistance and fuel consumption. Sudden stops, hard braking, and rapid acceleration also lead to higher fuel consumption, while warming up the engine before ignition can help save fuel.

Why Is the Air Conditioning Noise So Loud When Driving?

Here are the reasons why the air conditioning noise is particularly loud when driving: 1. Air conditioning pump: Abnormal wear of the air conditioning pump leads to unusual noise. 2. Air conditioning belt: The air conditioning belt is loose, or the tensioner pulley has insufficient tension. 3. Blower: Leaves or debris have entered the air conditioning blower. 4. Malfunction: The blower is faulty. Below is additional information on how to resolve loud air conditioning noises in cars: 1. Replace the air conditioning pump: If the air conditioning pump is abnormally worn and produces a 'clattering' noise, it should be replaced at a 4S shop. 2. Replace the air conditioning belt: If the air conditioning belt is loose or the tensioner pulley has insufficient tension, causing a 'squeaking' noise when the air conditioning is on, the solution is to replace the belt and tensioner pulley. 3. Repair the blower: If leaves or other debris have entered the air conditioning blower, you can diagnose this by adjusting the air conditioning airflow to see if the noise changes. If it does, the blower likely has leaves or other foreign objects inside. The repair method involves removing the air filter and cleaning the blower.

Can BYD Electric Vehicles Charge Without Turning Off the Engine?

Charging a BYD electric vehicle without turning off the engine can easily lead to safety accidents, so it is recommended to turn off the engine before charging. Here are some precautions for charging new energy electric vehicles: 1. The choice of flame-retardant wires is crucial: When charging, select qualified flame-retardant wires with leakage protection devices. Only high flame-retardant charging cables can prevent electric vehicle fires during charging. 2. Pay attention to the placement of the charger: The charger should be placed on the footrest, and it is strictly forbidden to cover it with items or place it on the seat cushion or inside the seat bucket. Randomly extending the power cord and frequently pulling it can easily cause loose connections, aging wires, and short circuits due to damaged wire insulation. 3. Remember to turn off the ignition lock: Additionally, the ignition lock must be turned off. If the ignition lock is left on while charging, the battery voltage will rise, which can burn out the ignition lock and cause a short circuit fire. If the charger is dropped or collided, the fan can easily be damaged. During charging, observe whether the charger's cooling fan is operating normally. If the fan is damaged, it should be repaired or replaced with a new charger promptly.
