BYD DM-i refers to BYD's Super Hybrid Technology. The DM-i Super Hybrid system is based on a high-capacity battery and a high-power electric motor. During driving, the vehicle relies on the high-power electric motor for propulsion, while the gasoline engine primarily functions to charge the battery. It directly drives the wheels only when additional power is needed, and even then, it works in tandem with the electric motor to reduce load. Additional Information: 1. Simply put, when a DM-i model has sufficient battery charge, it operates like a pure electric vehicle, with the electric motor providing ample power for various road conditions. When the battery charge is low, the DM-i model autonomously determines whether to use electricity, fuel, or a combination of both based on system conditions. 2. According to data released by BYD, in urban driving conditions, the vehicle uses the electric motor for propulsion 99% of the time, offering a driving experience nearly identical to that of a pure electric vehicle. Additionally, the engine remains off 81% of the time under these conditions. During high-speed driving, both the engine and the electric motor provide power to the wheels, with the engine consistently operating within its most efficient range.

DM-i is an intelligent hybrid technology introduced by BYD, which stands for Dual Mode Intelligent system. It combines the advantages of pure electric drive and fuel engines. I understand that it enables vehicles to achieve ultra-long range in pure electric mode, with some models capable of running over 100 kilometers without using fuel, making daily commutes as quiet and hassle-free as driving an electric vehicle. In hybrid mode, the system automatically switches, with the engine efficiently generating electricity to support the battery, resulting in exceptionally low fuel consumption of only 3-4 liters per 100 kilometers, making it suitable for both city and long-distance driving. I believe the core of this technology lies in its economic practicality, using the internal combustion engine to generate electricity or drive to reduce mechanical wear, while the blade battery enhances safety and stability. Additionally, the intelligent system optimizes energy distribution, reducing my anxiety about fuel costs during traffic jams. Key points include a greater emphasis on electrification compared to traditional hybrids, the ability to charge externally for convenience and cost savings, and overall adding convenience to family travel. In the long run, it promotes green driving innovation and is worth recommending to those pursuing an efficient lifestyle.

Does a motor vehicle receive penalty points for violating a prohibition sign?

Yes, penalty points are given. If you see a prohibition sign while driving and still enter the area inside the outer ring road, it is called violating the instructions of the prohibition sign, resulting in a deduction of 3 points. Introduction to prohibition signs: Prohibition signs are signs that prohibit or restrict the traffic behavior of vehicles and pedestrians. Their shape is usually circular, with some being octagonal or equilateral triangles with the vertex pointing downward. Their color is usually white background, red circle, red diagonal bar, and black pattern. Function of prohibition signs: The sign prohibiting motor vehicle entry is one of the no-entry signs, indicating that all types of motor vehicles are prohibited from entering. This sign is placed at the entrance of the road section where motor vehicle traffic is prohibited.

What are the symptoms of a faulty clutch pump?

It may cause the clutch pedal to not disengage properly or become excessively heavy when pressed, especially during gear shifting. You may experience difficulty in shifting gears, incomplete disengagement, and occasional oil leakage from the slave cylinder. Once the clutch slave cylinder fails, it will most likely require replacement of the entire assembly. Introduction to the clutch pump: The clutch master cylinder and slave cylinder function as two hydraulic cylinders. Working principle of the clutch pump: The master cylinder has two oil pipes, while the slave cylinder has only one. When the clutch pedal is depressed, pressure from the master cylinder is transmitted to the slave cylinder, which then activates. The release fork separates the clutch pressure plate and disc from the flywheel, allowing gear shifting to occur. When the clutch pedal is released, the slave cylinder stops working, allowing the clutch pressure plate and disc to re-engage with the flywheel, thus continuing power transmission. The oil in the slave cylinder then flows back into the reservoir.

Will Lead-Acid Batteries Reduce Mileage in Winter?

Lead-acid batteries will reduce mileage in winter. Lower temperatures in winter can affect the driving range, but the exact amount of mileage reduction depends on factors such as temperature and usage habits. Below are the relationship between range and temperature and the reasons for the range reduction: Relationship between range and temperature: Generally, for every degree drop in temperature, the battery's capacity decreases by about 1%, leading to a corresponding reduction in range. The specific mileage reduction can be calculated based on the data displayed by the vehicle's onboard computer. Reasons for reduced range in low temperatures: The lower the temperature, the harder it is for the electrolyte in the battery to diffuse, and the slower the chemical reaction rate of the active materials at both electrodes becomes, resulting in a drop in battery voltage.

What is the correct procedure for jump-starting a car?

The correct procedure for jump-starting a car is: Park both vehicles facing each other and prepare two jumper cables. Open the hoods and connect the positive and negative terminals of both car batteries using the jumper cables—red to positive and black to negative. Start the rescue vehicle and let its engine idle. Attempt to start the stalled vehicle. If the battery is dead, the car should start quickly, and the alternator will begin charging the battery. Precautions for jump-starting: Before connecting the cables, ensure the engine is turned off. Follow the connection steps strictly: connect the positive terminal first, then the negative, and ensure the positive and negative terminals of both cars do not touch. The disconnection sequence is the reverse of the connection sequence—remove the negative cable first, then the positive. When purchasing jumper cables, choose genuine, quality-assured products. Opt for cables with an outer diameter of at least 10mm and a length of around 3 meters.
